Here's a pic of my drip system. The two gate valves are the supply, the unused valve is for my next tank going in maybe next week. I trickle in about 1 gallon an hour to my 450. The extra water overflows into my sump then overflows again into my yard (roses love the fish water). No water treatment, no buckets, no mess, no time waisted.
It surprises me how loyal the "water treaters" are to their product. They will defend their product with terms like chorine and clorimane (spell) and the health of your fish, bla, bla bla. It's like talking to the locals here in Phoenix about the heat........"its a DRY heat" so your telling me 118 is not that hot cuz it's "dry" ???
I never treat the water going in my tank, the fish get the same water my family and cats get. My fish breed and grow so it appears they are happy, that's all the data I need.
