For giveaway is one Aquarium Engineering 6" Automatic Calcium Reactor + Replacement CO2 solenoid valve + Spare O-rings.
For those who do not know, Bill Wann ran Aquarium Engineering, until the company, from what I understand, ran into trouble. I was lucky enough to receive my equipment back in May of 2020 when Aquarium Engineering was in business, because this is a very nice reactor, and I have never had a reactor maintain calcium and alkalinity as well as this reactor. But please understand that Aquarium Engineering is no longer in business.
This reactor ran extremely well, until the CO2 solenoid in the automatic controller failed. I also needed a larger reactor, so now I have this old reactor which I feel should be given away, as it technically does not function as intended at this point, and because the parent company is out of business.
I have a replacement solenoid, which is included. If you are are good at wiring, you should have no trouble replacing the solenoid inside the controller. Once replaced, the reactor would work as intended. Moreover, you could also just bypass the CO2 solenoid, or use another method of controlling CO2. The pinch valve inside the controller, which regulates flow, absolutely functions and is amazing at regulating calcium and alkalinity.
I have attached the original instructions to this post. Please note I replaced the tubing shown in the instructions with my own tubing, since I run a large system and color code my tubing. I no longer have the original tubing.
Pickup is in Scarsdale, NY only.
Calcium media is not included. The recirculation pump functions last I checked. The automatic controller powers up and functions, with the exception of the CO2 solenoid. I also have spare o-rings, as the o-ring that comes with the reactor can dry out with disuse.
Photo showing inside of controller. You can see the faulty solenoid.
Replacement solenoid (this is not from Bill Wann. I matched the information on the existing solenoid)
