I posted this in the club forum but thought I'd post it here as well since it's relevant to my build:
Just wanted to post this up because we always hear about the negative experiences with companies, but don't often hear the good ones. I bought a used aquariumplants.com CO2 regulator along with a calcium reactor several months ago and finally got around to setting it up with my new build last month. after a couple of days I noticed that I was getting inconsistent CO2 dosing into my reactor, sometimes it would dispense at the set rate and other times it would just send a flood of CO2. I emailed customer service to see if the unit was serviceable and was contacted by Mark over the phone who got some detailed information about the regulator. Even thought the unit was second hand and was obviously an older model that was out of warranty he offered to repair the regulator for a nominal fee of $50 which they normally only offer to original owners after the factory warranty has expired. I shipped the regulator to them and UPS apparently thought the box was a football so when it arrived the plastic housing of the control unit was smashed an broken off the regulator and the low pressure gauge was busted as well. after checking what was left of the control box it was determined that saltwater had slipped past the worn out check valve shorting out the electronic regulator prior to me buying it. Rather than trying to fix the existing one (since it was smashed) They replaced the entire electronic module with a brand new one and for only $20 more installed a new low pressure gauge as well. I picked up one of their high quality check valves to make sure this didn't happen again and Mark even threw in a redundant check valve for free to be absolutely sure this wouldn't happen again! In the end I essentially have a new regulator for $70. Mark could have easily said that the unit had obviously been abused and I would need to purchase a new one at full retail price but instead he stood behind his product as the most reliable regulator on the planet and made things right! AquariumPlants.com will definitely be getting my return business in the future!
