Advice: Unhappy tank..

[ghztew]

I checked my KH last night and it's roughly in the 120 range.

Will apologize I have very little background in chem etc.. so my numbers are usually based straight off the readings I get from my tests.

The package gave me two interpretations for the 120, in one area it said anything between 105-125 is good for salt tanks, and then in another area it said if it's over 90 than it's to high.
