Water change dilemma. Suggestions?
Unique situation. My tanks are in a finished basement and there is no hot water faucet. There is a hose near back door that I've been using to fill tanks.
During spring/early fall, ground water is 75*. During winter, much colder.
I've been doing the bucket brigade. Fill up 10 gal trash can, dump behind house. During summer, fill up is easy, I just mix the water in trash can with prime, AB and equilibrium, then use 1g jug to transfer to tank.
On fill up, I carry 5g of hot water from upstairs, and mix 25% hot to cold from hose.
This is very labor intensive so I built a python.
The dilemma is about adding hot water directly to tank. While the tank is slowly filling with cold water from python hose, I thought I could just add a few pitchers of hot water to offset this. But then I realized localized hot water could kill plants or fish. idk how long temp transfer would take.
Any suggestions to help in automating the drain fill process?
