I'd add more rock to the sump and the tank to achieve about 1.3 lbs/gallon. Your gross volume is 72 + 20 = 92 gallons. I use a general rule of 1 to 1.5 lbs LR/gal. Compromise is 1.25 Lbs + just a little bit more. Hence my 1.3 lbs suggestion. You'd be hard pressed to get 45 lbs into the 20g sump so I'd put some in the main tank also.

As for the Bio Balls...I've never used 'em and don't know much about 'em, but I "hear", recently, that they are nitrate factories. So, ya, I'd ditch those in favor of creating room for LR. LR is an excellent nitrifying filter, the more (to a point) the better.

JMHO.

Cheers,
