Solenoid for DIY Citric Acid CO2.

Hey guys. I've been mulling over the idea of turning my empty 20 gallon into a planted tank. I've been researching and I've decided to go with a Citric Acid DIY CO2. I'd like to find a solenoid that I attach to the airline so that I can control it to come on 1 hour before my lights come on and stay going until 1 hour after they shut off. I'm not sure where to start. All I've been able to find so far are the ones that ship from China that require an adapter. I don't want to have to deal with that. If anyone out there could help me out, it would be AWESOME!

Thanks.

 

Here is one.

 

Thanks. How would I hook that up to my airline?

 

Never mind. I just had to read a bit more thanks.

 

With DIY you mI ght not need a solenoid. Ove had DIY CO2 on my tank for 2+ yrs and have never had a problem.

How do you do it? Run it all night? I'd like to have fish but not have them die from lack of Oxygen.

 

@ kiviro I run it all night with a high plant biomass and 4x10k T5HO in my 15 gallon that are I turn on when I get home from work around 1730 and turn off when I go to bed around 0100. My plants start pearling after an hr and within 3 hrs they are covered in microbubble.
Dont buy a cheap regulator or solenoid I just bought a chinese brand called didI regulator and solenoid for my 100 gallon and it.was broken straight out of the box. They will bring a replacement tomorrow when they bring my stand but I definitely wouldnt buy chinese if I wasn't in china.

I only have 2 darios 3 cpds and an Otto (had 3 but 2 died and a barely saved this little guy so he has to be on his own till the 100 gallon is established) with a colony of RCS but ive never had problems with too much CO2.

After about 6 months if your anything like me DIY CO2 won't be enough so try leaving it on 24/7 and keep an eye on uour fish for a few days.

Also how are you diffusing the CO2?

 

I was planning on an in tank bubble diffuser. I have a fluval 206 but it had the ribbed tubing and I'm not sure how I'd do an inline.
