Could I add 1 gal of Kalkwasser to 4 gal of R/O topoff water?

This way I could dose Kalkwasser without a drip. Would this work or is it too dangerous?

i wouldn't recommend that, even if the resulting 5g is for an auto top-off. i'm not sure where the pH would end up but you can test it after you mix the two. if it isn't super high (i.e. pH 8.8<) then i guess it wouldn't result in an instantaneous meltdown. X)

 

if you're using that to do wc's then i definitely wouldn't recommend doing that. kalk isn't something you want to mess around with on big tanks let alone little ones.

I use slightly less than 1/8 tsp. kent kalwasser powder in 1 gal of RO/DI water. I then use that to topoff. I don't have an auto topoff. I topoff either once or twice a day manually and add the water into the HOB so it gets mixed a little before entering tank.

 

I would think that the dilution would be great enough to use the 1 in 5 ratio you mentioned. WOuldn't do it for water changes but topoff would probably work out fine.

i add a teaspoon of kalk per 2 gallons of water for my 20gallon high . Works better for me.

dont dose if you dont test for it
