i know this is gonna make biffer happy!!
i just bought a RO/DI unit for my tank, if i have any questions or anything like that about installing it, i will let you guys know, but yes, i finally got the RO/DI unit and i'm very happy, hopefully know my fish and my tank are a little bit happier. i also got another powerhead, this one is a seio m1100, so hopefully that with the other powerhead and the 2 filters should have enough water movement to not have any dead spots in my tank and help with the cyano...
