Need some advise from those of you in the know about sand substrate please....
So I think ive pretty much made up my mind to change to sand, but im going to go for black or dark coloured as I dont want to see too much poop (as explained have large community tank plus large BN plec!).
Its pretty expensive so do you think I could get away with a 25kg bag for a tank of 250L ? Its a bow front tank measuring
4 foot long and width 1ft 3 inches. Also there seems to be different sorts and grades of sand , and obviously im avoiding any that say marine, so which is the best to go for and what are the benefits please?
