RRP: £15.69Our price: £12.55You save: £3.14 (20%)View A frequent occurence in reef systems is low pH, while calcium and alkalinity are at optimal levels. Raise one and the others may fall. One of the primary reasons for this is an improper carbonate/bicarbonate ratio. The buffer ratio changes as a natural consequence of the buffer’s ability to counteract acidifying sources such as organic acids (produced naturally from waste) or introduced from non-pH controlled husbandry products. In this case, adding more buffer would unnecessarily result in a rise in alkalinity and a drop in calcium. The first product of its kind, balance™ ends this see-saw effect. It resets this ratio by converting bicarbonate into carbonate in order to reassert a higher pH without affecting calcium level.

Acid buffer 300gRRP: £14.99Our price: £11.25You save: £3.74 (25%)ViewAcid Buffer is a non-phosphate buffer to lower pH and buffer with Alkaline buffer. Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Acid buffer lowers pH and buffers between 6.0 and 8.0 when used with Alkaline buffer. As Acid Buffer lowers ph it coverts carbonated alkalinity (KH) into available CO2.

Aquavitro Reef 8.4RRP: £16.49Our price: From £13.20You save: £3.29 (20%)View 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.
Aquavitro Reef BalanceRRP: £16.49Our price: From £13.20You save: £3.29 (20%)View A frequent occurence in reef systems is low pH, while calcium and alkalinity are at optimal levels.

Aquavitro Reef FuelRRP: £16.49Our price: From £13.20You save: £3.29 (20%)View fuel™ is a comprehensive carbohydrate, vitamin, amino acid, polyunsaturated fatty acid, and trace element supplement developed to address nutritional requirements commonly associated with corals. fuel™ contains ascorbic acid in a base of chlorella, which contains a rich assortment of amino acids and vitamins. The health benefits of chlorella are widely known and while spirulina, a similar algae, has been regularly used in the industry, aquavitro™ is the first to utilize the vastly superior chlorella. fuel™ is formulated to provide nutrients available from natural tropical reef waters.
Aquavitro Reef IonsRRP: £16.49Our price: From £13.20You save: £3.29 (20%)ViewLike 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™: Magensium & 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.Beginner: Use one inner capful (7 ml) for every 125 L (35 gallons*) twice a week. Check magnesium once a week and adjust amount or frequency accordingly.Advanced: Check magnesium level, then follow addition regimen above until magnesium is adjusted to 1200-1350 mg/L. Each 7 mL/125 L (35 gallons*) will raise magnesium by about 5 mg/L. Quantity or frequency can be adjusted, but do not exceed 35 mL/125 L (35 gallons*) per day. Thereafter, use as required to maintain magnesium.
Cichlid lake saltOur price: From £11.49View Cichlid Lake Salt™ is a chemically sound blend of salts designed to replicate the natural environment of Cichlids. It contains all physiologically essential elements such as magnesium, calcium, sodium, potassium, and includes trace components such as iron, aluminum, and iodide.

Use Seachem’s Cichlid Trace™ to restore and maintain important trace elements between water changes.

Reef Advantage CalciumOur price: From £13.49ViewReef Advantage Calcium™ is a non-caustic (pH 8.3–8.6) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Reef Advantage Calcium™ also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. Unlike limewater (kalkwasser), Reef Advantage Calcium™ does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity.
Reef Advantage MagnesiumOur price: From £9.99ViewReef 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 StrontiumOur price: From £9.99ViewReef Advantage Strontium™ restores and maintains strontium to levels found in natural sea water. Strontium is utilized by corals in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth. It is most useful in densely populated aquariums requiring a continuous supply of strontium. Reef Advantage Strontium™ is a highly concentrated (30,000 ppm), ionically balanced strontium supplement. 
Reef BufferOur price: From £13.49ViewReef Buffer™ will also raise carbonate alkalinity; however, it is intended primarily for use as a buffer in a reef system where the maintenance of a pH of 8.3 is often difficult. When pH is not an issue, Reef Builder™ or Reef Carbonate™ should be your first choice for a carbonate alkalinity supplement.
Reef BuilderOur price: From £13.99ViewReef Builder™ raises carbonate alkalinity without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3. Carbonates and calcium are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Reef Builder™ will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. 
Reef CalciumOur price: From £8.99View Reef Calcium™ is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. 
Reef CompleteOur price: From £8.99ViewReef Complete® is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health.
Reef Complete® also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium.
Reef DipOur price: From £9.99ViewReef Dip™ contains elemental iodine complexed to a protective slime coat for safely and gently disinfecting corals. It is effective against bacteria, fungus, and protozoans. It may be used prophylactically (without evidence of disease) or to remedy diseased specimens. It is safe to use with both stony and soft corals. It is also safe for anemones and polyps. 
Reef IodideOur price: From £8.29ViewReef Iodide™ is a concentrated (8,000 mg/L) stabilized potassium iodide source for reef aquaria that will restore and maintain iodide levels to those found in natural sea water. It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions. Iodine is as toxic as chlorine and should never be used in a reef system. However, iodide is as safe as chloride.
