Hello



I have 44 gal tank that I started about 8 weeks ago. It has 8 pounds of
live rock (adding more in a week) and fine sand. The first batch of live
rock I bought had sea urchins in it, I have also stock the tank with a
tomato Clown and a yellowtail. I had a algae bloom about 2 weeks ago so I
bought a Sand sifting sea star. My question is, are sand sifting stars good
or bad for a reef tank?
