It's amazing to me that if you do not have a working knowledge of the plumbing mechanics of a larger aquarium, how confusing it can be!! I've spent the last month or so reading as many forums as I can trying to get this straight before I buy the necessary equipment, but I'm just not there yet. My question is still this;
180 gallon tank, 20 gallon long sump, Aro and a 1/2 dozen small (4"-6") SA cichlids, okay question(s)-
1) Do the overflow box gph and return pump gph have to be the same?
I'm looking at an CPR or Eshopps Overflow of about 1200 gph. Does the return pump have to be the same or a little more?
2) For a 180 gallon, should I be using a 55 gallon sump?
Some postings talk about not being able to get the flow rater right. Is more gph better because of the greater turnover of the tank? Should i be reaching for a minimum turnover per hour? Is 1200 gph sufficient?
PLEASE!! This thread will have 75 reads by tonight, but only 1 reply. Please let me know what works or didn't for you. I hate to order the equipment only to find out it's not going to work! For the people that have a 150 gal-200 gal, what are you using? If there are other variables needed to answer this question (ex: head height) please let me know.
