POWERFUL TREATMENT: Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine.

REMOVER: Seachem Prime immediately and permanently removes chlorine and chloramine, successfully allowing the bio filter to remove ammonia, nitrite, and nitrate while they are detoxified for 48 hours.

DETOXIFIER: Seachem Prime effectively detoxifies ammonia, nitrite, and heavy metals found in the tap water at typical concentration levels, providing a ideal environment for your betta, tetra, or other fish.

USE: Use 1 capful (5 mL) of Seachem Prime for each 200 L (50 US gallons) of new or replacement water. For best results, add Seachem Prime to new water first. For exceptionally high chloramine concentrations, a double dose may be used safely. For smaller volumes, use 2 drops per gallon.

SAFETY: In case of an emergency, the 5x dose of Seachem Prime may be used for both ammonia and nitrite. Use a ½ dose if the water temperature is > 30°C (86°F) and chlorine or ammonia levels are low.

Features

Give a no-stress home to your betta --- When fish are given their native ambiance, they tend to grow stronger and heartier. By balancing the pH level, our leaves provide ideal water conditions. The Indian Almond leaves are considered to have beneficial properties and increase fish appetite making them happy.

Have a breeding pet? Add catappa --- The tropical fishes create bubble nests using a floating leaf or a plant to anchor their bubbles. So if your tank has any one of the breeding tropical fish like tetra, guppy, platies, molly, cichlids, just add these leaves and see them anchoring their eggs over IAL. That is a sight to behold. In ancient times, the Ketapang leaves were used in folk medicine for indigestion.

Benefits other fish and snails too --- The tea water has many advantages for fishes like tetra, discus, and goldfish. It is good for rasporas and many dwarf cichlids too. Apart from that, snail owners can benefit from the magical leaves. Giving your fish such an ambiance calms them down and aids in overall development. It helps in imparting color to them and makes their scales firmer.

Shrimps, fishes and snails love them --- Depending on your tank size and the pH level needed, drop a few leaves into your tank (If you want to be exact about the pH level, you can use a pH tester or a drop checker). Over the next few days, the leaves will slowly submerge to the bottom.

Adds beauty to nano tanks, small bowls and jars --- The Catappa leaves from SunGrow are unprocessed so you know what goes into your tank. They look pretty in a nano tank and add aesthetic beauty to your planted tank. You may even add these in individual betta jars or bowls.
