Red Sea Coral Colors C is a complex of 8 “light” metals that includes Iron, Manganese, Cobalt, Copper, Aluminum, Zinc, Chrome and Nickel. These micro-elements are essential to many bio-chemical metabolic processes, including respiration, production of energy, chlorophyll and photosynthetic catalysts. C elements are related to the green/yellowchroma-proteins.Weekly dosing - Soft CoralsTest the Color Elements every week and dose each supplement to replenish back to the optimal levels.Daily dosing - SPS coralsEnsure that all of the Color Elements are at optimal values and run the aquarium for4 days at a stable salinity (compensate for evaporation daily) without adding anysupplements. At the end of the 4 days test the Color Elements and calculate the “4 day dosage” of each supplement to replenish back to the optimal levels. Add the “4 day dosage” to the system. Divide this “4 day dosage” by 4 and use as the daily dosage for the next week.After a week of adding the daily dosage, test the Color Elements and calculate the adjusting dosage of each supplement to replenish back to the optimal levels.
If the adjusting dosage is significantly different from the previous daily dosage amend (increase/decrease) the daily dosage as appropriate.
If the measured level of a specific element is above the optimal level wait for the excess of the element to be depleted before restarting the daily supplementation with the amended daily dosage.
Continue testing all of the elements every week and make adjustments to the dailydosages as required. As your corals grow or you add or remove livestock the uptake of the elements in your aquarium will gradually change. It is recommended to keep a log book of the weekly measurements and dosages.If you miss one or more days of supplementing add the complete amount that you have missed but do not exceed the maximum recommended daily increase for any of the elements.

TRACE COLORS A
Iodine, Bromine and Fluorine supplement that promotes the Pink colors in corals
IODINE+ Supplement is part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.
IODINE+ Supplement contains iodine and other halogens that are associated with many biological processes, one of them being the production of the pink pigments in the soft tissue of corals.
The halogens act both as antioxidants and oxidative agents within the soft tissue and mucus layer of corals, reducing the possibility of coral bleaching.
In active reef systems, these elements are depleted quickly due to their high oxidative abilities and reactivity with organic materials. Iodine and bromine are related to the pink chromo-protein (pocciloporin).
For best results in displaying coral colors use Red Sea’s NO3: PO4– X.
1ml will raise the iodine level of 100 liters (25 gal) by 0.03ppm

Water Level Sensor
Ultra Reliable. The ReefATO+ sensor features a built-in backup sensor 1" above the primary sensors to automatically shut down the ATO pump in the event of an overfill. With multiple probes built onto the sensor, an indication of actual water level can always be seen on the ReefBeat App.
Temperature Monitoring
The temperature sensor integrated in the ATO+ sensor has been pre-calibrated to give an accuracy of ±0.1°. The ReefBeat App allows you to set a narrow “desired” temperature range, and a slightly wider “acceptable” range, that will be seen on-line in the ReefBeat App and in the full temperature logs. If the temperature goes outside the acceptable range, you will get a notification to your smartphone. The detailed logs will show you the minimum, maximum and average temperatures at 15-minute intervals for the past 28 days.
ATO Pump
Quiet, variable flow, 12 vdc ATO pump
Diameter of just 1.8” to fit inside small ATO reservoir openings
Max flow rate 75 gph, Max head 8’, power 6–10W

Safe Introduction of New Corals
DipX is a highly effective dip for safely introducing new corals and live rocks to your aquarium.
A simple 15-minute bath in DipX before placing a new coral in the aquarium will drive away unwanted “hitchhikers”, thereby maintaining the safety of your reef.
New corals often come with unwanted “hitchhikers” hidden deep inside the corals’ crevices. These various tiny creatures are usually invisible to the naked eye, and once in the aquarium, they can migrate to other corals and damage your delicate reef eco-system.
Over the years, reef hobbyists have used generic baths solutions such as fresh water, Iodine, and even household disinfectants, all of which repel some of the hitchhikers, but not all of them.
For the past few years, we have been cultivating tanks with infested corals and comparing a wide range of commercially available dips and other repelling ingredients, examining both their effectiveness and their overall safety for the corals.
The result is DipX – a unique blend of essential oils, without inorganic disinfectants. Our tests have shown that DipX is completely safe for all kinds of corals and more effective than any other solution we tested.
Corals that were bathed in DipX still repelled unwanted “hitchhikers”, even though they were previously dipped in other solutions On the other hand, corals that were dipped in other solutions after they were bathed in DipX did not repel anything.

Refractometer for measuring salinity of seawater for reef aquariums
*
Calibrated to measure absolute salinity of seawater, not brine (NaCl)
*
High resolution display focuses on the range relevant for reef aquariums
Maintain proper salinity level with greater precision and convenience. Red Sea Seawater Refractometer is designed specifically to measure the absolute salinity of seawater, not brine (NaCl) for true readings essential for reef aquariums housing sensitive corals. High-resolution dual scale display (salinity in ppt and specific gravity) focuses on the range relevant for reef aquariums, eliminating confusing extraneous graduations. Dual scale range of 20-40 PPT/77°F and 1.010-1.030 S.G.
Red Sea Seawater Refractometer has been calibrated for the specific ionic content of seawater according to the most advanced international laboratory standards for practical salinity measurements. High accuracy seawater refractometer features Automatic Temperature Compensation for exceptional accuracy measuring the absolute salinity of seawater at a temperature of 25°C/77°F.
Main Features
Directly reads the absolute salinity of seawater at 25°C/77°F (no need for seawater or temperature compensation factors).
Specifically designed for the ionic content of seawater (NSW) for more accurate salinity measurement (industry standard refractometers are calibrated for salt brine).
Calibrated for seawater (NSW) at 25°C/77°F, the normal temperature range for reef aquariums (most standard refractometers are calibrated at 15°C/59°F).
Easier to read, higher resolution display, focused to the relevant range for reef aquariums of up to 40ppt.
Includes Integrated Automatic Temperature Compensation (ATC) for accurate measurement at standard ambient temperature.
Did You Know?Measuring the salinity of seawater with a refractometer calibrated for brine (NaCl) solution will result in a deviation of up to 1.5 ppt!
Directions for use
Clean the glass prism and translucent flap of the refractometer with deionized (DI) water at 22-25°C and dry thoroughly with a soft cloth.
Hold the refractometer horizontally and open the flap.
Using the pipette provided, place a small sample of the seawater to be tested on the glass prism. Do not immerse the refractometer into the seawater.
Close the flap on the sample and wait for 15 seconds to allow for the temperature of the sample and the refractometer to equalize.
Point the prism end of the refractometer to a light source and look through the eyepiece. (Note: The refractive index is also dependent on the wavelength of the light source and therefore a light source close to daylight should be used.)
The top of the screen will be blue and the bottom will be clear/white. The dividing line between the blue and white sections is where the reading should be taken.
Adjust the focus for your individual eyesight by rotating the eyepiece until a sharp picture is achieved.
Read the seawater salinity in ppt and/or the equivalent specific gravity (S.G.) at 25°C.
Clean the glass prism and translucent flap of the refractometer with DI water and dry thoroughly with a soft cloth.
CalibrationAlignment should always be carried out with the instrument at 22-25°C. Allow the refractometer to stand at this temperature for 30 minutes before alignment.
Remove the cover from the alignment screw.
Place a sample of DI water on the glass prism and check the salinity reading as directed above.
If the reading is not exactly on the zero ppt mark on the scale, adjust the position of the reading by rotating the alignment screw with the screwdriver provided until the reading is zero ppt.
Replace the cover from the alignment screw.
StorageTo prevent the formation of condensation inside the refractometer, store in a dry environment.
General InformationRefractometers are optical instruments that measure the refractive index of a solution, which will vary according to its ionic composition, concentration and temperature. For accurate results, refractometers must be calibrated for the specific solution to be tested and in the correct temperature range.
Red Sea's Seawater Refractometer has been calibrated for the specific ionic content of seawater according to the most advanced international laboratory standards for practical salinity measurements. Measuring the salinity of seawater with a refractometer calibrated for brine (NaCl) solution will result in a deviation of up to 1.5 ppt.
Red Sea's Seawater Refractometer includes automatic temperature compensation. However, to avoid compensation errors, it has been calibrated at 25°C, the normal temperature range for reef aquariums. Both the ambient temperature and the water sample temperature will influence the refractive index and therefore it is recommended to use the refractometer in environments where the ambient temperature and the water to be tested are between 15-35°C.
Over time, the optical elements inside refractometers can become misaligned. Therefore, before first use and thereafter on a regular basis, the alignment of a refractometer should be checked and adjusted as necessary.
Red Sea's Refractometer DisplayThe PPT scale on Red Sea's Seawater refractometer is calculated using an algorithm for seawater and therefore will give a reading of the Absolute Salinity of seawater.
The PPT scale on regular salinity refractometers are calculated using an algorithm for Brine. Using a Brine refractometer for Seawater will give an error of approximately 1.5ppt in the salinity reading.
About SalinitySalinity is a general term describing the concentration of salt in water. However, solutions of different type of salts have different refractive indexes. Brine is a solution of Sodium Chloride (table salt) that contains 2 chemical elements. Seawater contains approximately 70 chemical elements that include Calcium, Magnesium, Potassium etc. in addition to the Sodium Chloride. Seawater and Brine of the same salinity (i.e. the same weight of salt/liter) have different refractive indexes and will give different salinity readings if measured on the same refractometer.
Refraction & Refractive IndexAll transparent materials such as liquids refract (distort) light. All transparent materials refract light differently and have what is called a "refractive index" which means how much a particular material distorts light. Different concentrations of the same liquid have different refractive indexes. The scale of a refractometer is calculated by using a mathematical algorithm that relates the measured refraction to its concentration for a specific liquid.
Refractive Index and TemperatureThe refractive index of liquids change with temperature and therefore has a major effect on measuring salinity with a refractometer. The algorithm for defining the PPT (and S.G.) scale for a refractometer is calculated for a specific temperature.
PPT readings from refractometers that are not calibrated for reef aquariums (i.e. 25°C) need to be adjusted according to a conversion table to give the actual PPT at the aquarium temperature. This is often a cause for misinterpretation of refractometer readings.
For example, using a seawater refractometer calibrated at 20°C will give a PPT reading that is approximately 1-1.5ppt lower than the absolute salinity of the same water sample at the normal aquarium temperature of 25°C.
Therefore, Red Sea's Seawater Refractometer calibrated at 25°C/77°F directly reads the absolute salinity of seawater with no need for temperature compensation factor)
ATC - Automatic Temperature CompensationTemperature is probably the biggest cause of wrong readings with a refractometer. Calibration and testing of water samples should be done after the refractometer and water sample have equalized at the correct temperature.
Automatic Temperature Compensation (ATC) compensates for a few degrees of difference between the ambient temperature and the calibrated temperature of the refractometer. Larger temperature variations will give an error of approximately 1.0ppt in the salinity reading.
NOTE: ATC does not adjust the PPT reading of a refractometer to the temperature of the aquarium.

TRACE COLORS B
Potassium and Boron supplement that promotes the Red colors in corals
POTASSIUM+ Supplement is part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.
POTASSIUM+ Supplement contains potassium and boron that are associated with many biological processes, one of them being the production of the red pigments in the soft tissue of corals.
Potassium plays an essential role in the transportation of coral nutrients within the soft tissue (including the nutrients provided by the zooxanthellae). Potassium and boron significantly affect the alkalinity of a coral’s soft tissue and the formation of aragonite in its skeleton. Potassium is related to the red chromo-proteins.
For best results in displaying coral colors use Red Sea’s NO3: PO4– X.
Liquid supplement:
1ml will raise the potassium level of 100 liters (25 gal) by1.75ppm.
