Bronze coloured powder algae??

[ckrhone]

I have bronze cloured powder algae blooming on my rockwork and gravel. I keep having to blow the algae off the rockwork with a turkey baster almost every day at the moment. Does anyone know how I can slow this down and hopefully stop it?

Thanks in advance.

PS all water parameters withing range and nitrate below 10ppm and falling. I do not think thi is the issue cos it has only just started to be a nuisance and the nitrates have been at 30ppm until fuge set up a month back.

They sounds like diatoms. In any case, any nitrates will be a problem and cause phases like this within a tank.

No. Diatoms are a natural cycle of a tank. Most tanks go through a phase where there are a lot. Once they use up all the nutrients they need, they die down. A combination of silicates, light, nitrate, and phosphate along with many other things contribute to their existence. If you can limit or emliminate any one of these things, you will be able to control or irradicate them completely. You can do this by increasing your tank husbandry, water changes, limit the amount you feed, have a smaller bioload, etc.
