Avast Marine Works K1 Kalk Stirrer

Purchase month, service time:
- Purchased in January 2019
- Started Service in January 2019 so in constant use for about 10 months now.
- Running both a kalkwasser stirrer (Nilsen reactor) was recommended by the Reef Aquarium, Vol 3: Science, Art, & Technology by Julian Sprung & J. Charles Dalbeek.
- I wanted to go with a calcium reactor instead of dosing 2 part. Calcium reactors can lower pH. kalkwasser raises pH.
- When I purchased this, I think this was the only available kalkwasser stirrer on either bulkreefsupply.com & marinedepot.com. My LFS didn’t carry any kalkwasser.
- It’s worked flawlessly for almost 11 months now. When my apex outlet is on, it stirs. When it’s off, it doesn't.
- I can’t hear it at all. Although my aquarium isn’t very quiet.
- The barbed outlet does clog up. A kalkwasser disc forms and it blocks the barb fitting. This means it fills up the tube and leaks out the sides from the top. No big deal if it’s in the sump, but not ideal. Someone online replaced the threaded barb with a regular ½” MPT to a slip/socket which solved the issue. As a fix I put a weekly ‘clean kalkwasser output’ task on my Neptune Apex and all is well. It takes 10 seconds a week. No big deal.
- If the motor assembly on the top screwed off somehow, it’d be nice to be able to check/clean the motor electrics every so often.\
- I have some condensation in the motor assembly I can see through the semi transparent housing and I’d like to pop that housing open and clean/dry everything out. It sounds like it’s assembled with temporary glue, but I couldn’t pop it open with hand strength and didn’t want to use tools to shatter the housing. And all that said, it’s still working reliably after almost a year.
