Product Description: Olive leaf is widely used in Southeast Asia and other regions, and is always used in the breeding environment of arowanas and flower arowanas. The water color will be light coffee or coffee brown, and the water quality will be weakly acidic (about 0.5 degrees lower than the original ph value), especially from the moment the leaves start to rot! Because the decay of olive leaves releases a large amount of tannic acid, oxalic acid, humic acid and folic acid... Such substances, thus it will have a acid-lowering effect!! After the leaves are used, the water color is slightly tea-colored, very close to the original water color of wild fish. It well simulates the water quality of the original habitat, which can make the fish's body color bright and vivid without the situation of dull color. It has been used for breeding short sea bream, betta fish, seven-color fish, arowana, killifish, medium and large-sized South American fish, etc. for many years and is a kind of acid-reducing item.
