What Size Sump Do I Need For a 240G Tank w/ FX5?

[johnnycoolxx]

I'm planning to buy a 240G tank. I know I'll have 1 FX5 on it and I want to use an acrylic sump on it too.

What size of sump and pump do I need to make it work well?

I plan on stocking it with 1 temensis peacock bass, 1 arowana, 2 uaru, and 10 bichirs about 8" long each. And add maybe a few more medium sized fish later. Would a FX5 and a 30G acrylic sump be enough?

i go with 1/4 the size of main tank, which is 60g. But hey, the bigger the better.

I had 1 FX5 and 40g sump on my 210 for awhile...now Im running 2 FX5s and the sump. My water has been crystal clear with no problems!
