Flatworm eXit itself is quite safe to fish and invertebrates.However, the body fluids of flatworms can be toxic to some reef inhabitants when present in a too high concentration. This body fluid is sometimes excreted when flatworms die.So when you use this product it is important to do the following first:1] Siphon out as many flatworms as possible.2] Keep sufficient fresh activated carbon in a canister ready.3] Turn off UV, ozone and remove activated carbon. Keep the skimmer turned on.Important remarksBelow given remarks are a.o. meant to reduce the amount of the flatworm’s toxic body fluids in the water.Many people have treated their reef tank(s) successfully using Flatworm eXit without any problems. The most important factors are reducing the number of flatworms before commencing with the treatment and reducing the amount of the flatworm’s body fluids, released when they die, as fast as possible.Do not underestimate the number of flatworms in your system. In a few cases a significant number of flatworms can be hiding in for example crevices. Blow in such and any other potential hiding places water to blow any flatworm out of there. For that purpose you can use a powerhead or a turkey baster. Siphon out those flatworms as well.Furthermore do not underestimate the amount of toxic body fluids these flatworms can excrete. This can be reduced significantly by really siphoning out the flatworms before commencing with the treatment. Further significant reduction is accomplished by siphoning out as many dead flatworms as you can.Any body fluids released by the dead flatworms in the water has to be reduced further by using about 1 pound of fresh high quality carbon for every 50 gallons. The carbon has to be used in a canister with a sufficient forced water flow.Take sufficient time for treating the tank. That is, do not treat your tank in a hurry. Also take time to monitor your tank for at least 6 hours after the treatment.It is also wise to have at least 25% water ready for a water change if required.Dosage:Read all the above text before commencing with the treatment!- 1 drop for every 4 liters or 1 gallon.The dropper contains approx. 300 drops (10 ml). The dropper cap holds approx. 90 drops.So 1 cap full is good for 360 liters or 90 gallons.Add it in a high flow area of the tank. If you want to treat a refugium only and if it’s volume is too small for using a powerhead then mixing should be done manually.- It should start to work within 30 minutes.- If within 45 minutes no visible death of flatworms occurs add 50% more.- As soon as the flatworms start to die commence with the activated carbon to take out any toxic body fluids. Also see the above given important remarks.- After an hour or so you can turn any UV or ozone on again.Keep out of the reach of children! Only for aquarium hobby use.

AquaVitro – Remediation uses bio-augmentation, a natural and non-chemical method, to improve water quality. It provides bacteria that break down excess food, waste and detritus in freshwater and marine systems. It will also reduce excess nutrients (e.g. ammonia, nitrates, nitrites and phosphates) that may fuel the growth of nuisance and disease-causing organisms.
The bacteria species in remediation™ thrive in fresh or salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike traditional nitrifying bacteria, this bacterial blend can adapt to harsh or low oxygen environments and continue to multiply and improve water conditions. Biopolymers produced by established bacterial colonies trap particulates and increase water clarity. The species of bacteria in remediation™ have been developed for use in aquaculture, where sludge and excess organics must be controlled to avoid disease and livestock losses. This bacterial blend is hardy enough to survive harsh aquaculture conditions, and it will thrive in your aquarium.
Directions:
Shake well before use. Turn off UV/ozone. Use 5 mL for each 40 L (10 US gallons). Then use a maintenance dose of 5 mL for each 80 L (20 US gallons) with additions of livestock or the disruption of the biofilter through cleaning or medications.
Antibiotics should be removed with fresh carbon and a water change before adding bacteria. Allow 2 or 3 days for the bacteria to become established before using UV sterilizers or ozone. Recurring problems with high nutrients can indicate overstocking, overfeeding or inadequate filtration.

Restores magnesium by employing the most concentrated (90,000 mg/L), fully dissolved magnesiumFirst and only liquid magnesium supplement that does not contain ammonia
Overview
Like calcium and strontium, magnesium is used in the calcification of skeletons of reef organisms. In many cases, magnesium is used in place of calcium for calcification. In addition to its role in calcification, magnesium is used by organisms ranging from bacteria, to coralline algae to fish.How can you be sure if magnesium levels are deficient? There are a couple of indications; severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels (more on ionic imbalance).The best way to tell if you need a magnesium supplement, though, is to test for it using a magnesium test kit such as Seachem's Reef Status®: Magnesium & Carbonate and Borate Alkalinity.If you've determined your magnesium levels are low, supplementation with ions™ is necessary. ions™ restores magnesium by employing the most concentrated (90,000 mg/L), fully dissolved magnesium and does so without adding any ammonia. Other liquid magnesium supplements inherently contain ammonia because the magnesium chloride used in their production contains ammonia. This is a result of the mechanisms for deriving and/or producing magnesium chloride. aquavitro has gone to considerable lengths to remove this contaminant and a proprietary process makes ions™ the first and only liquid magnesium supplement that does not contain ammonia.Using a fully dissolved magnesium is critical. Some magnesium supplements use a magnesium source that is simply not soluble, that is, unavailable. This means it can never be utilized by reef organisms, and is, consequently, of no value. If the product itself is milky white or the instructions direct the user to shake well, more than likely, a substantial amount of magnesium is not being utilized (the same is true of calcium products). ions™ also includes strontium and boron in the NSW ratio of 1.7:1 to avoid ionic imbalance with long term use.Directions
Beginner: Use 5 mL for every 90 L (25 US gallons) twice a week. Check magnesium once a week and adjust amount or frequency accordingly. Note: each inner cap thread is approximately 1 mL.Advanced: Check magnesium level, then follow addition regimen above until magnesium is adjusted to 1200-1350 mg/L. Each 5 mL/90 L (25 US gallons) will raise magnesium by about 5 mg/L. Quantity or frequency can be adjusted, but do not exceed 25 mL/90 L (25 US gallons) per day. Thereafter, use as required to maintain magnesium.Unlike competing products that require multi-day interval dosing. ions™ can be dosed daily and within minutes of the entire aquavitro line.

Many competing buffers for reef aquaria are simply sodium bicarbonate. Such buffers have a pK of only 8.0 in saltwater and simply are unable to maintain a pH above 8.0. The low buffering pK is a function of the low carbonate/bicarbonate ratio.
eight.four™ supplies a properly balanced (carbonate/bicarbonate) buffer system that yields an industry leading pK of 8.6 which makes pH maintenance of 8.3-8.5 easy. A higher pK increases the buffer's ability to counteract inevitable acidic sources in the water. eight.four™ will safely raise marine pH while adjusting alkalinity. eight.four™ contains a concentrated, balanced blend of bicarbonate and carbonate salts designed to restore disrupted buffer systems and increase carbonate alkalinity.
If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained, the system may be ionically unbalanced. Check magnesium levels. If magnesium is low, use Ions. However, if magnesium levels are within optimal range, the buffer ratio has likely been disrupted (the buffer ratio changes as a natural consequence of the buffer's ability to counteract acidifying sources such as organic acids). You can raise pH without raising alkalinity using balance™.
Unlike competing products that require multi-day interval dosing when combined with carbonate supplements, eight.four™ can be dosed daily and within minutes of our calcification as well as balance and ions

Calcification is a concentrated (140,000 mg/L) optimized blend of ionic and bioavailable gluconate-complexed calcium designed to restore and maintain calcium to levels found in natural seawater, without affecting pH. These two forms of calcium are combined in calcification to provide the hobbyist with a convenient way to ensure peak coral growth and health.
Ionic calcium is readily available, while the gluconate-complexed calcium confers several benefits. The uncharged calcium in calcification is readily absorbed with less physiological work than is required for the absorption of ionic calcium. Using calcification, it is not necessary to maintain the excessively high concentrations of calcium (about 450 mg/L or more) often recommended by others. In fact, excellent growth of corals and coraline algae is achieved with total calcium concentrations as low as 380 mg/L. Used up to four times recommended maintenance dose, the gluconate polymer will not accumulate or encourage the growth of undesirable algae. The polymer itself is beneficial as a food source not only to the corals and other invertebrates, but also to denitrifying bacteria, actually promoting the natural anaerobic denitrification process in live rock and other substrate. Furthermore, the use of this gluconate polymer allows calcium, strontium, and magnesium to be utilized more readily than they would otherwise and also helps to stabilize them in solution without depleting alkalinity.
Some prefer not to use complexed calcium because of concern about adding organics to the aquarium. This is not a valid concern. The amount of organics added with complexed calcium is insignificantly small when compared to the organics released by most reef creatures, even in a no feed, no nutrients approach. Since complexed calcium products employ lactate or gluconate, the naive misconception that these products contain sugars has arisen. While these components are related to sugars, they are oxidized aldehydes and do not react or behave as sugars. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.
Unlike competing products that require multi-day interval dosing when combined with carbonate supplements, calcification™ can be dosed daily and within minutes of our eight.four as well as the entire aquavitro reef line.

When used as directed Reef Buffer will raise the pH of your reef system to 8.3 without fear of accidentally overshooting the pH to a dangerous level. Whereas competing products simply use sodium bicarbonate, Reef Buffer is made with a blend of carbonate and bicarbonate salts. This blend of salts results in Reef Buffer yielding a pK of roughly 8.6 in saltwater.
The pK of a buffering agent is equivalent to the pH around which that buffer most strongly buffers. One would presume, then, that the pK of a saltwater buffer should be 8.3; however, the multitude of organic acids produced by the inhabitants of a reef system forces pH downward to a much greater degree than in a non-reef, marine system. A buffer with a pK of 8.3 would end up yielding a pH more in the range of 8.0-8.2. Reef Buffer's higher pK (8.6) allows for greater pH stability in a reef system where the bioload is significantly more than in a fish only system. Competing products are not designed specifically for the reef environment, so their pK is too low (in most cases, pK 8.3). At this pK, the proper pH can never be reached in saltwater.
Reef Buffer will also raise carbonate alkalinity; however, when pH is not an issue, Reef Builder or Reef Carbonate should be your first choice for a carbonate alkalinity supplement.

Reef Advantage Magnesium is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Reef Advantage Magnesium contains no ammonia. This is a common contaminant in every liquid magnesium supplement on the market.
Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper magnesium levels. The most frequent causes of magnesium deficiency are use of kalkwasser, frequent overdosing of a carbonate additive, or low levels in the salt mix itself. Kalkwasser, for instance, precipitates magnesium as magnesium hydroxide while excess carbonates precipitate it as magnesium carbonate. In both cases, this means that magnesium that was present in the water is now unavailable. Of the two, magnesium hydroxide and magnesium carbonate, the former is more problematic; it is extremely insoluble. Once magnesium has precipitated as magnesium hydroxide, it will never redissolve. Magnesium carbonate will redissolve; however, it does so slowly. So, while it will go back into solution, there will be a significant portion of time in which magnesium levels are depleted.
