That is odd. What kind of heat do you have there? If it's natural gas or oil, you might have someone come out and check the heater over, but from what you're saying it probably hasn't been on much. Hmm...

AFAIK It's not affecting the amount of CO2 really, just increasing the concentration of hydroxide or hydrogen ions temporarily. PH is a direct measure of the amount of hydrogen ions in a solution. kalkwasser is calcium hydroxideAgnate80700 said:adding the kalk in large volume soaked up seriously over-abundant levels of co2?
It's more of an issue w/ time. With more coral colonies and/or increased coral mass due to growth, the PH change would likley become more noticeable between day and night. Just about all reefs have them to some degree, even ones using a reverse lit fuge.window being closed making the pH drop and not the night-day fluctuation. (I didnt used to have a fluctuation, but who knows now, maybe I do)
Your welcome They helped me a lot.Melosu58 said:Thanks for the two good articles Mike
