Top-off water alkalinity

[smoorman1]

Do any of you correct the alkalinity to the RODI water before adding fresh top off water.

I do not and never have. Well, unless you count occasionally dripping kalkwasser.

 

[Reefing102]

I do not. I know plenty of people add kalk but more for dosing purposes than balancing Alk in RODI specific purposes

 

[smoorman1]

Will the top off water slowly reduce alkalinity?

Will the top off water slowly reduce alkalinity?

It shouldn’t but life will reduce it. Thats why we dose alk, kalk or CA Reactor.

For clarification, topoff won’t as long as you’re doing regular water changesz
