Geo Kalk Reactor Help.

2Flash1 · Apr 12, 2026

I was gifted a Kalk Reactor (Geo) it’s about 15 plus yrs old.

I’m in the middle of ordering new seals and parts.
I DO NOT like the idea it uses a Maxi Jet as seems like it’s not a good seal as well and it’s already leaking is there a more permanent solution?
Unless I can add silicone to make a better seal. For service would suck when I need to change or clean out impeller.

I run a Geo Kalk reactor and can hopefully offer some input. Can you show me some pics, please? Here's mine and the pump:

Pardon the craziness and the mess.

Maybe, with a little creative plumbing, we can upgrade your pump.

You were the tag I was going to tag.

As mentioned, a picture of the pump and setup would help. As a collective, we can hopefully find a pump that is better in fit and performance.

What’s everyone’s thoughts on the Uni Seals? Or has anyone changed them out?

Uniseals work just fine for this application and are easy to swap out.

As for the pump, that is way too powerful. I would go with this:

Syncra Silent 1.0 Pump (251 GPH)

Why does BRS recommend this? The Syncra Silent line of pumps come in many different sizes and will fit most tank needs. Sicce uses high quality magnets in their pumps, which allows them to spin smoother with less noise than almost all other pumps in their price category. If your tank needs a...
