Please Help..this algae is taking over

[sduerk]

I have what appears to be red slime algae that is slowly taking over my tank. I noticed it around 4-6 weeks ago and consulted the LFS about it. They tested my water and it showed high phospahates and otherwise pristine water conditions. They suggested I decrease the feeding and do several water changes. I have since changed 5-10% three times over that last couple of weeks and have decreased the feeding to once every other day. When I do the WC I also siphon out as much of the algae that I can. Nothing has helped...what can I do????

You can use phosphate sponge to lower the phoshates.
But check your source water for phoshates also. If your water contains phosphates/silicates you may never get rid of the red slime as you constantly feeding it.

my source water is distilled water from BiLO a local grocery store. So i know it is pure water.

It's maybe pure, but still contain phosphate and silicates. Pure doesn't mean 0 phosphates and 0 silicates, though!
