Nasty Spot Algae!!
 

Just wondering, what is the best way to clean spot algae of your tank and to keep them from coming back? I have a 40 gl tall tank with about 30 gallon of live rock and 1 inch sand bed. My water paremters are where its suppose to be i get it tested everyweek. Tanks been up for about 2 months but technically the water and live rock and sand came from an existing established tank. I have 2 power compacts 30'' one 10000k and one actinic. Not worried about the sides and back wall but i'd like a clear view of the front. The sides and backwall is actually getting covered with coraline which i heard is a good sign but the front is also getting coraline which i'd also like to remove. So guys whats the trick to cleaning this spot algae off?

thanks

oh also all i have is one sifter some hermits and snails and some easy corals like pulsing xenis and zoas

Great question. I use a magnetic algae scrapper to remove brown algae from the front glass. Coraline algae is best removed with a razor blade.

yeah the brown algae comes off no problem with the magnetic scraper but doesnt even touch the spot algae

spot algae is annoying me so hard to clean

if coraline algae is on the glass and you srape it off , is it still going to spread?

Yes it is going to spread. It will spread over the live rock and back glass.
