Sand and water filtration

[paul]

hey all i was talking to my aquariast an he said sand shouldnt be used in a tank because it impairs water flow through the substrate which results in poor bacteria growth, i told him axies swallow smaller gravel and small bits of food get in bigger gravel so wat are ur thoughts on this

i use sand much easier to keep clean. its true what he said about poor water flow so every now and again i give it a turn over. while this does make the tank dirty for a while it keeps it much healthier

I'm with Sharn on this one. If you don't put a huge thick layer down, and you stir it up on occasion, you don't have a problem with anaerobic conditions.
