What do you recommend for a reef tank? Something more accurate.

I’m mostly a FOWLR guy, but I love the convenience of this IceCap product. If you could calibrate it against a “known” salinity sample, that might help with a reef tank— but presumably this tester is at least “consistent,” if not in fact “accurate.” Best wishes.

Thanks.

Just make sure you calibrate before each use.
