UV sterilizer: will it help limit surface scum?
Will a UV strelizer help with surface scum? No matter what I do, I get a
pretty thick surface scum by the end of the week. Also, how does one decide on what size UV sterilizer to get? Any specific recommendations for a 135 gallon tank? Thanks in advance.. -Bruce Geist |

UV sterilizer: will it help limit surface scum?
Thanks Leigh..I very much appreciate your response.
Surface scum is not a huge issue for me, since I have a rather large canopy that disguises it. But it would be nice to do something to limit it. Surface current is probably the only way then.. Huh. I am not concerned about CO2 loss, since I use a controller. In fact, I already have three powerheads with low output, (~30 gph) to try to move the surface a bit. (My tank is 135 gallons.) However, I may try a slightly more aggressive flow. I am a bit worried, for the following reason. Near my filter return, I tend to get blue-green algae every now and then. It only appears near the filter return, and does not spread beyond that immediate vicinity. I have come to believe that this may be due to my (low) nitrate level and the fact that blue green algae can extract nitrogen from air. (What is your perspective? Ever see this problem?) Now that I am actually testing nitrates however, I am not so sure.. my nitrates seem to be smack dab in the middle of the desirable range-- i.e., after a water change they are about 3 ppm, and toward the end of the week, they creep up to somewhere near 5 ppm. Should I be shooting for somewhere near 10ppm? At any rate, my worry is that if I put more surface current, maybe I will get significant blue-green algae problems. What do you think?. Is there something else going on here I am not picking up? With my nitrate levels where they are, I am not intending to do much supplementing. Right now, I believe potassium is my limiting nutrient. I am adding more of that per week in addition to TMG (and have always added TMG). If my nitrates sink really low with the addition of the extra potassium, then I may supplement with nitrates. Sound like a decent approach? Perhaps that will eliminate blue-green algae outbreaks all together. Does anyone know if potassium shortage is linked to blue-green algae problems? -Bruce |

I had the same problem, but I got a small surface skimmer that fluval makes.
I costs about $10 so its rather cheap. It simply plugs into your hose on the canister intake, and continuosly skims the surface for any debris and scum, sucking it into the canister filter where it is consumed by our friends the bacteria. I've had it for about a year now, and never had any problems with surface scum or floating debris. I'm sure there are other manufacturers of similar products, but so far, I've just found this one. And at $10, I'm not looking any further! :-) Good luck! /Mathias "BruceKGeist" skrev i meddelandet ... Will a UV strelizer help with surface scum?
