this is a nanowave 9 all in one tank and it has been running for about 6 or 7 months now. About two weeks ago i came home one day to find my tank filled with this algae. I have done extra water changes and siphoned out the algae a few times. It disappears completely at night and then a few hours after the lights are on it all comes back. The last time i tested the water everything was within its boundries....I moved all my rock to look for something dead but found nothing. The only things in the tank are blue leg and red leg crabs , some differnt snails , an emerald crab and my one piece of rock with a few zoas on it. The tank lights are PC. How can i get rid of this stuff...could my bulbs need replaced? should i change the lighting cycle?
Full Version: what kind of algae is it and how to get rid of it
anyone know?
I had that stuff several months ago for a few weeks before it went away. I dont recall the name but maybe brown algae or diatoms. I turned my lights off for 2 days and did several water changes and it went away. Make sure your water source is good.

guess i will try lights out for 2 days...and do a water change before and after the lights out and see what happens
I may be wrong, but it kind of looks like dinoflagellates 
^That
