Just a note to differentiate to those who do not understand the difference
between a deep sand bed and a ornamental sand bed (which I use). With a
deep bad you have several inches of fine sand used as part of the
filtration system. I use less than a inch of crushed coral (much larger
than sand) just so I don't see the glass bottom of my tank. There is
little to no filtration properties to it. I do siphon this every time I do
a water change to get all the gunk out that falls into it. With a deep
sand bed you don't want to interrupt the anaerobic organisms deeper in the
sand bed.

So, in short:
deep sand bed: no siphon
thin sand bed: siphon

That is correct, we don't siphon the sand. You can try to gently get it
back into the water during a water change, or rely on livestock to turn
over the sand and keep the surface clean.

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].
