You should NEVER put sand under rocks, most new hobbyist's do it. - Its not a MAJOR issue, but over time it can become a problem. - What you will want to do is try and siphon as much detrius out as possible. - You dont want it messing with your water. - When you replace the sand, try and dig as much of the sand out from under it as possible. - Just think if a goby gets in there and starts digging around.... Just think if he digs enough out it could cause your rocks to crash down... but on the other side it will let loose alot of bad toxins
how long has your tank been up and running?
- Me personally...
I would remove all of your corals. -
I would remove all of your rock.
Siphon the sand. - Push it all forward in the tank...
Place the rocks back in without sand under them.
Then place sand around them.
Then I would take out 25% of the sand.
But really to be honest... the brown layer your talking about is most likely from phosphates, or to much light.
can you fill me in on your tank?
