I have just filled my acrylic 55 and I used sand as the substrate. I rinsed all the sand off pretty good, but there was obviously some cloudiness left in the tank. To help clear this up I started running some filter floss with some activated carbon. Unfortunately, I accidentally got a bunch of carbon in the tank.:wall: I got most of it out, and I did another drain and fill and my water is clearing slowly, but what I want know is if the carbon that's sitting on the bottom is ok to just stay there. It won't vac up very well and it's not to much, but it's enough to be noticeable. Anyway, if I just leave it there will it be ok?:help: Thanks in advance for the help.
