Doser

[quickreefer]

Want to add a doser to my setup for calc and alk but not really quite sure how the work can anyone fill me in?

You can go with a standalone doser like the Kamoer https://www.marinedepot.com/Kamoer_...oer_Deepwater_Aquatics-PL10501-FIDPET-vi.html which has all of the programming on the unit, or something like the BRS Doser or Apex DOS which you control via controller programming. I currently use both, with the DOS controlling water changes, and the Kamoer dosing ATI Essentials. You can control how much (ML) of each you want to be dosed over a specified time frame. Anything more specific you want to know?

How does it know how much to add?

 

[sfmacguy]

Ah! Yes you have to determine how much you are using, by testing the water parameters for Cal and Alk, if that's what you are dosing, and then adjust the amounts to what you want. There is an awesome calculator here: http://reef.diesyst.com/chemcalc/chemcalc.html.

Is there any that test water for you then doses accordingly if not someone should make one

 

[sfmacguy]

There's CoralVue's KH Guardian Pro: https://www.coralvue.com/kh-guardian-pro which will do Alk, and the Neptune is releasing the Trident (unknown release date), that will test Calcium, Alk, and Mag, but then you would need a separate doser to act on the measurements. Those are the only two that I, personally, know about.

I mean iv never dosed for anything in my tank and have had pretty good success what are the benefits?

 

[sfmacguy]

Being able to maintain stable Alk and Calcium between water changes

 

[quickreefer]

What are the desired readings for that

 

[sfmacguy]

Calcium : 380-450 ppm
Alkalinity: 7-11 dKH
With the goal being to keep it stable, so it doesn't swing.

 

[quickreefer]

Can it be done by hand or no?

 

[sfmacguy]

I'm sure its possible, but I, personally, like dosing throughout a 24 hour period compared to all at once.

 

[quickreefer]

Okay gotcha thanks would the jaebo one suffice ?

 

[sfmacguy]

It should work fine, Just be sure you calibrate it, and keep an eye on it. I have never had a Jaebo product, but have seen both praise and concern for them.
