Coast to coast overflow hampers wave?

Well I made some changes, I cut about 12" out of the center of my Coast to Coast Weir. I have a plastic extension piece above the glass. I lowered this 12" piece about 3/4" and now the wave is bigger, It sometimes just flows over the original height, but just a tiny bit. Most is flowing in the center cutout. I'm liking it more now. A bunch of water changes, scrubbed all my rocks, removed as much built up detritus as I could reach and using Carbon seems to have lessened the Dino's Not gone yet. GFO should be here tomorrow, as well as a new clean up crew to restock. Some Zoa's still left, but there all closed with little strings of Dino's out their heads. Hope they can fight it and survive. Ric's have shrunk bigtime too, but the remaining ones look healthy and have color.

I would have left the overflow alone and not cared about the surface wave myself as long as you are getting motion below where you want it.

if I could get the motion along my rock with out the surface moving that would be the ideal setup.

by blocking off your coast to coast you are defeating why they were so good to start with.

you could always look at the flow along your rock/corals and see if blocking it off actually makes a difference or not.

That's just it, I wasn't getting the flow needed below the surface. AND, the amount of weir I lowered still allows some coast to coast overflow. But maybe 1/16" now with the wave, not the 3/8" it had all across the 60" length. So in essence, I am probibaly skimming the same surface as I was, Just the surface tho, not some depth like before. The center cut out handles the volume
