I have a 29 gallon hex tank that for the last 3-4 months has had a red slime issue. It doesn't grow on right the sandbed, it grows along the glass and right under the top of the sand... Sometimes its not all red, it can be pink, green, or blue...I am assuming it's all forms of cyno. I have 3 power heads in the tank with a HOB filter so I don't think circulation is an issue. I actually have water being forced into the areas of cyno. I only have a few sand sifters, not sure if that will help as it is right on the edges. My nitrates are 20 ppm or lower. Would my lighting have anything to do with it? It's just one of those junky fluorescent lights (for now). I would think it would have no negative or positive influence as far as algae is concerned. The areas that have cyno do receive sunlight. Is there anything I can do to stop the cyno? I do 10%+ water changes per week. I also siphon as much as the cyno possible... I try to feed only once a day.. Bioload is pretty small... CC star, pincushion urchin, 2 false perc. clowns, six line wrasse, plus my CUC... On a good note, even with the fluorescent lighting, I am growing small amounts of coraline algae.
