- Aquarium SUS 304 Stainless Steel CO2 Diffuser Widen Hook, DCW300-40

If the tubing slip connector with check valve hadn't been installed backward to prevent CO2 flow and wasn't jammed so hard onto the stainless steel tubing, it would have been a very pleasant installation experience. When I first installed and hooked it up, the bubble counter showed flow, but after a few minutes, the flow stopped. After reviewing all of the photos, I decided to reverse it because there appeared to be an obstruction and all the pictures show the thicker collar at the top. But pulling the plastic ring down while pulling on the stainless steel, it refused to budge. So I got some pliers after it and gripped the plastic ring and the connector and was able to remove it. Sure enough, when reversed 180, the connector easily slid onto the steel tubing and gripped it well. By pulling the plastic down and pulling up on the steel tubing, it was easily removed. After connecting everything up again, I can say it works well.

Quality diffuser, fits my tank well. No leaks.

I've been using CO2 systems in my aquarium for a while. Typically opting for the plastic with cork diffusers, while they do the job they typically have leaks and from my experience become hard to upkeep with appearance. I decided to pick up CLSCEA stainless steel diffuser and it's a gem. Easy to install the connection points have a check valve and tube lock that ensure no CO2 leaks. I'm sure ovee time the ceramic plate will have algae and require some cleaning/replacement. But overall I really love the look. It does give the tank a little modern look so might not be for everyone but I think it really is a nice add.

I love this thing. I have used it for years is strong durability and when I broke it with my own mistakes I brought the same one because for the price and the quality I just love it. Very easy to clean and install

Works great but doea not fit a rimmed tank. I had to cut the rim to make it fit

Super happy with this! It solved the problem I was having with my previous diffusor with the tubing constantly coming loose under pressure, produces really nice fine CO2 bubbles and IMO looks great too. Thanks!

iF IT WORKED, I'm sure it would be great. I've had a different model in the past that just stopped working for the same reasons. I have tried every trick in the book I can think of-- I've submerged it, I've dried it, I've redid the plate, I've changed the plate, I've put it on low pressure, high pressure, insane pressure-- Not a single bubble in over 24 hours. I do not know what magic is used to make this work, but I cannot be bothered. I'll be returning it.

The product works very well, but you have to be vigilant. I tried using it with the same tubing I had connected to my inline CO2 system. Nothing came out; I disassembled it and removed the ceramic disc - still nothing. I blew through the tube, and it was clear. The solution was to submerge the whole unit in water, where I discovered that the inlet connection was loose - the CO2 was leaking out right there. I grabbed a piece of tubing from a spare pump, installed it, and everything worked perfectly.

Looks cute... I've tried everything and haven't gotten a single bubble to come out. Threw the package out and can't figure out how to contact seller.

Great Design product! Works with 1 bar or 15 psi with citric acid and baking soda DIY . For large system: Full bubles with 30 psi /2bar. with the same setup. Awesome. Dont need pressurised co2 bottle. Happy with this product!

Muy buen diseño y funciona mejor que los difusores de vidrio. Muy recomendable

LOVE IT! I will be buying more when it need them :)

Excellent, bubbles are so fine
