In short, three two inch drains and two 1.5 inch returns should do nicely.
what size return lines for 600 gallon tank

Thats what I am thinking, I already have alot of 1.5" plumbing I can use on the returns just need some 2", Just worried the drains will be too much for my 3 55 barrel system, it has 3" pipe connecting them, I think im going to add another on the sides with 90 elbows as I can't add any more in the front
What type of hole saw did you use to drill the holes? I know there is one for glass and one for wood
Doesn't the drain have to match the flow rate of the return? Won't 3 2 inch drains generate more than 7500 gph...
The drain just has to be larger than the return. It will only drain as much as it needs to in order to keep the water level constant.
Hopefully it's okay to revive an older thread here. I have a 7' long 420 gallon tank that I'm putting together with a reeflo dart/snapper gold hybrid return pump that has a 1.5" diameter outlet. I drilled 3 return holes (each end and middle) that are only 3/4" because I was planning on using loc-line. Thoughts on this design?
Not quite sure what loc-line is but 3 3/4" drains won't be enough. I had 2 1.5" drains on my 300 and have 3 2" drains on the 600. Is your tank plywood cause you could drill them bigger, I would go 1.5: with a valve to reduce the flow if needed
