Zerone Co2 Diffuser, Stainless Steel Carbon Dioxide Diffuser Fish Supplies Aquarium Equipment(M250mm)

It to well made, however, the measurements provided for the u section that goes over the rim are wrong. It's about 2cm or about .75in. I didn't even take it out of the bag because it was obviously not going to fit. I got the large version. Returning.

After experiencing some frustration with some other budget diffusers on the market, a friend recommended I give this one a try. I love that you can take apart the housing and clean the diffuser disc and seal, to prevent large bubbles escaping around it. Bubbles aren't quite as fine as some of the high end diffusers, but for the price? It does the job.

Not sure if I need to do something special but as of right now, I'm getting pretty big bubbles through the disk-- not the little bubbles like it's supposed to be. I just turned it on quick to test it-- I'm going to let it run for a bit and see if it changes after more pressure builds up but I'm not very hopeful. I also wish that this came with a replacement disk (oh well...) no instructions were received in package either (not rocket science but it's nice to know that I'm doing it correctly haha)

Won't fit a rimmed tank without a little trimming

Beautiful. Great style. Needed a little priming, but works like a charm.2 months in. It is starting to rust slightly at the cap screw.

The media could not be loaded.  May take a day or two to get such small bubbles so be patient.Awesome product!

This diffuser rusted after less than 2 months. Bubbles were always large…not any better than a cheap disposable air stone. Eventually it also leaked around the edges where it was assembled.

Have a 74 gallon tank worked out greater

The media could not be loaded.  Tienes que dejar hidratar la piedea por 24 horas para que se puedan formar mi ro burbujas, me encanto el diseño, la calidad del productos, recomendable ampliamente

Resistente y bonito.

The media could not be loaded.  For those who write about big bubbles:you do not have patience or do not know how to regulate the correct air flow. Each at the first start gives big bubbles.About the product:Made of high quality material, pleasant to the touch.After purging and adjusting for 5-7 minutes, it gives small bubbles.

Diffuser arrived quickly.I had to tighten it and soak it overnight as there were some larger bubbles escaping, but now the CO2 is a fine mist and is absorbing properly.I like that the ceramic disc is replaceable, and it makes it easier to clean.

c" est bien marché
