Yet Another Nutrient Calculator dGH incorrect?
Hello all. I could be misunderstanding this but here goes.
Your addition of 1.5 tsp/caps MgSO4.7H2O to your 75.0 gal aquarium adds Element ppm/degree Mg 2.66 S 3.51 dGH 0.61
I'm not sure how 2.66ppm of Mg relates to 0.61 dGH? My understanding is that 1 dgh = 17.8ppm.
2.66ppm of Mg should raise hardness only .15 degree. Even if the sulfur content is added the result would be very wrong too.
Any idea what's going on there?
