Which KH/Alk controller are you using? How does it work?

[scuzy]

After using the kh director for over a week the reading has been pretty spot on. Although initial setup calibration was needed but once done it's been nice and easy. I test 2x a day to see if i need to fine tune my calcium reactor. So far so good. Hamna raeder 8.8 director 8.9 and nyos kit shows 9 drops.

So you are using kH director for testing and reading. Can it control and tune your ca reactoer automatically?

It can but requires a profilux controller. To shut the co2 regulator.

Even if it could, as previously discussed, it's probably not a good idea to automate it.

Shut off co2 regulator is not fast enough to respond. Can it turn off the pump to stop drop from ca reactor?

I think the big problem would be the opposite. What if it gets a bad reading and then leaves the pump on? You'd need some sort of redundancy.

For example, when we hook our heaters up a controller, we typically use the controller to turn the heater on or off, set a few degrees lower than the heater itself. Let's say you want the temp to be 78 degrees, so you set the controller at 78 and the heater itself at 80. If there's a bad reading, the heater will shut off via its own thermometer when it hits 80 degrees, so the tank will never get too warm. You'd need this same type of redundancy for the CA reactor.

Think the adjustments as re set once and waits until next test. I don't know how it actually works as I'm using it as a way to see my calcium reactor needs adjusting. I would assume there are fail saves as there might be a ph swing or there is a set time the dose can be on? Who knows not running my setup like that. I set it to test to compare readings daily. Adjustments are all done manually.

Agree. But we usually fine tune ca reactor once a while manually after each test. If KH director can turn on/off the feed pump for drop the water from reactor, it will help adjust KH. If there is reading error, it should not impact too much since the drop from reactor is limited which is not the same as two-part dosing. The two-part dosing may cause over dosing if KH is read wrong. Does it make sense?

I have the kh gaurdian. Been on for month + now. Keeps alk at 8.9-9.1. Corals couldn't be happier.

Which guardian do you use? Can you do me a huge favor and send me a link? I'm tired of KH dosing and would like to automate it.

Probably the kh guardian and not these kh guardian monitor only version. You can do that with the ghl kh director for dosing as well.
