Kalkwasser

[fishmaster818]

I want to start using kalk so ive been trying ti figure out the best way for me and i think its through my top of. So can i just fill me top off with kalk water and it will dose whenever my top iff turns on

 

[heathd.hd]

That's my method. No issues

 

[fishmaster818]

Okay so just mix in top off container

 

[heathd.hd]

I have a container I mix it in. But yah u can do that also.

So right to left I have Rodi kalk and salt water. The kalk and salt containers have powerheads. I pump 20 gallons into the kalk container turn the powerhead on add kalk and some vinegar let mix for an hour than let sit over night. I than use as needed until I mix again.

You need to be sure your top off system adds the water slowly enough or in small enough amounts with each triggered addition.

Its an eshopps top off so it tops off slowly

Do you know how much enters with each triggering?

Adding 1.25% of the tank (or sump) volume in saturated limewater will instantly boost the pH by more than 0.6 pH units, and that's why small additions are needed.

I dont. I typically go through a little lest then a gallon of top off per day

How quick does your top off add kalk. Will a float valve work

 

[heathd.hd]

Yah mine just puts maybe a cup at a time in. Probably 1.5 gallons a day.

It keeps my ph around 8.1 night time 8.2 during the day. No worries there. My alk stays around 8.4 - 8.6 testing weekly. It's really simple for me. I did alot of research reading everything randy has ever wrote about it. I also asked alot of questions

 

[fishmaster818]

Okay because i really want to do this. To keep everything stable

 

[heathd.hd]

That was kinda my goal also with end result sps dominant tank. In doing research this method seems like it would have the least amount of alk swings.

Okay thank you.

After watching my top off it goes pretty slow

What is the concern here?

I ask because I am using Kalk in my ATO and am seeing "PH Spikes" in my sump...but they seem to dissipate fairly quickly.

My system volume is ~65gal (44DT, 3plumbing run to the basement, 18sump) and I think the ATO is putting 1/4 to 1/3 gal of Kalk in at a time. I go through a gal to 1-1/2g a day.

Thanks!

[Randy Holmes-Farley]

Those size pH spikes are not a concern.

 

[ultimatemj]

Great...but what about this afternoon's spike? LOL

Still 8.47 three hours after

 

[heathd.hd]

Ouch u sure that's accurate?
