125 gal 6ft growout tank---> How many 1" overflows.

[Milo2]

I just picked up a used 125 gallon tank that I will be using as a bb growout tank. I have several 1" jehmco overflows. The plan is doing a smaller version of Discus Hans racks. I plan on using a 55 gallon sump that I purchased thru the dollar per gallon sale. I have not purchased the return pump yet but was planning on getting the Rio 32HF. Which will run around 1000 to 1200 gallons per hour(includes head height). In the sump will be just like Hans' with the poret wet/dry foam.

Please any advice would be much appreciated. Any suggestions or changes especially before I start to drill the tank this weekend.

Will 3 1" bulkheads be enough for the overflow?

Rio 32 is way too much. If you re looking for 1000-1200, rio 20 or 1 lower is good.

id say 2 1 inch is more then enough. the standard 125g from aga comes with 2 1 inch drains, and even with a mag18 and minimal headloss I had to adjust the durso stand pipes for excessive air
