kool. dont stir it. its bad. got it. ok so heres another question. i may be taking down a smaller 12 gallon thats been running about 7 months. can i take the sand and rock from that and add it to my tank without causing a catastrophe?
I stir my sand bed once a month or so...NOT a lot, just alittle around the glass
When i do this, all the filter feeders seem to have a field day....and it cleans the glass that has built up algea/etc....
I thought it was good to mix up the sand bed alittle, and get all the junk out of there.
My sand bed is generally 3-4" deep.
If your system is designed to utilize the sandbed for nitrate reduction it is a bad idea to stir it. If it is purely for aesthetics then it is a good idea to stir it. BUT, if you have not stirred it for a long time, it i best to leave it alone.
