flocculating agents for cloudiness
Can anyone suggest some agents which could be used to flocculate (form
into clumps) fine suspensions of clay in aquarium water?
People who've had trouble with laterite or clay cloudiness have
sometimes tried very fine filters without success since the clay
particles can be under 2 microns in size.
When I've had troubles with cloudiness after uprooting plants, I can
often clear it by running an dirty floss style trickle filter like the
Whisper filter. Of course the tiny particles can easily pass through
but the bacteria and sludge which accumulates on the filter seems to
attract the particles and clears it up nicely. Is there a
chemical/biological explanation for this?
I've also heard Paul K suggest adding a bacterial culture to the
water. I think someone else suggested calcium or magnesium carbonate.
Would these work?
