Ok I have changed the flow in the tank and it seems that there is more flow in the areas there was not, but there are 2 problems that I have run into with this. 1 which I am trying to figure out with the Help of Corey, since I put the bigger pump back in the sump for the DT, my dreaded Micro bubbles are back which is confusing me to no end, because the pump is fully submerged in water. I have check and there are no excess bubbles getting into the return section of the sump. It is just baffling why this is happening. 2nd thing is I have a pissed off Hammer coral, it was doing fine and nice and full, but since I have changed the flow in the tank it has not fully extended. It still looks good but just not out and as full as it was before I changed the flow in the tank. I want to know if I should move it to another spot in the tank to see if that will make a difference with the extension on it or should I just leave it alone and see how it does over the next few days. All the other corals in the tank seem to be doing fine and are happy.
