MikeYQM said:What's your pH normally? An Alk level of 13 could be depressing your Ca. Are you adding any buffers or other additives?
Adding calcium will lower alk, providing mag is at a reasonable level. Ph can be raised by increasing surface agitation (pointing a power head upwards so it breaks the water surface).

(Gas heat, electric stove?) anyways, I dose extra when the heats on to keep it up, otherwise I get funny readings on my kits. I thought it was just an expired kit, but that wasn't the case.

I hope you have a carbon monoxide alarm. Seriously.
