Adding 2 part

[tjs1200]

Just started to 2 part dosing, I am sure I will have other questions, but this is the first, when increasing Alk and PH falls do you add anything to increase the PH?

I am working on getting the Cal and MA to target goals.

(salinity is 35 based on Hanna checker)

Thank you

So, for clarity, you are adding Kalk? I see that your DOS 4.2 is labeled Kalk. I don't see 4.1 defined. Also, the Alk is, IMHO far too high. I would stabilize your levels first and program the DOS to compensate for swings with 2 part, not Kalk. If you want to still use kalk, do so in your top off at a particular dilution based on levels observed over time. This is a balancing act that should be done SLOWLY over time to let things come to a stable level. Use this calculator to figure a balance of Alk and CA levels. Adjust over time to an appropriate level based on your particular tank's consumption and I think you will find the pH will fall in line.
Control the doser based on Trident levels.

You correct I am using Kalk , and am not using the 4.1 yet, I will take the kalk off the DOS and dose the Alk and Calcium. thank you for the reply.

Forgot the link to the calculator.

Also, a good read...

Looks like your got your system dialed in sir. Numbers looking pretty good.

Thanks! She's pretty stable and predictable. Ca reactor and 2 part for bumping things as needed.

Yeah, that’s how I roll myself. I haven’t jumped onboard the Kalk train on this system yet. I did on my last, but currently using the Calcium Reactor as my primary and 2-part to tweak from the GHL 2.1
