Just had a move around of rocks/plants and uncovered a whole patch of grey-ey/blacky sand where the rocks and lead weights have been (on a wood decoration, not the plants).
The fish don't seem to have been too bothered by it until now, and those rocks have been in for AGES, do you think it's safe or should I remove the whole patch of sand? I dont really want to take it out but I'd rather not lose any fish. I've done a 75% waterchange to be sure but im not risking anything.
Thanks
Hannah
