It is a fowlr
now, but will be a reef hopefully soon. Mine is a 72 gallon and the pump based on the head loss calc in reef central, seems to be pushing at about 1000 gallons about an hour. I guess I am pretty close.
T-eeing the excess water back to the sump is a good idea, although I would hate to cut the pipe again. But thats what I said the last 15 times or so...
One another question that I have is that the pump seem to be putting tonnes of micro bubbles in the display tank. I noticed there were leaks in two places in the plumbing. I am going to seal them with teflon and run the pump again to test.
Can there be any other reason other than the leaks, that would cause microbubbles? I dont see any bubbles in the sump.
