filter choice for new 75 gallon

[phenagain]

I've recently started back in the hobby after a 20 year hiatus. I just got a 75 gallon and I was hoping to add a severum, red tailed shark and a few gourami. I currently have 2 sponge filters running but I'm guessing that may not be enough for these larger fish?  

Do I need a HOB or canister to handle the waste better?

2 sponge filters is probably good.

I ran 2 Tidal 75s on my tank.  I also ran it with one AC110.  I would recommend two (AC75s will not work without modifying the rim).  just because of the flow balance or side mounting the intake/spraybar to run the length of the tank if you use a canister.

I honestly would recommend a canister as long as you commit to cleaning it properly!  Sponges work too if you prefer those, I would just have a decent air pump.

RTBS enjoy flow in my experience.  I've had them on pretty much everything. Even if it's just a bubbler, something for them to play around.  They hover a lot, swim through things. Having a scape where you have a lot of different hides/cover is going to be beneficial to reduce the stress of the fish.  Because that's their nature, higher flow helps to keep the water moving when it is covered.

Thanks for that. I got a power head as well. More places to hide is something I definitely need to add.
