Well I finally installed a spray bar in my tank. I used 3/4" flexible PVC (found in the irrigation section at Lowes) and drilled about 10-12 holes (1/4" bit). I put some of the holes facing directly down to get some flow behind my rock work. The remaining holes were pointed toward the front of the tank in random areas. I am very happy with the additional flow I am getting combined with a 3/4" Sea Swirl fed by a mag7 from my sump. I think it blends in pretty well with the black background. I will try to get some better pictures of the spray bar installed this afternoon!
