I have the aquatek deluxe on a 5# tank that I am very happy with. Got it on sale for 85-95 a few years ago. it's 99 on amazon right now

You're just like me. I like to go to bed around 5-6 am and then wake up at 2 pm or so.

If I try to "fix" my schedule to 12 am - 7 or 8 am instead, I get tired by 1 pm anyway, regardless if I am in my room or at work.

In any case, I wouldn't worry about the CO2.

Thanks for the tip, I will definitely do that. I didn't think about the solenoid but it does work quite well.

From what I've read exposure to CO2 can produce effects such as headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure etc, in higher than normal ppm concentration, like 1000-5000 ppm. Anything below 1000 is normally present in any everyday urban environment.

Another guy in Toronto who had the same issue but his went as high as 60 psi. I ended up removing the regulator on the advice of several people aquarium and gas people, and the thing's been sitting on a shelf ever since. Something you want to keep an eye out for.
That would be me. I got a thread on it somewhere here. I also been advise by numerous people not to toy around with something such as a Co2 tank. I really hope you don't either, 80 dollars is not worth the trouble of something going wrong. The very name of the product implies that the pressure should not change that much - it's a "regulator" isn't it?

I brought a Aquatic Life regulator and it been stable with a preset PSI, I think any of the choices of "Aquatek, GLA, etc" will be fine. I think DarkBlade is also making some Dual Stage regulator so you might ask him how much.

What are you using now?

If the pressure continues to rise past the point where the solenoid cannot hold it back, you will probably begin to get leakage.
Or worse, you could get a cylinder flying through your wall like a ballistic misile. I personally wouldn't mess around with it.

I've heard some bad things about the Milwaukee 957, which is why I didn't go with it. Apparently it's quite the hit or miss with it.

I think the problem is that the poppet valve doesn't seal well, or you can call it a "internal leak".
when you set(or a preset) the working/output pressure, that is the pressure the regulator suppose to hold at the output point, no matter solenoid on or off.
when the solenoid off, the seal at inside poppet valve can't stop the slow leak of co2, so output pressure slowly goes up. The slow rising pressure may stop when the output pressure rise to a point that the diaphragm been pushed hard enough and the poppet valve completely sealed/closed. but if not, it just keep going up until solenoid can't hold.
Yes they are preset working pressure regulators. Sounds like a good description of what's most likely happening with these regs. That said, and on the advice of various people; gas experts, aquarists etc, do you feel continuing to use these regs is safe? The one I had rose from 35 to 100 psi, and my friend's rose from 35 to 65 psi after the solenoid went off. I tried examining to see if I could open the regulator, but it seems to be hermetically sealed, and I think the thing would be ruined if I opened it to try and maybe replace the faulty part. Any thoughts?
