Filtration options for a 90 g tank FOWLR

[kenny5130]

I have a 90 g tank and two big HOB filters, an Aquaclear 500, and a big Penguin.
I know it has a lot of water movement but would I need anything else like a protein skimmer ? The tank is not drilled. I plan to keep two butterfly fish and a number of smaller fish.

Not really.. As long as your removing as much detritus as you can on a regular basis you should be fine IMO. Adding a skimmer definitely wouldn't hurt though.
