Parameters off

So I was dosing my ALK for the last week or so due to finding out that my KH was low all this time, I was reading it wrong (not sure how but I was) so I have been dosing with baking soda...but the last few days I have read my KH being so high, to the point where it doesn't turn yellow (using API KH test kit)...will having REALLY high KH destroy my tank? or will it be ok? The only reason why I am asking is all of a sudden my Birds of Paradise is competely bleached out >< was it the high KH fault or some other parameters...



Here is what I test:



SG 1.024

PH 8.5

CA 400

KH 12+ dKH

NO2 0

NO3 0

Phospate No Algae :o
