Hello all, I recently joined this forum, it's very informative, I recently got a 10 gallon tank for fresh water fish, I am trying to build a UNDERWATER SAND FALL, how do I get more SAND TO BE SUCTIONED also what is the best recommended system, my daughter is getting very impatient as we have not placed any fish in the tank as yet. Tks for any advise and pictures:sunglasses:. Mark ( GWSHARK8@gmail.com)
I've never seen an underwater sandfall.
My guesses for lifting sand would be an airlift tube system that is buried in the sand and with a cap on top which forces the sand out in one direction while letting the bubbles continue upward, preferably out of sight.
Otherwise your best best is an archimedes screw pump. You won't find any that are aquarium sized, so you'd have to make one.
