This. I'm trying to grow some real big polys (and fancy goldfish). I'm doing large water changes every other to every third day on both tanks and getting great results. I use a python now but during the winter and spring months it was too cold to pump in water from the hose and our bathroom/kitchen faucets wouldn't work with the adapter. So I refilled 50- 75 gallon with buckets every other day. I have NO patience for people who whine about water changes.People freak over 30-40 ppms nitrate for a reason, it inhibits growth and promotes illness in any concentration.
