Be patient, your tank is just getting started. The way I combat cyano is to
have good pump / current blow just over it to pull it off and float away
and eventually goto the PS. But since your sand is just started and want
good current close, you may get a sandstorm instead. Cyano will come and
go, even in mature tank that have slow flow or deadspot. PS is the main key
to remove nutrient, lesser nutrient the harder algae [any type] could grow.

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].
