Need help regarding red algae growth

[Anirban]

Hi everybody,

Can anyone please tell me what are these ? Looks like red algae but the growth rate is quite high and how can I control these?

 

[kbourque]

It looks like cyano have you done any testing lately?

 

[kbourque]

And how old is the system

 

[Anirban]

Its 3 month old and parameters like nitrate-0 and phosphate almost 0. Calcium near is about 150 ppm and salinity 1.025. This started 4-5 days back. I tried changing water and dosing with red sea NO3 PO4X. The ph is 7.8.

 

[kbourque]

Could be because your nitrates hit 0 I had a green cyano bloom not long ago when my nitrate hit 0. Are you running any bio pellets or carbon dosing? Do you run gfo?

 

[Anirban]

No, I dont run gfo. But I have activated carbon in my filtration unit and I changed it a week back. Do I need to worry about it or is there a way to get rid of it?

A+ on cyano.

 

[kbourque]

Well I would try to bring the nitrates between 0-10 since you are going for Lps. Lower your lighting schedule will help to get rid of it try 4 hrs a day. I wouldn't expect it to go away quickly. And are you doing weekly water changes?

 

[kbourque]

I think feeding less will get rid of it also along with a shorter lighting schedule. It is bad algae will take over everything if you don't take action against it.

Red Cyano.

Water chemistry will have to be checked and corrected. For the short term and instant kill,

@kbourque
I sucked out large part of that cyano and also reduced the LED intensity. Also as suggested by ReefMadScientist I ordered some chemiclean. I tested the phosphate level in my water and saw a sudden increase in phosphate level so yesterday night added some alcohol (approx. 2ml for my 30 gal) to lower the phosphate. I will keep you guys posted about the progress.....thanks

Hi guys,
after a week long war finally got rid off all cyano. Cleaned the tank and added chemipure in the filtration. Chemiclean worked like a charm and all my fishes and corals are really happy now. Here is a picture of the current tank. Thank you guys for all those help.
