Hi Max, works great for me. You can also get them in slightly darker/whiter color. Just to be on the safe side, make the little acid test to check if there is no calcium in there, which in return will raise your GH/KH-You don't want that ! Acid Test: Put a bit MURATIC ACID (Pool Supply) in a cup together with some sand. If you see a LOT of bubbling, the sand has tooooo much calcium and will raise your KH/GH to much.
