Hello Merry Christmas. I have tesco cat litter in my tank and it's a very good medium but very light .what can I cap it off with.In the past I have used sand but sand always goes anaerobic in areas .

If you can get hold of any gravel that's 2mm or so, that would be ideal to cap off. 2cm should be mor e than enough.
You can use it without capping. I think the cat litter will always tend to end up on top over time, because it is large, light grains.I am setting up a new tank for my Daughter and I was also going to use cat litter. Does cat litter always need topping off and if so is there anything better than gravel?
