Really? Not me. I'd go for reactor before controller. I ran for a decade without a controller. If I had to manually dose that long, I'd have shut down long ago. That being said, I would plan the Apex for sure, just not ahead of water chemistry.

ya its a pain to manually dose. Any thoughts on Kalk Wasser ( Spelling)? . Would this be easier?

It's an option. A bit more maintenance than a Ca reactor. Less initial cost. Harder to find bulk (affordable) kalk. Retail stuff is expensive.

I've used both, the reactor is a lot more set and forget.

kalkwasser from J&L is pretty good price.

However I don't know how much you will need per month if it's your only source of dosing.

As my primary dosing is done with calcium reactor, and Kalk reactor is only to top up the extra bit of calcium and keep the pH up.
