lime water

[HammerHead]

Does everyone use lime water for there top off water?

 

[capescuba]

I do ... I have a Kalk Mixer that my RO goes into, then an auto-top off from there

 

[Thales]

I do.

 

[Elite]

I do too... Not as regulary as I should "too busy with other thing" ....

I have a 5 gallon tankw ith premixed limewater that is on an autotopoff.

My pH is high enough WITHOUT limewater, so I don't. I realize I can add vinegar to make it a lower pH similar to liquid calcium, but it really has become a chore.

 

[capescuba]

Fish and Chips with Vinegar! - There really is nothing like it!

 

[bareefers]

Yes, I use it to raise my pH from my calcium reactor.

I had to remove my Ca reactor now im having a PH problem at night. I going to try and use lime water in my makeup water to help with this.

I run a GEO Nielson Reactor for my topoff with great results

 

[capescuba]

But it's not really a "reactor" right? It just mixes water and kalk, unless I am missing something?

[capescuba]

Exactly - it's a mixer

 

[HammerHead]

What's the PH of the water you mix. Has anyone checked theres?

 

[sfsuphysics]

depends upon how much you mix.. but typically "saturated" lime water is something like 12.4 pH

 

[HammerHead]

So the water for top off is 12? wow that high What keeps the tanks ph from going high. I mixed up some but I was checking my PH as I added right now my top off water is 9.

Todd - how do you like the Geo?

 

[bareefers]

I love it - the price is a bit much for a new one, but if you ever see a used model for sale I highly recommend it. I don't think I'd ever go without one from now on...




The pH in the chamber is 12+

 

[HammerHead]

I need more info on how to use this stuff. I need to know if you guys adjust the ph to what you want or use it full strength. What happens to the PH when the lights are on.

 

[badpacket]

pH goes up when lights are on due to photosynthesis and O2 release. With lights out, no photosynthesis and no more O2 is really produced so pH goes down. Least thats how I remember it.
