Sorry I haven't been around that offen but I have been Realy busy latly but I finaly got some time now to get on the computer and I have a qurstion I was talking with a friend and he said that I should raise and lower the water level in the tank according to the session to mimic the natural environmental prosses of water but that seems like a lot of work and I also doent want to flood the tank or lower the water to mutch so I was wondering if thats Realy necessary or not?
