Are these parameters adequate for a FOWLR tank?

I preformed a test in a volume of approximately 5 gallons with a salinity of 1.026 specific gravity which was measured by a Milwaukee Salinity Refractometer.

After following the instructions the following readings were done:

All tests were applied with a 1.00 ml syringe

Test 1: exactly 0.29 ml were used leaving 0.71 ml of reagent which is ~430

Test 2: 0.27 ml of reagent were used leaving 0.73 ml of reagent left which is ~440

Test 3: 0.30 ml of reagent were used leaving ~0.705 which is ~450

All 3 tests give an average of 440 ppm Mg in a 5 gallon bucket.

Standard deviation is 10?

Test some fresh salt mix . Just to check mag

Test was done

You are supposed to read what is left right? Not the amount you used? Like I used only 0.3 mL of the reagent, therefore 0.7 mL is left which would make for 450 Mg ppm.

Yes, you are thinking about it correctly. The more reagent it takes, the higher the value. If you use all the reagent, Mg would be 1500+ for example.

Guess the Mg is around 440 I suppose.
