Does anyone know by experience or solid information whether or not adding blackwater extract to my larger tank would be beneficial? You can see the list of fish in my signature. I bought both Tetra's version and Instant Amazon for my Arowana. I have been thinking about adding it to the cichlid tank. I doubt it would really cause any problems for the SAs but I worry (its a longshot) about maybe stressing or adversely affecting the CAs somehow. Would this be a bad idea? If it's not a bad idea, would it just not prove beneficial enough for me to keep wasting my money on? Also, I bought a bottle of Ketapang Vital (made by same company as Instant Amazon) because it had a picture of an Aro (not Silver) on it and I might have been too blazed to actually read it thoroughly. I think it is basically the same concept as Instant Amazon, except for the Asian lakes and rivers. I have been adding this to my Aro tank as well as the amazon because I figured at the very least it has vitamins and other beneficial ingredients in it. Anybody with info I appreciate it and Happy New Year..
