DIY CO2 regulation system

760 Views 3 Replies 3 Participants Last post by  thjones.75
I am new to planted aquariums. I am thinking about adding live plants to my 75 gallon aquarium in my family room. Possibly in the future adding a another planted aquarium right next it. Would this regulator on Ebay be a good piece of hardware for a DIY CO2 system for multiple aquariums?

Here is the title: Matheson stainless steel dual stage regulator model 3813-350

Any comments or suggestions would be greatly appreciated.

IF I got it right.. max outlet pressure is 30psi (ignore gauge)... not recommended if using atomizers.. They run best at 35psi and up..

At $143 for used.. well that is another story as well.. Pretty though..

You are approaching the price for a new brass body 50psi out 2 stage..
About $173.49 inc. shipping..
Would need to add $10 or so for a CGA nipple replacement..
so just say $185

Many thanks for the information and suggestions. I missed some important details on regulators.

I also like the price on the new regulator you suggested.
