SRC Member Tanzy Posted June 24, 2004 SRC Member Share Posted June 24, 2004 Sounds like cyanobacteria. I guess the tank must be overstocked and have very little water movement.

SRC Member typrobin Posted June 24, 2004 SRC Member Share Posted June 24, 2004 confirm cyano ah....use a powerhead to blast your sandbed permanently... otherwise, use a few powerheads to create more water circulation as advised be tanzy...

giantbicycle Posted June 24, 2004 Share Posted June 24, 2004 use rowaphos/contra/biophos to lower down your P04...as it may be the cause..less feeding , lesser photoperiod too Quote Link to comment Share on other sites More sharing options...

SRC Member Acanthurus pyroferus Posted June 25, 2004 SRC Member Share Posted June 25, 2004 bro. just do a major water change , add Rowah or Bio Phos and circulate your water well and all the cyno will go away..... Quote Link to comment Share on other sites More sharing options...
Navyblue Posted June 25, 2004 Share Posted June 25, 2004 Yup... as long as one of phosphate or nitrate became a limiting factor it will go away. Did you test for phosphate and nitrate? What I do is to use my fingers to crush the layer everyday and prevent it from forming a film (sounds crude I know), the same theory as using a powerhead but IME the power head will create some unsightly holes hehe...

Alternative method, buy the 3ft fork thingy from the LFS and disturb the sand once in a while (like 1 to 2 weeks a time). *Note: Make sure your skimmer is working and filter media is clean before you do that as all the "@#$%^&*" will start floating in the water.

JuzzMarine Posted June 25, 2004 Share Posted June 25, 2004 I may be wrong....... Last time when I use 10K PL tube over my tank I always got cyno and diatom all over my sand bed. Ever since i switch to 14K MH, the cyno is gone, though diatom exist, but minimum. Can I conclude that higher color temperature prevent cyno growth? Or is it bcos of MH that do the wonders?

Generally speaking, the bad algaes prefer lower colour temp. Better one actually prefer bluer light, like coralline Quote Link to comment Share on other sites More sharing options...
