So I have my regulator. The GLA Gro-1. And now I'm wondering what else to go with it. I have decided to put this set up on my 40 gallon and break down my 10 gallon. The 40 is medium light. I use an aqueon HOB for now as filtration. I was planning on renting a co2 tank from a local gas place. The regulator says it has a check valve as part of the regulator in the diagram that came with it. Do I need a check valve? I was planning on getting the GLA atomic diffuser that isn't the in-line one and has the check valve as well. Not sure what size I will need for a 40B. Any suggestions? What drop checker is good? I can't afford a pH probe at the moment. Anything else you can think of that would be helpful? Thanks!

How about the following:

1. Needle valve
2. Bubble counter
3. CO2 Reactor (instead of the diffuser)
4. Solenoid (for timed operation)

No.92 sounds pretty much spot on, however, taking a look at the Gro-1 on GLA's website it looks like it comes with a bubble counter, solenoid, and needle valve as part of the build. If you're satisfied with those parts (and I guess you should be otherwise you wouldn't have purchased) you probably don't need much else.

Maybe another check valve as a backup? Airline/CO2 tubing if you need it. And a timer to run the solenoid so you can turn CO2 on and off with the lights.

Thanks!

Well if your keeping the HOB you'll have to get a power head or something to drive a reactor. Canisters are somewhat better with co2, but you can make the HOB work as long as there's not too much splashing at the surface.

I have a HOB filter at the moment and don't think a co2 reactor works with that correct? I don't plan on upgrading to a canister until the HOB poops out.

Ah thank you! You beat me to my own question.

No, it wouldn't you would need either a canister filter or a power head to move the water through the reactor. The atomic or regular ceramic diffuser will be fine. I've used diffusers on 4 foot tanks without issue.

Thanks. Appreciate it. By the way, all the plants I've got from you are doing great!

I put the 80mm atomic diffuser in my cart and was wondering if that's too big for a 40?

Good to hear, thanks
