Folks, you won't believe this, I still can't! I'm the one that was almost about to quit due to an alge bloom that was kicking my butt. Well, I took alot of advise and with some time, patience, and work, my alge was GONE! I had put in a large clean up crew and my alge, all of it, was gone in a week. I was just about to start putting in a couple of new corals and hadn't gotten to the lfs yet. I came home for dinner and the next thing I know, KABOOM!!!!! My beautiful 92gal corner bow tanks bottom gave way all at once! Water, glass, sand, live rock, critters and two fish on the floor, furniture!!!! I'm heart broken. Before anyone asks, I'm not aware of any rock that fell and I hadn't been in the tank for a couple of weeks. I had a 3-4in sand bed so if something fell it should have been cushioned. All the time, money and work, down the tubes.
