I see a lot of complaints about water changes, specifically the work involved. I have a 300g display, so when I change water it's about 50 gallons a week. That is a lot of 5gal buckets...right? Nope, I spin 2 red handled ball valves and watch it happen. The valve on the wall is the New Water inlet, The valve in foreground is my tank drain. White container is my RO/DI ATO reservoir. I hope this will give some of you some inspiration to make your hobby experience easier.
