so: i made up a sample solution 1/4 cup Instant Ocean salts to 1/2 gallon RODI.(RODI TDS 10 ppm) tested it:
my solution --------------------- IO specs
refract. 1.025 ------------------- 1.022
API KH 8 dKH ----------------- 11dKH
Salifert Mg 975 ----------------- 1350
Hanna Ca 301 ----------------- 400
API Hi range pH 7.9----------- ?
i have added Magnesion to the tank
tested also
today --------------------------------------- 4/11/20 before Magnesion add
refract. 1.025 --------------------------- 1.025
API KH 6 + dKH-------------------------- 6
Salifert Mg 1155 ------------------------ 975
Hanna Ca 381 ------------------------- 321
API Hi range pH 8 -------------------- 8.1
my thoughts are thus: i don't trust the API test, both the reagents and my color sense. If I look at the fresh results vs the specs, I find a pretty consistent 72-75% of their specs. Except for the alkalinity the tank on 4/11 is similar to the fresh SW results. I think that I may ease the Alk up two points slowly. Starting when the ESV has dissolved.
