How to keep sand from becoming anerobic??
I cant seem to stop my sand from going anerobic and turning blue green gray, also it has taken the lives of all my neons. ph is 8.0 nitrates 0 and anmonia is 0 as well .
side note: the only remedy is to bleach the crap out of the sand and them was for days on end...
When in doubt.... SCREAM AND SHOUT!
