Reefing newb
As some know I am about to embark on my first reef tank and went and bought a 1 1/2" bulkhead( 1 3/8" id) for my drain. I bought it at one FS that said it should be fine. Then while out looking for some other parts being one store doesnt have everything I need the next LFS said that my drain would be too small and suggested that I get a larger bulkhead and thus a larger drain from the tank. I now also have a bulkhead with an id of 1 7/8". With a 65 gallon tank and using a 40 gallon sump what would be an adequate drain. I was going to use a 650gph return pump to move the water back up to the tank. I know everyone has their opinions, so I ask what is yours?
