Need Lighting Help / Suggestions

[DiverDude]

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.
