Powerheads

[Tangx!]

I have a 75 gallon tank setup for about 8 weeks now. Just introduced two clown fish about 1.5 inches long and they are having a difficult time swimming. I've repositioned my powerheads and they are able to swim across the tank now but I'm afraid I don't have the circulation and may have dead spots in the corners. One Koralia 850 is in the back towards the bottom on the left shooting across the back of the rock. A second 850 is on the right side about 6 inches down attached to the side and facing towards the middle front of the glass. Neither are pointing up towards the surface. I also have a 1500gph that I took out cuz and was going everywhere. For the first year or two I'm going to have LR and fish until I'm comfortable and then add coral. Any recommendations on placement for the powerheads?

I have 2 WP25s in my 75 gallon so flow is not a issue in your tank. I have one PH on each end of my tank facing each other. Great flow and fish love it!

I forgot to mention that I have live sand too. I'm really enjoying the hobby so far!!

Does anyone know what this green thing is growing from the rock?
