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

Aquavitro Shrimp pHb 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 pHb maintains the proper pH parameters of freshwater shrimp while also softening water and supporting growth of plants in shrimp aquaria. shrimp pHb 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: Premium AquaVitro line Raises pH Two-part system for targeting pH in freshwater shrimp aquarium. DIRECTIONS: Use when setting up an aquarium and when making water changes. Use with shrimp pHa 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 raise the pH in established aquaria: Add 2.5mL (½ tsp) of shrimp pHb 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. *Not to be sold online.Best Before Guarantee: 31/07/2025
