Hi guys. I'm using the Instant Ocean Reefmaster Alkalinity Test to determine measurement of carbonates in my tank. A little bit confused about it... The ROUTINE TEST instruction says that if the first drop of the alkalinity reagent turns the sample water yellow, proceed to PRECISION TEST (which has the same procedure with the ROUTINE TEST except for dividing the number of drops to 4 instead of 2).
On my sample, the first drop of the reagent turned the sample blue so I'm doing the ROUTINE TEST. Then it turned yellow-green after 12 drops. As doing the ROUTINE TEST, the result would be 6 meq/L which is very high. The instruction says that it could only test up within the range of 0-5.0 meq/L.
Is the result accurate? or should it be 3 meq/L (PRECISION) instead of 6 meq/L (ROUTINE)? Hope you could shed light. Thanks.
