Mitigate Swing in Alkalinity

[dadart2028]

Hello,

I have a Waterbox Frag 105.4, Dosing Kalkwasser 3.5ml/min (12hr 10 pm-10 am), and also using CALC RX 11ml/min (12hr 10 am-10 pm).

I want to mitigate the dip that usually happens around midnight testing thru apex. It seems like I lose about .3-.4 dkh in alkalinity.

Any suggestions on how i could get this fix.

This Chart shows the dip from 8.22 DKH to 7.89 DKH. time frame is at 1810-0019

Under .4 swing isn't horrible. What are you using for dosing pump?

Are you controlling reactor ph/co2 with apex?
Why not run the dosing 24/7? If your trying to flatten the valley. You can increase the amount dosed during the alk drop.

Yes I am using the APEX controller for PH and CO2

I am using Kamoer STP continious for the Kalkwasser and versa dosing for the calcium reactor

Should I be increasing the Kalkwasser or the Calcium Reactor?
