ok phoned hollywood today to try and sort out a couple of loop pumps for my new tank.
well when i said i wanted 4 holes in the bottom of my tank with bulkheads they said HOLES BOTTOM OF TANK NO NO :oops: just put some power heads or a pump thats going to push the volume of water you want,hmmm so do i do this now or stick with me 4 holes.(hasnt been built yet so still safe)
