Using an API test kit (drops not strips) I decided to test the ratio of 1/.5 of Salty Shrimp GH/KH+ and I am not getting a ratio of 1/.5. I start with RO water of 5PPM and add Salty Shrimp GH/KH+ until my ro meter reads 200ppm. If I am not mistaken the final PPM reading should not affect the ratio and just increase the degrees of hardness.
At 200PM I read 3 degrees of KH and 9 degrees of GH. Shouldn't I be getting 3 degrees KH and 6 Degrees GH? How on earth is this possible unless my API test kit is off or the salty shrimp is not the correct ratio? Am I misunderstanding something? Its obvious the number of drops it takes for the test kit to change color. The color keeps getting darker in intensity before obviously changing to a different color.
