green hair alge

[tony varrell]

My aquarimum is getting some green hair agle blooms. i am not sure why. Flow is strong you can actually see the stuff being pushed around. All water Parmeters are good as usual. This is a very mature aquarimum. How do I get rid it the pest naturally??

have you tested for po4? what type of water are you using for water changes? by good parameters you mean..?

I do 15% water changes once a month with marin tropic salt. The water is filtered through a RODI system. I am not sure what po4 is? This alge is on one of my Tunze power heads and and 3 blooms are on the base of some SPS. It dosen't seem to be getting any worst. It is just there..

PO₄ is phosphate, a nutrient for algae. A phosphate reactor might help with the hair algae. That's a common approach. If the alga is easy to reach, pulling some of it out will export nutrients, too.
