I have a 20 gallon high tank. about 10 lbs of fiji live rock and using live sand.
I had gotten a very bad outbreak of red slime in my tank before I really had anything in there. I had a clown fish and 2 small hermit crabs. I went out and got a power head and put it in there and only used the light for like 3 hours a day and went and got some RO water and changed 5 gallons out. after about 3 days all the red slime was gone.
about 3 days later I added some yellow star polyps so I kept my lights on during the day now. as soon as I kept the lights on I started getting small bits of red slime all over the tank. I got a new toothbrush and cleaned it all off and the next day its all back. now if I clean it in the morning when I come home from work for lunch 3 or 4 hours later its all back again.
I am moving 300 gallons per hour with my filters, I have filters mounted on the back, not a canister filter. and I am moving 400 GPH with my power head. and I got the power head that you can mount anywhere in the tank, it has a magnet to hold it in place. so I really cant see how it could be a flow issue?! there is even some red slime growing right on the spot where the water from the power head is hitting!!
what else can I do to get rid of this stuff??? today I got some stuff that is supposed to kill red slime but I know it will be back once I stop adding the stuff. what else besides flow issues could it be? I only got the chemicals to kill it because it was growing on the stalk of my star polyps!!! I want to get rid of the underlying issue, not just treat the symptoms.
any help would be GREAT!
Thank you all VERY MUCH!!!!!
