Kalk reactor operation question.

[Reef Junky150]

Has anyone ever tried to run pump out of sump, tank water through reactor instead of fresh ro/di water. Reason I'm asking is I would like to run on a set program and eliminate through topping off only. Would it work?
And go...

You cannot use seawater in a calcium hydroxide reactor.

You will precipitate magnesium hydroxide and calcium carbonate inside the reactor, and will deplete the tank water of magnesium and possibly alkalinity.

Why not run a pump from your top off container to your Kalk reactor that is controlled by a timer, etc? It would be independent of your ATO pump, but it would collect from the same reservoir.

I could.

I could.

This is how I set mine up. I hope it's ok to link to my post on another forum...

How has that setup worked for you? It seems pretty straight forward

It's been working well. It's only been setup for 2 weeks now. However, I have found my levels are staying consistent compared to before where I would see a drop within a couple days.

I keep looking at it, but that's just to make sure the timers are working and that everything is still working as it should. So far, so good.
