Careful here... The CONCENTRATION of Kalk will self limit because it can't dissolve any more...but that doesn't mean that you can't add too much Kalk to your system.

The amount of Kalk your system needs is based on how much Ca/Alk your system needs..NOT how much evaporation you happen to have.

It is certainly possible to add too much Kalk to a system by assuming that you need the same amount as your evaporative water. Checking your Alk level will tell you if you are overdosing.

Once you have significant Ca/Alk usage, you'll probably need more Ca/Alk than Kalk alone can provide. At that point, you might as well allow Kalk to flow with the evaporative replacement...but at that point you would also be supplying Ca/Alk some other way as well.

Ohh soo confusing!!!

Have you considered 2-part dosing? If you already have a PLC it can't be that hard to set up a couple dosing pumps.

Another issue you might have is kalk back syphoning into your ATO water holding reservoir. I bring this up because its a problem that I have been having and if your fresh water tanks are using the same reservior they could end up being supplemented with kalk too... I've tried adding a small check valve. It jammed open within a few weeks so I dont know what you can do to prevent this.

I've used the new tunze check valve, it's worked well.

Thanks I'll have to take a look and see if I can find one of those. I used a Mur-Lok check valve. It added a lot of resistance and then became plugged pretty quickly. I tried cleaning it a few times but it just kept sticking open.

No, I havn't explored that avenue yet. Most dosing pump's I have seen are expensive. I'm a cheap, DIY kinda guy LOL

Is there a good read somewhere? Cause I got till Tomorrow Noon to figure out what which way I'm gona go LOL. headin to Van and the stores Wed.

again no experience on this but from reading, seems a good DIY doser for two part can be a couple of Drew's Dosers or even a Aqualifter pump and individual timers or since you have a PLC, control the AC receptacles as required.

The Drew's come in a few different ml/minute sizes.

Check this thread, some pictures and gives an idea how much to dose

[banditpowdercoat]

I actually like the Aqualifter idea. Hmmmmm

[banditpowdercoat]

So basically you make up a concentrated batch of Ca and a batch of baking soda, Use the Aqualifter to dose these? Thats cool. I allready use ChemMaster's Ca and Mg in my New SW and manual dose. Why didn;t I think of automating it I dunno?? LOL
