I noticed yesterday a sudden upward trend in my alk which prompted me to turn off my doser for about half of the day to keep alk in normal range. My alk is normally very stable, but in the past (before adding a trident) I'd test weekly and always get crazy consistant alk results, like 9.8 +/-0.2 for a dozen readings in a row. Then out of nowhere I'd get a reading of 11.5 and spend the next week or two doing daily tests and slowly dropping it back to normal with reduced dosing.
Now that I've had a trident for a little while, I'm seeing similar results. My alk is very consistant (at least at the same time of day) day in and day out, but every few weeks or so it seems that my alk will just start rising continuously for a day or so for no apparent reason. Is this something other people see as well? Is it likely a biological function where some tank parameter just causes coral to stop calcifying for a period, or is it more likely an equipment issue where a doser will suddenly dose more than it should?
With the trident, I can now catch these spikes early and prevent the alk from spiking so high, but am still curious as to what could be causing them in the first place.
