Skadwick Posted August 30, 2009 Share Posted August 30, 2009 Tested my water this week after seeing some strange algea growth and was shocked to see my nitrates had spiked to around 30. I have changed about 40% of the water in the tank this week with 3 water changes and have been picking out algea almost daily. I want to know what could have caused this spike, how to drop my nitrates back down, and what kind of algea is this (is it killing my corals?) ANY help will be greatly appreciated. Heres pics of it now. I know the algea in the last two pics before the FTS is red slime but im not sure if that is what the longer stringier algea is on the corals. Please help! Link to comment
spankyleatherlips Posted August 30, 2009 Share Posted August 30, 2009 perhaps check out the Ultimate ID thread . I am no expert and am new to the hobby. Just wanted to try and help. Or the Pest and Disease thread. Link to comment
The Nomad Posted August 30, 2009 Share Posted August 30, 2009 looks like diatoms. They'll go away on their own. How old is your tank? If it's not fairly new, then it's cyno. edit- I think it's cyanobacteria Link to comment
Skadwick Posted August 31, 2009 Author Share Posted August 31, 2009 I posted in the pest and disease thread...it was IDed as cyano and they said possibly dinos. Link to comment
Nanzo Posted August 31, 2009 Share Posted August 31, 2009 if i were u, when u do a water change, try to siphon out as much of that cyano as possible. check water parameters and make sure their all on check. sometimes cyano outbreaks r do to lil water flow in areas because detritus might build up in some spots and cause nitrates to go up. my 2 cents Link to comment

And its weird one of the big patches of cyano is in an area where all the sand was blown away by my ph cause of the flow. Link to comment

And its weird one of the big patches of cyano is in an area where all the sand was blown away by my ph cause of the flow. thats what probably caused it. theres alot of detritus under the sand and when the powerhead blew sum of the sand, it caused the detritus to spread around your tank. id just keep up on water changes and if it doesnt change and only gets worse, try chemi clean. reef safe stuff and got rid of the cyano outbreak in my tank. but this does not solve the cyano problem. just make sure u have everything on check and it should go away. good luck.
