hi folf i have a question, actually 2 questions i tested my Ca levels and found out they were very low 120 to be exact , i know normal is 400 450 roughly , so i went and bought kent marine tech cb part A and PART B ive been using it for 3 days now acording to the directions and my Ca has only gone up to 160 , my fist question is how long does it take to bring the levels up ? , and does this product also raise my kh , because i started with a kh of 12 which i know is high but now its at 20 ,,, any advise???
