Aquavitro Shrimp pHa is one part of a two-part system which aids in replicating the water chemistry found in the native habitats of freshwater shrimp by buffering water to the natural pH for each specific type of shrimp. Used according to directions, shrimp pHa maintains the proper pH parameters of freshwater shrimp while also softening water and supporting growth of plants in shrimp aquaria. shrimp pHa is made from a unique buffer system that is extremely stable and does not add sodium, which can damage plants in the aquarium. KEY FEATURES: Premum AquaVitro line Lowers pH Two-part system for targeting pH in freshwater shrimp aquariums DIRECTIONS: Use when setting up an aquarium and when making water changes. Use with shrimp pHb to target a pH. All doses given are for 20L (5 US gallons). Doses can be safely doubled if needed. In cases of sensitive shrimp or to avoid the risk of any pH shock, consider breaking dosing up over a 12 -24 hour period. To simply lower the pH in established aquaria: Add 2.5mL (½ tsp) of shrimp pHa per 20L (5 US gallons) every 12 hours until you achieve your target pH. Do not exceed this dose. Rapid pH changes can be very detrimental to shrimp. Some aquariums may require repeated dosing to overcome the buffering capacity of certain substrates and decorations. This is particularly the case with humate based soils. *Product not to be sold online.Best Before Guarantee: 05/01/2026

Balance is an optimized blend of sodium and potassium hydroxides with a NSW ratio (27:1) of sodium to potassium to avoid ionic imbalance with long term use. KEY FEATURES: Premium AquaVitro line Balances the carbonate buffer system ratio Raises pH without affecting calcium and alkalinity Hydroxide blend DIRECTIONS: Balance is intended to be used to raise pH when all other parameters (alkalinity, calcium, magnesium) are at optimal levels, but pH is still low. The amount of balance needed to raise pH to the desired level will vary widely, depending upon the buffering capacity and quality of your tank water. For reference purposes only, 5mL will raise 55L (15 US gallons) of salt water by about 0.1 pH units. Add Balance in small increments, and check pH after at least 3 minutes before adding additional increments. *Product not to be sold online.Best Before Guarantee: 05/01/2027

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. KEY FEATURES: Premium AquaVitro line A concentrated (140,000 mg/L) optimized blend of ionic and bioavailable gluconate-complexed calcium Prevents calcium precipitation/alkalinity depletion Maintains peak coral growth DIRECTIONS: Beginner Use 5mL for every 70L (18 US gallons) twice a week. Check calcium once a week and adjust amount or frequency accordingly. Advanced Check calcium level, then follow addition regimen above until calcium is adjusted to 380-400 mg/L. Each 5 mL/70 L (18 US gallons) will raise calcium by about 10 mg/L. Quantity or frequency can be adjusted, but do not exceed 15 mL/70 L (18 US gallons) per day. Thereafter, use as required to maintain calcium. *Product not to be sold online.Best Before Guarantee: 05/01/2027

Pond AQUA ESSENTIAL water conditioner is a highly concentrated all-in-one water conditioner that instantly makes tap water safe for fish by removing chlorine, chloramine and detoxifies heavy metals commonly found in tap water. Pond AQUA ESSENTIAL water conditioner instantly removes toxic ammonia, nitrate, and nitrite levels in your pond. Toxic ammonia is continually released by fish through their gills, urine, and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish. This unique formula binds with ammonia, nitrite, and nitrate rendering them non-toxic and allowing the biofilter to remove them more efficiently. Use at pond start-up and whenever adding or changing water or when tested levels of ammonia, nitrates or nitrite are high.  Shake the bottle well directly before use. Add 50 ml per 500 gallons of pond water to treat tap water. Add 50 ml per 100 gallons of pond water to remove ammonia, nitrite, and nitrate. If after 7 days test results still show ammonia or nitrite, perform a partial water change. Best Before Guarantee: 30/01/2027

API AQUARIUM SALT is made from evaporated sea salt and is a must-have for your aquarium! AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished. Use API AQUARIUM SALT in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive. Add 1 rounded tablespoon for every 5 gallons or 0.5 teaspoon for every gallon of aquarium water.

Reef Builder raises carbonate alkalinity (KH) without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3. Used as directed, Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Reef Builder and Reef Buffer may be used together. Use Reef Builder to raise carbonate alkalinity without affecting pH. Use Reef Buffer to raise carbonate alkalinity and pH. Reef alkalinity should be maintained at 3–5 meq/L (8–14 dKH). Alkalinity should not be allowed to fall below 2 meq/L.Best Before Guarantee: 30/12/2025
