My tank has been up and running for about 18 months now and I want to remove some sand. I find the sandbed too thick, I still want to keep a layer for my wrasses but it’s about 2” thick and it looks really gross where the sandbed meets the glass. There is all kinds of gunk built up in there.
I know I have to do it slowly but how slowly? And what should I use to take it out. I don’t want to risk any kind of cycle or algae to take off on new spots
