50-60% once a week on 2 30g and 2 50g tanks. 30% twice a week on 150g tank. i could do more but the water pressure where i live right now is VERY low, and it takes a long time to refill the 150. if the pressure was higher, i would do larger WC's.
water changes, how much, how often, how much is too much

I have 7 tanks, all but the qt tank is planted. I do 50% once a week. Every friday night is tank night. Hey, I'm married so what else do I have to do on fri night.
