My 36*18*22 and stand have been completed by GLA and my Glass Holes kit is scheduled to arrive on Friday. I alsomhave the 700 gph overflow but it was looking at pacing it centre rear with 2 returns, one on each side, towards the ends of the back pane. I will use a scwd and alternate the flow through each return and supplement with my MP10.

Does this sound sensible? Any tips on the drilling ( apart from keep it slow and wet?).

Thanks!
