Need Lighting Help / Suggestions

[Slick Fork]

I don't really buy into the theory that lights "Cause" algae problems. Algae issues are caused by excess nutrients, if you don't get the nutrients under control you can change lights all day long and it won't make a difference, you'll still get algae.

I agree. There *have* to be excess nutrients in the water for the lights to do anything. I've been chasing that dog (unsuccessfully). I do WEEKLY ~20% water changes, all my parameters are bang-on and I have a light bio-load and I feed lightly so I don't know what else to do.

I may be chasing ghosts here but I've seen a few tidbits of evidence that indicate to me that my lighting is not helping the situation.

Phosban may well help but the damned stuff is expensive and I don't have a very elegant way of running a reactor with this setup. Besides, phosban is just masking the issue of excess phosphates anyhow. I'd prefer to get to the root cause.
