Yeah, it was just an idea. I do have an IV setup from when my cat was sick (long sad story). So, that is probably the best bet.. But, I was thinking this would be cooler because you wouldn't need the
kalk mixture hung above the tank and looking all tacky. The valve would meter the
kalk. If you had it BARELY open, it wouldn't overdose.. Maybe just fill a clear tube and watch it barely move. That would be effective. As long as nobody moved the valve.. all would be good.
I would always err on the side of too little rather than too much anyways.
