Kalkwasser question

It's on a tunze osmolator ato. I can't slow the evaporation down. Maybe lower the amount of kalkwasser per gallon?

Yes, if it is delivered from a settled reservoir, that’s they way to do it. It’s more complicated if you are using a stirred reactor.

I will be setting up my new doser. The evaporation rate was just too random. What would be a good start to dose every hour for 24 hours?

That would be full saturation .

What is your estimated daily alk demand and your system's total water volume?

Test, do some math, adjust accordingly. Or just use ato by far the most reliable method to use kalk

My evaporation has been so random the it causing to many swings. That's why I'm going to a dosing pump. Was looking for a lower end starting point and adjust from there.

You can use haft the dose on ato instead of full dose

I have tried all that. My evaporation is crazy. I will go through 5 gallons in 8 days and it won't meet my needs so I will make it stronger and then it only takes 4 days to evaporate which spikes. I can't figure out why. Nothing changing.

You may try switching to regular IO salt and as others have pointed out a dedicated dosing pump for your Kalkawaser is a more reliable method of adding it to your system.. I have a BRS pump set up on a simple mechanical timer for mine, been running for about a year with no problems. It runs off and on from 10 pm to 10 am and helps keep ph from dropping overnight.

Dosing pump is different than mixing in w rodi for ato to dose. In ato, u can give general advise... 1tspn/gal for medium demand maybe.

Using a dosing pump will be max saturation kalk. Without knowing your system volume and rough daily demand (how much does alk drop if u don't dose for a day), it's impossible to give u any kind of guess.

I dose 2300 ml a day on a 65g tank. If you have a 35g cube and do that, you will fry it in two days. If u have a 180, it wouldn't be near enough.
