Currently using argonite sand, have been using it for the past few years in my set ups for my tanks..expensive yes..but an added value to the calcium...but you would still need to top up your calcium where & when necessary....
Helping a friend to sell his two 4ft tanks with rod iron stand. Self collection at Simei. Tanks are brand new...
48" x 16" x 16' - 6mm glass thickness..
Wanting to let go at $150 (Neg)
Cheers
