Algae on coral

This algae has gotten a little thick on my Polyp and wanted to know what I can do to get rid of it. The polyps havent opened up in a few days where it is pretty thick.

Picture attached.

 

Well, I would first try to blow it off. Are they GSPs? If so, you can take a soft tooth brush and scrub it off. That shouldn't hurt the coral. If not, what are you parameters?

 

Hey Sinny C

in a 12 gallon tank no more than 4 inches of fish would be ideal IMO and with 3 chromis and a clown, I think you are possibly over the stocking level

this is important as the waste products of that excessive bio load are what is making your algae problem worse

are you testing for Nitrates and phosphates - ( even if you are and the readings are perfect, the Algae tells me, that both are present and being used by the pest)

If this where my tank , this is what I would do

1 - remove 1 of the chromis
2 - remove some of the algae at next water change using a toothbrush or fingers and then syphon out
3 - blast the rock with a turkey baster or power head to remove any detrius that is blocking the pores
4 - incorporate some Phosphate removing and Nitrate removing products into my filter system to reduce the nutrient levels and starve the algae out ( Purigen and Phosgaurd by Seachem both work IME - as does Rhowphos , but there are others I am sure equally as good)
5 - check my lighting as aged bulbs or bulbs with poor colour temperature (K rating) can also encourage nuisance algaes

thats what I would do if it where my tank

others may offer different courses of action

Tooth brush worked like a charm, came right off. Thanks a million!

 

Steve, all great suggestions. I did a WC today and was able to remove some of the algae. My readings are almost spot on so I think you are correct on that. I will do the following and let you know how it goes. Appreciate your advice.
