Co2 system is been a pain

Ok, so I purchased a basic Co2 system (pressurised) got it all set up and working just had to turn the on/off valve off at night on at day, but as I am at work when the lights come on I got a solenoid and fitted that to the Co2 tank, the issue is, i set it to 2bps and then I got to bed, I get up and its all off as it should be then go to work go about my day, come home and I am getting may 1 bubble every 2 seconds, the only thing that could be at fault is the solenoid as it was working fine before. has anyone ever come across this? is it an issue I can fix?

Thanks for any info.

I will keep an eye out for this, but as I have used jointing compound it is unlikely, though not impossible. Any other suggestion would be greatly appreciated.

ok i think i have fixed it, when i bolted the solenoid on the bottle was in the way so it sat at and angle, I have managed to get it straight and just turned the aquarium on and off 3 times over the last hour and every time it works properly. Maybe the angle was causing an issue of some sort?

Ok, so the solenoid is now kicking on and off nicely, seems to be working correctly, new issue has arose though but this is an issue of my causing. when fitting a solenoid don't do what I did, fir the solenoid between the bottle and regulator, I couldn't do this due to the type of regulator I bought, so I ended up bolting the solenoid onto the "out port" of the regulator, what this does though is when the solenoid opens it dumps all that pressure straight into the tank, this is because there is nothing regulating the pressure. so now i need a regulator to bolt onto the solenoid. Does anyone know of any cheap ones available, as I am not willing to spend the £50 I keep seeing.... by air compressor for my air tools didn't even cost that so can not justify it for what is essentially a tap.

Yes it is, it goes, bottle re solenoid, the pressure builds over night then when it turns on with the lights it releases a lot of bubbles then slows right down to my desired level

after I believe, couldn't get it before different connector and god knows what I have lol

heres a picture

my mistake, I have not got a needle valve, that's most likely the problem, can get them for less than a tenner though so thats good.
