TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.

By SunGrow Store

SunGrow 20 Pcs Large Catappa Indian Almond Leaves for Fish Aquarium Tank, 8-Inches, Leaf for Successful Breeding & Creating Rainforest Environment, Water Conditioner Leaves for Shrimps, Betta

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 helps 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. As they start to do so, they will soften and your fishes, shrimp, and even snails will start to use the leaves as they see fit. Shrimps have been known to nibble on leaves, while fishes sometimes hide under them.
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.
