btw - I did try to find some articles on RidX. As is pretty much the
norm for pond advice, two recommended it and one didn't. One of the
yea's did say that it is not that effective untill the water is around
75.
=============================
It's just a bit strange why some of my ponds and tubs get this "crud" on the
bottom, and some don't. One of them never has mulm on the bottom, most have
some and that one 800g pond always has loads of it. It must have something
to do not only with the bacteria in this particular 720g tank.... but how
the water flows to the filter, the current. I'm going to try and duplicate
it in all the tanks and ponds if I can. The way the water exits the bio
filter causes a real gentle circular current - I wonder if that's why the
bottom stays so clean....... ?!?!?!?
