Clearing Cyano

mickeyfish · 05/20/2018, 05:18 AM

Hi all,

Looking for some advice on how to clear my sand of what appears to be red cyano once and for all. Granted my phosphate is a bit high, but I have algae issues no where else and have tried both a GFO reactor and now phosguard. Any advice? I vacuum out during biweekly water changes, but it always returns. Tank is about 7 months old.

Params:
Salinity: 1.026
Ammonia: 0
Nitrite: 0
Nitrate: 5
Phosphate: .10
Alk:8.5
Calcium: 440

If you have a canister or HOB filter, make sure you clean weekly.
Add some flow across the sand.
That's certainly not a bad case by any means.
Numbers posted look good,

Welcome to a normal new tank..
Nothing needed really..
Just continue with water changes to maintain suitable water parameters..

I would stop using the phosguard/reactor and just focus on reducing feeding along with water changes to manage your phosphate levels..

phosphate doesn't have much to do with cyano. it's not an algae. It's a bacterial sheet, mostly responsive to light. If sunlight is reaching your tank in this change of seasons, that can cause you a problem. Also check your ro/di filter's output. Be sure it's zero TDS.

FYI your Phosphate level is not high.
