Interesting comments about flocculation. When I was at my favorite fish
store the other day to buy gravel, the owner gave me an instruction
sheet and a plastic bag partly filled with an iodine-colored liquid she
called a flocculant. She said the purpose of this was to cause small
particles to collect and either drop out or be filtered. Apparently even
after a good pre-cleaning, gravel has enough "stuff" in it that some of
it will suspend in the water.
Not sure what the liquid was, but it sounds like a good thing to use to
remove suspended clay particles floating in the water.
But for sure, it did *not* remove the tannins from the new piece of
aquarium-approved driftwood I stuck in the tank the other day. Nice
reddish-tan color that I hope goes away soon.
