It has little or no nutrients & plants find it hard to root in it.
If you're wanting a planted tank, ask on the planted section for advice on substrates
i have used this sand in two of my tanks and am shocked at the ph level in them. Ok its my own fault for not checking every day but in a few weeks its dropped right down to 5 from 7. I've put in coral sand to see if that will help and doing 25% water changes every other day to raise is slowly. My tap water is 7.5. My water in Edinburgh is very soft. Thanks for reading. Btw my fish look ok.+1 for play sand iv used it in all 3 of my tanks now. just make sure you wash it
