Setting up a 29 gallon tank with native fish (mostly sailfin mollies) I have heard that lime rocks in an aquarium make the water hard and effect the PH, but I have also heard that mollies like hard water. If anyone can please @Harry Pristis *hope I did it right, think I did. Harry, I know you have mentioned you have a tank. Do you think the typical peace river gravel and some fossils for substrate will be good with native fish? Thanks for any input.
