My tank is green again .I changed about 40 gallon of water with a tank I have in the back room.The tank in the back room is a 35.I added 10 gallons of new water.The 75 is turning green again, but the 35 that i put all that green water in cleared up all by its self no additives or anything in 2 days ,so I moved everything in the 75 to the 35.I'm going to try one more thing Algone I found it at Pet Solutions.If that does not work I'm going to remove all the water clean everything up and start the tank over .I have rather start the tank over now while it is still young as to have trouble later on when I have alot of coral in it .Thanks for everyones advise . If anyone has any suggestions let me know. THANKS
