OK here's the problem. I have a 125 gallon partial reef tank at my office. There is close to 200 lbs of live rock in the tank. My office staff put an anemone in the tank....Ritteri to be specific. Long story short the thing died while I was out of town. We had a dead anemone in the tank for 2 days without being removed. the tank is cleaned professionally by a so called marine biologist weekly. He subsequently changed 30 gallons this afternoon with little effect to the clarity of the water. My question is: Is there anything that I can do to drastically change the ammonia in the system? I have well over $5000 in livestock so losing the tank is NOT AN OPTION. please help soon.
