Spanko as mentioned above it is a 10 gal, 3 watts of pc lighting per gal, been running for 4 yrs now. I use an aqua clear filter.
Tried a larger filter but it did not go over well in the tank, also tried a powerhead the smallest one and it was just to strong. My best success has been with the mini filter so I won't change that again.
I position the filter is the flow hits the middle of the tank and movement goes to either side of the tank gently. My corals are not blowing around the tank but gently moving.
I think I will give one a try, they are so pretty.
Thanks for the replies and opinions......
