A reading of 230 is around 13 drops, not 230. Each drop is about 17.5 PPM. 230 dkh would be 230 drops. I bought new test kits and am still getting a KH reading of 230 ppm & a calciium reading of 540 ppm.
I did catch that. Sorry. I always use the degrees. It's eaiser that way. If you are going to take the time to multiply your degrees to get ppm. You should do it by the real factor of 17.9.
What is in your tank?
Do you have any corals to put a demand on your alk and calcium?
I believe, if your gravity is low, then increasing it is going to increase your readings. What are you using for water? RO/DI?
What are you using to measure your gravity with?
