Thanx for replies.
Then noone is siphoning the sand bead?
I do have 3 inches of very fine sand. If I increase the flow it will lift
the sand from the bottom. But I see the problem both in the higher flow
parts of sand layer and lower flow parts.
Watching it from the front I can see the line between aerobic and anaerobic
layer. Anaerobic layer is at aprox. 1 inch deep.

I dont Run sand, Glass bottom is the way I set up, But from what Im seeing
here almost every one does.
and in the tanks that its set up correct , it looks great.
Is the sand bed your talking about deep enough? If not it will kill you in
the long run!

My tank is 3 years old. It is 150 g with DIY downdraft skimmer with iwaki
50 rlt.
I constanly get diatoms and cyano all over it. I can hand shift the sand
but cyano is in one day back.
On the live rock I don't have any nuissance algae, only coraline. Corals
are growing, mainly softies and lps but also two sps corals

Hi,

I'm wondering how is everyone here maintaing the sand. I have problem
with it, it constantly gets algae growth over it. First diatoms, then
cyano. I have very fine aragonite based sand.
Is anyone sifoning the debris from sand or shifting it and how often?
Any other methods?

tnx


As Marc stated....
Your sand will stay as your tank mature. The sand will get slimed and
will be weight down [eventually].
