thats what i got kdh 6 but, tested cal 3 times right out of bucket with readings of 560 to 580 way to high for me
i actually didnt know that it mixed that high, till i did a 30gallon water change, and got up the next day and all my xenias was dead, toadstools were al wrinckled up, and lots on numorus corals dead or about dead, all my water paremitors where fine except, khd and cal which were 6khd, and 520 on cal, so i checked some what that i had already mixed and i got a reading of 580 which was 29 drops, i though i had to have missed counted so i did it again and 580 and again, so i was advised to go get my water check and a friend of mine checked with his kit and got the same readings, i dont know if i got a bad bucker or not, but i have been doing some research on the subject and im finding a lot of different oppinion on it, imagine that lol. but most say its got a crazyly high cal, which i guess in turn doesnt help the kdh too much, i sold what i had left, and the guy that bought it bought it for the high cal, just too much for my tank
