Huge Red Slime Issues!!!

[booth2010]

So my 10gal (has a torch, 2 shrooms, a clown, a damsel, a starfish and some cleaners) tank has been up for a few months now, for the last month I have been battling red slime. I do 20% water changes every 4-6 days and have been adding UltraLife Red Slime Remover to the tank. When I do the water changes I use RODI water, I do 9 hours of lighting a day. Im not sure what else to do it seems to go away then one day it will be back with a vengeance and its frustrating.

Have you tested your water fdor nitrates and phosphates? Nusiance algae is caused by excess nurients. Test your phoshates and cut down on your feeding. Also do you have a skimmer?

I run my lights for about 7 hours turn back your lights lights are "feeding" the algae
