i have white gravel as my substrate its quite fine but the problem is that the gravel is getting a orangey colouring to it though and was wondering how to clean the gravel back to its pearly white colour? cheers
Short of taking it out and washing it completely i dont think you can, i had the same problem. Try quite a few bottom feeders/shrimp?
also whats the best way of cleaning it when its out the tank? cheersorange coloring on white gravel sounds like brown algae. is your tank only a few months old? this problem often times goes away on its own, once the chemistry stabilizes. corries wont help with that anyway.
