Ph to high

[Toshas79]

i told my brother to top off and to add some ph buffer to RO water but accidently insted of ph buffer he used kalkwasser mix.

Corals are doing fine, just ph my test kit doesn't have color to mach

Nice; just do a few big water changes, and that should bring it back down to a normal level before it has a chance to cause any damage.

that should help.

i from time to time put in a slurry of kalk and my ph goes up to about 8.6 is all

I'll try water change, somebody told me to use viniger, just have no idea how to do that

Thanks
