I'm pretty new to the hobby. I have a 140 gallon which was professionally installed two years ago and has been maintained since. I'm starting to manage myself because I really like the hobby and find it fun and challenging to manage my own tank. I've had high nitrates since tank inception, typically around 40-60 ppm. I put in a chaeto fuge about 3 weeks ago and from what I've read it's too small to significantly reduce nitrate and phosphate but it also serves as a pod breeding ground. I started dosing NoPOx but had a bacterial bloom that killed my yellow tang so I'm really leery about trying that again. I've read some reviews on Polyp Labs Genesis Rock product and am wondering if that would be safer. It has a ceramic brick which goes in the fuge and the genesis product which is a mix of bacteria formulated to control nutrients. I'm thinking this may be safer because the bacteria mostly stay in the brick and don't create a massive bloom in the tank. Any thoughts about this particular product or generally bio bricks vs. carbon dosing.
