I recently put in sand in my 10 gallon aquarium instead of gravel. So far everything looks great. I have not put any fish in the tank yet because i wanted to see how the sand would work out. I have a basic AquaClear filter with the mechanical, biological, and chemical filter inserts. Will the sand affect the efficiency and overall condition of the power filter?? And if not what would be some good "cleaner" organisms i could add??
