Mixing kalkwasser with tank water not RO, possible?

[Duzzy73]

Hi,

can I use water from a manifold (tank water) to mix and dose kalkwasser and it’s stirer? I don’t like the thought of dosing via RO top off because it means the kalkwasser doses at different rates based on external temp and humidity.

have I got something incorrect here? Happy to be corrected (don’t tell my wife )

regards Duzzy

I use a dosing pump to draw water from the tank and drip it back after the stirrer. Makes it a stand alone part that doesn't work off an ATO.

I think that would have a lot to do with the amount going through the stirrer. I run on a consistant drip every 5 seconds. I don't run from a controller that may put a lot through it. The stirrer also runs every 4 hours for one minute to keep the kalk mixed.

I wanted the stabilty of a drip. The pump can be expensive, but I didn't want it to dump a cup or more whenever the ATO refilled the tank.

I use a dosing pump controlled by my Hydros controller to push RODI water into my stirrer and it overflows out to the sump.
My ATO is separate.

That’s a great idea so effectively creating a secondary ato. You’re obviously setting it under your daily evaporation is that correct?

 

[Duzzy73]

Yes
The amount dosed never comes close to what my ATO adds. I have a lot of surface area for evaporation.

That the way I’ll do it I think. Do you continually top up the kalk with RO?

I run mine the same. Kalk dosed separate from ATO via dosing pump. Both are fed by RO/DI from a 30g reservoir. I have my dosing pump set to turn on at night to help balance pH. Drip rate is pretty low, so my ATO still kicks on regularly. Once my system demands more, I'll hook up my Calcium Reactor again.

Thank you. I’m guessing you always add less kalk solution than the evaporation amount then just top up the difference with straight RO as well. I also thought of using a large diameter tube to prevent blockages and then feeding it into a filter sock to not crud up my vectors.

Do you also dose calcium through a reactor and will that and the kalk balance/level out the ph?

The biggest pain was getting the drip tube to not clog.

Attach silicone tubing at the end where it drips and slit it back about 1/4" perpendicular to the tubing. Looking at it from the end, especially cut an "X" like a pie, but only 1/4" or so. The calcium carbonate buildup won't block the flow, and most of it just falls off as it doesn't adhere to silicone well. I pinch the end with my fingers every month or so, but just becuase. It's never actually clogged.
