Ok background first have a 20 gallon mixed reef. Currently using 2 part solution that I test ca and alk every 2 days. With alk and ca dosed in equal amounts.
Was reading up on some either released or upcoming continual alkalinity tests. I also saw the price on these lol.
So my question is using something like an apogee Ca+ ion probe in a stable system accomplish a similar goal at less cost and significantly less labor no refilling regent and ro water.
My theory is if your tank is stable and using a ratio of one to the other. That as the rate of consumption is increased in Ca+ that alk consumption will increase at the previously measured ratio.
And if this holds true could one use this method to reduce regular alkalinity testing to semi regular testing say 1 week or 1 month apart to readjust for any fluctuations in the ratio of usage?
Asking before I start setting aside for a probe and chip as still a hefty investment. But would give peace of mind while away from my tank for extended period of times.
