That's cool Eric.

Does the RKL's ATO come with a certain kind of sensor? Does it measure salinity or water level?

Float switches

Do any of them base the ATO on salinity, which is the real measurement we should be basing top-off with?

 

[wes]

Not that I know of. Salinity monitors are prone to drifting out of calibration. This could be catastrophic because the slightest difference in salinity could mean several gallons of water getting pumped in.

The float switch or level sensor, while not perfect, is simpler, cheaper, and in my opinion more accurate than relying on a calibration to determine the amount of water being pumped in.

You can purchase a separate PM2 module and conductivity probe for the Reefkeeper (Apex has a similar module) and write a program for the ATO to be controlled by a set salinity but honestly, I haven't dug that deep into the programming. I'm testing my Apex Lite out now using the pre-loaded programs with just a couple minor tweeks to suit my set-up.

I'm not really up on the Reefkeepers programming but it should be pretty similar on both companies controllers.

It looks like everywhere I look the RKL and most of it's modules are out of stock. I will keep looking tonight. If I can order the RKL and whatever else I need for around $200 that would be about the same the other ATO and Ranco I was looking at getting costs.

I don't mind spending more than that but I'm not trying to get some program as complexed as yours Eric to monitor my tank. I'm just not that into it.

These guys seem to have it.

It sounds a lot more complicated than it really is. Most of the programming is preloaded and over half the changes are simple multiple choice selections from drop down menus.

Thanks Redfish. I am going to read about it a little more tonight to make sure I can get the ATO and extra strip to go with it. If I can I will surely be ordering one!

I really appreciate the help. If I can get that and add the ATO I am set!
