Is it just me or is this mean. This really bothers me. I feed every other day and I feel bad on the day I skip, but feeding once a week? I don't think this is a good idea. I don't think people should sacrafice the fishes health to keep nitrates down. My question is how would you like to eat just once a week? Sorry I just had to vent about this. If you do this please RETHINK it.
