when i put the substrate into the tank originally, the water cleared with

my tank with CO2, water changes and very soft water, that SOMETHING is
clouding the water, slightly so but i have had others view the tanks and when

My filter maintenance (eheims on all the big tanks) is consistant with my
other tanks and all are similar with the exception of the substrates.
Perhaps it is this one manufacturer, processing plant, whatever.
But the tank was EMPTY when i added the substrate and all of the plants,
driftwood and rock had been in other tanks here in Milton for several years.
But IMHO the substrate, unless using the Dianne Walstead Methodm is the
single most UNIMPORTANT component of a planted tank. If whatever is used is
pleasing to the eye of the aquarist, then THAT is what should be used.
