I went with a closed loop system. I have a 1500 gph pump that sucks water in from two spots in the tank and returns it via 4 spots. I posted pictures of it a while back. I like this method a lot, no powerheads, less cords and the tank seems tidier.

Yeah mate I really like this way of gettin circulation as long as the intake grilles are not too tight to be clogged all the time and not too apart to let him get in. Not sure an intake like tights would be a good idea here. Not pretty either!!

Only thing is, is that ive no room above tank for pumps to do this :confused: have to think about it, whic is all i can do at mo, no time to continue my set-up and manage tank properly at mo. doin my head in!!!

Yeah mate ive got similar... return at high level one (RHS) and then tank is drilled on other (LHS) at bottom with a weir in front, but i reckon there should be more flow than just that.


Nice one

im going to be using an external pump that is going to pump water into the top front left side of the tank and also the back bottom right to get a good circular flow the t for the split will just be at the top of the tank that way if the power goes out the tank wont drain. also i am using 1 inch return piping... i figure in a 75 g that will be enough flow for the octo along with 2 overflows
