CO2 Supermarket Reviews 

Very quick service and the postage was reasonable.

First class service and quality from a knowledgable team that know their product. Couldn't ask for more.

Very helpful customer support, items arrived quickly as described. Will be using again.

Excellent quality of equipment and all installed in aquarium. Video guides useful

Absolutely brilliant experience with Martin from CO2 Supermarket. His customer service is genuinely impeccable, incredibly helpful, quick to respond, and clearly knowledgeable. He went above and beyond to assist with my setup, answering questions with patience and clarity. Delivery was lightning fast too, and everything arrived in perfect condition. Couldn’t recommend him more, a true example of how customer service should be done

After deciding to install a CO2 system in a newly fully planted aquarium and researching various options I decided to order the Nano system from co2supermarket. The order was placed on-line at the weekend and the kit received well packed in the following week as advised by email.
Instructions for assembling and setting up the kit was readily available on their website and clear to follow.
After only a week of use there is a visible improvement in the condition of the plants which seem to be growing rapidly. Very pleased with the system and have now ordered an adapter to connect to a sodastream co2 cylinder.

I have used CO2 Supermarket for several years now. My most recent contact with them was last week. Customer service/back up/after sales advice is excellent. This makes it very difficult to go elsewhere and I would certainly recommend them.

Great item and Extremely helpful. Definitely happy to deal with them.

Prompt service backed by a quality product.

I had a problem with one part of my order but was resolved quickly with no fuss.
Excellent after sales customer service

Great products and responses! Ordered the SodaStream re-filler and the Quooker one. Had an issue with the SodaStream one (was only half filling the bottles) so I contacted them, they came back within a few minutes with some personalised tips for me.

I had a technical problem and contacted customer service for help. I got a nice friendly, detailed reply which was helpful

Great ordering from these guys items turned up very quickly well packaged and customer service are quick to respond and even check back to make sure everything was OK. Can't fault them what so ever.

Received Ultimate Pro Dual Stage Co2 system on 25/3/25. (Next day after ordering). Excellent quality system, great delivery, easy to setup using inline atomizer, bubbles so small barely visible much better than the German system I had been using for last 4 years. Extremely happy with purchase.
Thank you

Fast great delivery, unlike copy’s on eBay this Soda stream quick release pipe and adaptor worked first time and is a quality product. This is my go to place now for CO2 products.

If like mine your soda stream isn’t giving strong bubbles or won’t stop bubbling it’s the connector not your machine, my Chinese connector 1st lasted 6 months till above issue, 2nd didn’t work at all. Save time and money just go here.

My only comment to CO2 Supermarket is the Chinese version has a useful tank pressure gauge, can you adapt yours for next time?

Amazing product, I was afraid of going down the route of filling my own CO2 cartridges but the adapter sold made it super easy to do. Great product!
