I want to use the bathtub for filling my tank it would be much quicker and water is softened both cold and hot vs the kitchen sink slow and softened on hot side only.
But the tub is akward you just cant screw A hose on it how do I do it
I wouldn't do it at all. Soap residue can kill fish and amphibiansSubmersible pump and a length of hose. How far is the tank from the bathroom, and is the tub used for bathing? I would be concerned about residue from soaps and cleaners.
You could just place a plastic tote under the faucet and pump the water from the tote. Other than removing the spout and threading a diy coupler to it. I would think that would be the best option.
Any ideas for the hose I don't want to use A garden hose I am worried about what chemicals they use on the inside of it.
The clear stuff that is used on A python when you go yo about A inch hose gets pretty expensive when you go to 30+ feet
There has to be something safe and big enough that isn't too badly priced
