You can buy a shower diverter that installs between the shower pipe and shower head and just use that when you want to do a water change with a hose. You can run the tub faucet until the correct temp and then switch to the diverter for filling the tank.I have had problems with the shower head leaking so I don't want to take it on and off every week
That looks like something I could use in my garage. I am going to install a laundry sink out there this week and would like to fill more than 1 of the 10 tanks out there at a time. It is going to be so nice not to have to wait for kitchen sink time to do my water changes.
Hey robham thanks for sending this info to me I bought one of these was I connected A 1"id hose to it adjusted it and it worked perfectly I can now add water at A rate of 300GPH +I can see an issue with directly connecting a hose to the spout or showerhead. It would be very difficult to get the desired temp. The water has to go somewhere while you adjust the knobs to the correct temp. You would need a shut off valve for the hose so you could get the temp right, then cut the water flow off while you insert the hose into the tank. If you go that route, it makes sense to get a 50' python since it is already set up and aquarium safe. If you get a pump, look for one with an adjustable flow rate that will work with the 5' head height. This is just an example, but the aapw series pumps available on amazon are reasonable and would work.

300 gph is more than the utility sink faucet I got is rated for. That must make for some quick water changes, glad it worked out the way you wanted it to. Do you just coil the hose and stuff it in the bucket when not in use?Hey robham thanks for sending this info to me I bought one of these was I connected A 1"id hose to it adjusted it and it worked perfectly I can now add water at A rate of 300GPH +
