controller question

[Kurtl000]

I know nothing about controllers so bear with me but are there any that monitor alk and calcium?

[James983]

Pinpoint makes a calcium monitor, but it is expensive and from what I have read somewhat unreliable. I don't believe anyone makes a Alk monitor.

There are rumored to be upgrades coming to the seneye monitor that might do that. Need to use their slides for testing that need to be replaced once a month or so. Not sure what the cost ratio to traditional test kits are but it's something to keep an eye on

The Pinpoint calcium monitor cannot be kept in the water all the time, it's more for manually testing with the probe when you want a reading. The membrane on the probe would be destroyed if you kept it in saltwater over a period of time.

[Kurtl000]

Alright that sounds good easier than doing the manual tests all the time.

Alk is the only one you need to check often. Cal does not drop as fast.
Salifert is as easy as it gets for accurate testing.
