I have a newly cycled and set up 40 breeder with a couple clowns so far and they hangout in a dead spot right above one of the wavemakers. I did some research a while back before buying, but am now second guessing myself that I bought some that were too powerful. I'm currently running with x2 Jebao OW-25s on the slowest and least powerful setting on opposite ends of the tank. There are no dead spots, but I'm unsure if I should downgrade to x2 Jebao SOW-4 or not. I could just be in my head with all this too . Eventually I'd like this to be a Softie and LPS dominant tank.
