Test kits can go bad, so I would buy a couple of new kits to double-check the results you're getting. If the current kits are accurate, most new kits will last for years if stored in a cupboard, so there's no waste. I'd recommend Salifert, SeaTest-Fastest, or SeaChem test kits, based on my experience. Hach and LaMotte are also generally good.
GH doesn't mean much in the saltwater world, as I understand the measurement. Only dKH is useful.

dKH and KH and alkalinity are pretty much identical except for the scale, for hobbyist usage. This article discusses alkalinity:

The Hagen test says what about the KH?
And according to the kit that means higher than what value?
OK, that may be high, but many many folks keep alkalinity in that range. I recommend 125-200 ppm calcium carbonate equivalents, but even mine is often a bit higher and that is OK. I'd continue adding drops up to at least the equivalent of 300 ppm and find out the actual value.
