For those of you with cloudiness problems, here is something to try:
Put a handful of the substrate in a jar and add water. Dump the water in so it really makes a mess. Then let it stand. No stirring or anything.
How fast does the water clear? DOES it clear?
If it does clear, shake it up again. How long does it stay cloudy?
Here is my concerns:
MAYBE MAYBE there is something besides particles getting stirred up by the filters in these tanks. I do not know, but MAYBE there is some sort of interaction between the water and the soil. Some chemistry thing going on. Perhaps related to the pH or the mineral level.
Alternately, perhaps you are seeing a bacterial bloom, that is growing and sort of overtook the substrate-clouded water. The tank was cloudy for a day with dusty substrate, but then the heterotrophic bacteria grew, and now you are seeing that as cloudy water, but since it looks the same as substrate-cloudy water you are not sure which it is.
