Hello friends its about one and a half year ive set up my ref.But since then i havent even take a look on it.
Now My tank has a problem.
I wanted to know if a ref sand need to be siphoned or not?
The matter is that cyano bacterias are bothering me.
I dont know whats the matter.
Every thing was ok last 3 months.
But little by little they came to the scene.
3 of my corals were destroyed although every thing was running the same as 3 months a go.
Water parameters are good no3 10ppm,po4 about 0 ca 440 kh9.5 (dont know the mg but think it must be ok)
How deep is the fuge bed? Don't mean to contradict. But if its less than 3" I personally would vacuum it carefully. In that case there is not enough microfauna or anaerobic bacteria to complete the nitrogen cycle. 3" or more with no sandsifters or fish and I would leave it be. My personal opinion. Nothing more
I personally would vacuum carefully so as not to cloud the tank too much. Once every week or two. But I'm not suggesting you do. Thats just what I would do. Maybe try to inceease flow first and see if that does the trick
