CO2 Setup Guide
Pro-SE Series Regulator at a Glance
A - CO2 cylinder connection nut
B - Working pressure adjustment knob
C - High pressure / CO2 cylinder pressure gauge (displays the amount of CO2 in your cylinder). Please note, for most of the time pressure will be at level of 700-900PSI as CO2 is in liquid state. When gauge will start to drop, that means liquid gas has evaporated and you have from couple hours to couple of days left to change the cylinder (depending on your bubble rate).
D - Low pressure / working pressure gauge
E - Bubble counter with integrated check valve
F - Gas flow (bubble rate) adjustments precision needle valve
G - Solenoid valve compatible with most pH controllers and electric timers
Step 1 | Washer Installation
Place washer between CO2 cylinder outlet and regulator's stem (inside regulator's nut)
Step 2 | Tighten the regulator
Tighten the regulator to your CO2 cylinder using a spanner or wrench
Step 3 | Bubble counter installation
A - Remove top cap and fill bubble counter with water*
B - Feed tubing through the collar and install cap back onto the bubble counter (detailed bubble counter tutorial)
*We do not recommend mineral oil as it may contaminate your diffuser.
Step 4 | Pressurising the regulator
A - Open main CO2 cylinder valve
B - Adjust working pressure to desire level* by turning front knob clockwise
1 - Reactors 10-20PSI*
2 - Ceramic and Basic diffusers 20-30PSI*
3 - High pressure atomizers (inline & bazooka) 30-40PSI*
Step 5 | Fine tuning bubble rate
A - Plug the solenoid into a power outlet socket
B - Start turning the needle valve anticlockwise to achieve the desired bubble rate.
Please allow 5-30seconds for pressure to stabilise between adjustments.
Monitor your bubble rate for the first two days and fine tune to achieve desire flow.
Do not adjust the flow right after solenoid is powered up. Please wait at least 30minutes before further adjustments.
After each regulator installation, follow steps from below video to make sure your system is leak-proof.

Premium quality product which has an unparalleled affordability compared to most other aquarium dual stage regulators. This is by far the easiest option to buy if you are considering adding co2 to an aquarium

Great kit with everything you need! Really easy to set up and within an hour I saw my plants pearling! Can't wait to see the progress in a few weeks! Thanks for the speedy delivery!

I put off using CO2 for a long time as it all seemed overwhelming. After feeling frustrated with the slow growth of my plants, I finally decided to take the plunge and buy this kit, plus a 2kg CO2 fire extinguisher locally for £12. That was literally all I needed. I watched a few YouTube videos on how to connect everything while waiting for the kit to arrive, and had it all set up and running in about 15 minutes (with great support from Aquarium Gardens - thanks to Dave for his patience with my phone calls!) I got the large diffuser as I have a 240 litre tank - I was concerned it might not distribute properly in a tank this size but I placed it under a cheap Hydor Koralia nano powerhead and that's done the trick. The equipment is excellent quality and actually slightly cheaper than buying everything separately. 2.5 weeks in and it is running beautifully. My plants have exploded in growth, the difference is amazing and my fish are all fine. It's all been so much easier than I expected. If you are thinking of CO2 but feeling uncertain how to get started, I highly recommend this as a simple all-in-one kit.

This is a simple, easy and excellent priced CO2 kit. I have a 125 liter tank with many live plants and can already see the benefits. The equipment is easy to set up (although me being a novice, instructions would of helped). I purchased the Sodastream attachment which works perfectly. I would 100% recommend this, its all there and no messing around finding all the individual components. Delivery was quick and on time. Will definitely use AG again, Thanks

Really pleased with the CO2 Kit. Price was great, I priced the parts separately and this set was cheaper. Found it was really easy to set up and I use mine with a fire extinguisher which it fits to perfectly. All the parts felt sturdy and of a good quality. I bought an extra check valve to go with the set but I think it was probably un-necessary as the bubble counter has one. As a first time buyer I felt aquarium gardens were really easy to shop with and helped me when I needed to double check something. Postage was reasonable and the kit arrived quickly. Look forward to shopping with them again.
