I have a 90 gallon with a Fluval 404. It also had a Hagen 402 power filter but in fiddling around with that, it seems that I have broken it. I've had the tank for maybe a month now and received it fully cycled with two fish which are a small clown loach and an opaline gourami. I also have 3 platies and some mystery snails and thats it. Hopefully I'm OK with having just the Fluval running until I get something else. Ultimately, I'd like to adopt out the loach, get some angels, a school of rummynose tetras and I haven't decided beyond that. What do I need for additional filtration? I would like the most quiet running option please.
