Are carbon doser v1 any good ?

Hello.
I’m about to jump into a calcium reactor in about 6 months. Boun gave me a carbon doser v1. After checking it out. The solenoid is bad. I can rebuild it. I’m just wondering if it’s worth the effort, time and money or they not very good. As I don’t have much experience with them.
 
Curious, how much do you think it will cost to rebuild? From my understanding the way these control bubble count is by opening and closing the solenoid which isn't quite as good as a good needle valve.
 
I have four Carbon Dosers (various revisions of the "V1") in service, the longest has been running for 7ish years. A dual stage regular is generally better, but I personally haven't seen the need for me to change yet.

Would I repair one? Sure depending on cost.
 
I took it apart. It’s actually pretty simple design. I think I can do it on the cheap. Just don’t know if it was worth the effort as it’s an older design. I would hate to be into it for a hundred and a bunch of hours just to find out there’s a flaw in the design
 
Sorry to derail the thread, but any reason for going to a dumb carx from an automatic carx?
dastaco left the US business so parts are hard to get. i did manage to get a few spare parts to make the carx another year or 2 or 3, but who knows what will happen afterwards. even though i like the dastaco system, it also crashed my system and when you lose thousands of dollars of high end sps, you look into an alternative to protect your investment.
 
I was looking at the Deltec automatic reactors - seems they don't use a PH probe which is pretty appealing since PH probes are junk and drift a lot?
