sand

[stwalkden]

I'm planing to set up an amazon bioype tank in a 33 gallon tank. I have 2
aquaclear filters on this tank. I would like to a sand flourite mix as a
substrate, but am concerned about the sand getting into the filter
impellers. Or I can go with natural (uncolored) river gravel. I plan to have
40 watts of flourecent lighing, mainly swords and dwarf sag. Any opinions?

Sand and Flourite will separate over time-particle size, shape and density are
much too dissimilar.

River gravel which has a similar particle size to the Flourite will probably
stay mixed for a while.

100% Flourite will stay mixed forever.

I have pure white Florida beach sand in my tank. It's about as fine as sand
gets, and I have no problems with it getting anywhere.

The big thing to remember is not to seed it too deep, or a stinky, rotten,
anearobic layer will eventually develop under it.

And, of course, you don't need to put your filter tube on the floor of the
aquarium. Half-way up is fine.
