Hi all. I have a 75G tank with a 20G sump. I'm ordering the Jebao DC
-6000 which is adjustable up to 1580. (I know this is overkill but it is adjustable) I have a 1500GPH overflow box from glass-holes.com. It's drilled and we put it dead centre on the back of the tank. (Didn't plan out the return at the time)
I'm ordering 3/4" overflow kits now and I'm trying to decide if I should split the return line and have two return bulkheads and flare nozzles, one in each corner, or one on either side of the return.
So my questions for you are:
1) If this was your tank would you split the return and have two bulkheads with flare nozzles? How would you position them?
2) If it was your tank and you went with just the single return with one bulkhead and one flare nozzles where would you position it?
Also please explain why you would prefer one or the other so I can understand and weigh my options. Thanks fellow reefers
