New to me 90 gallon

[Stramn]

Okay guys, I got a new to me 90 gallon tank. It used to hold a gator, but since I bought t, its getting overstocked with Cichlids. I'm in need of some serious input on how I should filter this bad boy, what decorations to use and substrate to use.

Here is a pic!

Substrate is your choice, I personally go barebottom for easy cleaning. As for filtration I would run atleast two filters. Hang on backs or canisters it's up to you. Some good filters are aquaclear, Rena xp, Fluval, and Eheim. What's your stocklist? That would help us in deciding what filter is right for your setup.

Could I use a pressurized outdoor pond filter on it? or would that be a bad idea?
