The tank hasn't had CO2 at all in the 9 months it's been filled. No CO2, low light, and low fert dosing... it's low tech in practice, even though i have some "high tech" gear (ADA tank, custom LEDs, etc)
Yeah.... getting it fixed is on my ever growing to do list. I need to order a replacement safety valve and then find someone who has a bench vise and stuff to get the valve out... and then whatever kinda glue to put it back in place. That's best case scenario though, there's still a possibility that the regulator has some kind of internal defect or failure and I could need a whole new body...
If there is a local welding shop near you, they would most likely help you out for free. Have you tired looking fleabay for a regulator? Another option is buying one of those beer making regulators and then just adding the post body kit. I think a Micromatic is around 40 - 50 bucks new.
I accidentally dropped one of the harlequins down the drain today. Graaaaaaaaaaaaaaaaah. I'm so mad at myself. I should know better than to move them near the sink... or at least to put the drain covers on... I was so happy about them all surviving quarantine, too. Idiot mistake :'(
