Β I went through my experience with this 3 in 1. I found it to be hard to take off the diffuser disk, as some may not have the same problem. I finally yanked and yanked to get off the rubber gasket with diffuser. The rubber gasket was a little torn. I finally added water, and for the first few seconds the bubble counter worked. The water in the bubble counter was full as well, but soon half of the water was gone. I possibly ripped something while trying to get the diffuser off which I see as the biggest downfall with this product. Anyway, I'd consider myself experienced with planted aquariums, as I've used yeast and sugar for about 6 years, but was tired of the rank smell, and making the mixture. I'm currently using the Fluval Co2 88 CO2 canister method which I'd say I have mixed feelings on, but it works. I'd recommend this 3 in 1 to try as the check valve works, but I think there needs to be progress made on keeping water in the bubble counter and having the hose feed in at another angle. My experience is shown in the video attachment.24 gallon Nano Current Aquarium Shown:Lighting:Β  Marineland 18-Inch to 24-Inch Aquatic Plant LED Light with Timer right now it's fishless, as I had 7 tetras in there for many many years, but the plants were overgrown, and as I changed the water, I changed too much. Anyway, I'm going to make this a shrimp only aquarium and am adding nitrogen and phosphorous along with my normal plant fertilizers. I'll give this 3 in one another shot, but already ordered the Fluval diffuser which is the standard one that comes with the kit.Β  Fluval Pressurized 88g-CO2 Kit - 3.1 Ounces The Fluval costs 5 dollars and change.To add, if you look at the picture on Amazon, you'll see that there is an attachment which allows the CO2 to enter from the bottom. This part wasn't included with the 15 dollar 3 in 1, which for 15 dollars made of plastic, it should have been. ### ⭐ Doesn't work with CO2 tubing *by C***L on Reviewed in the United States πŸ‡ΊπŸ‡Έ on March 9, 2012* This is a nice little CO2 Diffuser. I had high hopes for it as it has the check valve & the bubble counter built in.The problem is that CO2 tubing is a bit stiffer than regular airline hose which you could use with it. It does seem like it is designed for airline tubing since it has a channel to run the hose through to hold it. There is no way to use this channel with stiffer CO2 tubing. With the CO2 tubing there just is not a good enough seal on the hose connection for it to not leak CO2 from the bottom.My research on CO2 tells me that regular airline, while it works, will deteriorate and you will leach CO2 through it. So you shouldn't use regular airline tubing with CO2.If you are going to use CO2 tubing I recommend looking for devices that have the nut on the inlet to hold the hose on for a good seal. Such as this one:Β  U.P. Aqua Super Atomizer (small) Β which I ordered to replace this one. I'll write up my experience with it when it comes in.If you aren't going to use CO2 tubing this will probably work well. ### ⭐⭐ Did not work for me *by A***Y on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 13, 2014* The product seems to be made well, but the design is flawed. The clip on the side does not fit regular air line or co2 tubing. This means that the tubing will tug on the diffuser and cause it to turn sideways. I would look elsewhere...perhaps try the larger version. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/7411460-aquatek-3-in-1-co2-diffuser-and-bubble-counter-check](https://www.desertcart.in/products/7411460-aquatek-3-in-1-co2-diffuser-and-bubble-counter-check) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-11*
