SRC Member christan1959 Posted July 12, 2017 SRC Member Share Posted July 12, 2017 Hi all, Just upgraded to a 6-footer. Running a calcium reactor. Tested the water after one week, and was shocked to find Ca level of 261 (Hanna kit). Couldn't believe it so did an immediate retest. Got 316. kH was 9. I've never seen such low Ca in any of my set ups. Any idea what is causing this? I've dosed with liquid calcium, and will do a retest same time tomorrow. Hopefully this is just a temporary glitch.

SRC Supporter Harlequinmania Posted August 18, 2017 SRC Supporter Share Posted August 18, 2017 Most likely is due to the tuning of your cr.

SRC Member christan1959 Posted August 18, 2017 Author SRC Member Share Posted August 18, 2017 Mystery deepens!! I raised calcium with powder. Thought that was that. But lo and behold, it kept rising. Now at 600!! Cedric, cannot be reactor tuning. Because kH was ok. Possibikities: 1) FM salt batch has low Ca. 2) Hanna regent gone bad (spike happened when I opened new powder regent). 3) Both of above. Anyone has other theories? This is perplexing because before this episode, my kH and Ca always moved in tandem - never separately. Quote Link to comment Share on other sites More sharing options...
