Still tweaking a new plant tank, 1 month old 90 gallon. Initial
startup plants are in, co2 running, chemistry good. I have some final
re-arranging of rocks and wood to do, plus I need to add to my fluorite
substrate. Any ideas on how best to get more fluorite to the bottom
without turning the tank into a particle soup?

I was thinking of using a margarine container, gently top up with
water, then put the lid on. Bring it to the bottom and slowly pour out
the fluorite. Make little piles in this way all over, then spread it
out later.

Another suggestion from the LFS was to use a PVC tube, a couple inches
in diameter, and pour the fluorite down the tube. Might work.

Ideas anyone?

Two gravel vacuuming tubes and two people. One to pour fluorite down a
tube, and the other to vacuum the fines which get released into the
water. I've never tried this method, but it sounds like it has
possibilities.
