Two tanks off one regulator?

As the title says, does anyone do this? I am building a concoa right now and want to run two tanks off of it. Most likely I will have it split with a T. One solenoid and needle valve for each tank. Also, related to my setup, how long can the tubing be? Reason I ask is because I want to store the CO2 tank in the basement and run the lines up to the aquariums. I would say the tubing would be no longer than 8-10 feet. One tank will be a 55g (upgrading to a 90g cube next summer/fall). The other is a 40b that I am starting to set up now. Thanks for any help and advice.

Yeah, that's all fine. But unless you want to run them on two different schedules, you'd only need 1 solenoid.

solenoid > tee > 2xnv

No worries on the tubing length. If it were much longer, you might want to put one of the nv's inline, just to minimize the length of time for flow changes to stabilize (only a potential issue when adjusting). But it's not a big deal - you can keep the nv's at the reg if you want and run a hundred feet of tubing.

Nice. They will be on the same schedule, just in different rooms. I didn't even think about needing only one solenoid. I tried to search for someone that does this but couldn't find much. Thanks.

Here's a quick pic of mine. Awaiting new parts to rebuild it. I had it running two lines across the room (along the walls) to each tank.

I saw that photo a while back and for the life of me couldn't find it again. And yes, exactly like that. Thanks!

Sweet! How long is/was your tubing?

45'? I had tanks across my living room. So I just ran it along the walls. Make sure its co2 proof tubing.

The T is on in a weird way right now until I get my other parts. Needs to be taken apart and re-clocked

Shout out to Bettatails, I copy his design.

I have three tanks (40 g, 20 g, and 5 g) running off one regulator, two in the basement and one directly upstairs in the living room. For some reason I never was interested in DIY regulator building so I had GLA put on a triple manifold.

I fed two tanks for a while until I moved one tank where it was not practical to run tubing down the hall. One item that may/may not be a factor on the tubing. Depending on what method you use for diffusers, the tubing can "balloon" quite a bit when you stop the flow over a long length. Not a problem if you are using low pressure like for a reactor versus a ceramic disk. Just something to consider when placing the needle valves and solenoid.
The ballooning can make watching a bubble counter to set flow a real puzzle.

Both will be getting reactors. One with a Rex Griggs and I haven't decided on the other yet. I may stick with a Rex or try out a Cerges so that I have built both.

Wow. Now I have full confidence in running mine. My wife will be happy that I won't have to build a new reg.

Yeah. He and Oldpunk make/made nice regs. I can follow the basic design, but not the same parts. Too expensive for me. I will be going with Fabco with the bubble counters (maybe). I may not use the counters. I am not planning on using a controller.

Nice. I remember seeing a pic of Oldpunk building one with a manifold

If you decide to switch to a pH controller per tank, you'll need two solenoids.

It's CO2. See-Oh-Two. Not C02 (see-zero-two).

I purchased a regular aquariumplants.com regulator and then oldpunk (poster here) made me a 40 dollar splitter into 3. So one co2 outlet became 3. I only use two of those outlets where I inject Co2 on both ends of the tank. This way I make sure that all of the tank gets plenty of co2.
