High Tech CO2 ... Ay, yi, yi
It's a good thing I love this hobby and consider this kind of thing part of the work that goes into growing plants well, and appreciate the additional technical/etc aspects of CO2 injection...
A month ago, for no reason other than boredom, I leak-checked all of my fittings. No leaks, but managed to get Snoop (bubble liquid) into the electrical part of my solenoid valve, which melted down 30 minutes later (smelled the burning) and needed to be replaced. My mistake.
Last week I noticed that my drop checker was much darker blue than normal. Break out my leak detection fluid and what do you know there's a leak at the tubing inlet where I pulled tubing through my DIY bubble counter. So I DIY a new bubble counter. Then I slowly up the CO2 over a 5 day span to tweak it into the right needle valve setting. 2 days ago it was finally where I wanted it.
Home sick from work today, so when the tank lights come on I'm around to take a look. Weird, my drop checkers are both solid blue when normally they're starting to go green around lights on.
Take a look underneath and what do you know, my bubble counter shows zero flow. I unplug my solenoid a few times but nothing. I disconnect one of the two check valves I have between the counter and the reactor, and sure enough the bubble counter goes crazy. I do some testing and narrow down the stoppage to the final check valve going into my reactor.
Lay down a towel, get ready to act fast, and I disconnect the check valve and as water is spraying out (even with filter off...and not enough tubing length for me to "twist it shut" without fear of damaging it...place the 2nd check valve back to the reactor.
Now I have CO2 blasting in but needed to back my needle valve way off and will have to spend another few/several days tweaking it back up again : /
Appreciate any recommendations on long lasting check valves for the tubing, these ones are silver colored brass checks I got from Hong Kong via Ebay, and only 5 months old. Now I'm waiting for the next one to fail shut : /
