Most people love a bit of convenience right? I mean look at how popular supermarkets are. Convenience and cheap (nice combo). Outside of supermarkets that lovely combination isn’t so common. But today, I’d like to show you a CO2 diffuser that is.
This rather excellent piece of kit has a diffuser, non return valve AND a bubble counter, all in one neat little package. Made of hard plastic, you can drop it and it’s unlikely to break like glass one’s. If the diffuser plate becomes dirty, we sell replacements so you can do a quick swap (more convenience). CO2 tubing easily pushes onto this diffuser (more convenience). So you can see it really is a great bit of kit with…a lot of convenience
Here’s what David Kearsley had to say about it:
Not only is this one of the better CO2 diffusers I have ever used in regard to creating a fine mist of bubbles, it also includes a bubble counter and non-return value within the diffuser. This means you have only one piece of tubing from the CO2 supply to the diffuser. With regard to the fine mist this took about 2-3 days to settle down and since I have not seen any further large bubbles.
So we know the general idea is to keep as much equipment out of view right? After all no one wants to look at equipment that doesn’t have to be in the tank. Same goes for diffusers and this is why the Neutro Inline Glass Diffuser is so great.
Made with laboratory glass, this inline diffuser comes in 2 sizes – 12mm and 16mm. I recommend placing these diffusers on the outlet pipes – some place them on the inlets for better diffusion but you end up cleaning them more.
To attach it to your tubing, warm it up with a hair drier and it slips on nice and easy. Similarly when it comes to cleaning them (and removal) get a hair drier on it again which makes the tubing easy to remove.
Here’s another YouTube clip for all you folks who prefer to watch videos. It’s one of the best diffusers on the market in my opinion, and like the Easy Aqua atomisers, it produces tiny CO2 bubbles. The Easy Aqua 4 in 1 Super Atomiser is a doddle to set up to, but check out the clip below:
It’s really simple as you can see and made very well too. I know you’re gonna love this one.
This is a really neat and compact atomiser which has it all. Easy Aqua produce some nice gear and this one is no exception. Below are a few details and why it’s different from a traditional diffuser. Atomisers sure are the way forward.
The Easy Aqua 4 in 1 Super Atomiser has an extremely compact CO2 plate which means that when CO2 is forced through it, the bubbles are really tiny. As a result they ‘hang’ in the water, floating around doing their business. The longer the CO2 stays in contact with the water, the more it’s absorbed. This means you need less CO2 and makes having a decent ceramic plate all the more important. Traditional (cheaper) diffusers have basic ceramic plates. CO2 can be pushed though them very easily but the bubbles are larger and shoot to the surface. This means they aren’t absorbed and you need much more gas. As the bubbles pass through a glass diffuser plate, they can make a high pitch, irritating noise. Because atomisers have a much tighter plate, you don’t get this noise.
The bubble counter is visible on this atomiser so you don’t have to worry about a separate one elsewhere in your tank. Whilst a bubble counter is important, don’t base everything on it – your drop checker is the key to your CO2 levels and if you need to increase the dosage or not. However, it’s a good indication and you know what 2 bubbles a second looks like for example.
The check valve has double safety mechanism so there really is no chance of it not working. CO2 tubing has to be connected to the atomiser by a locking mechanism in order for it to keep it in place.
All in all a great CO2 diffuser and to top it off, if you drop it, it probably won’t break. Result
There are so many diffusers on the market these days it’s probably a hard decision as to which one you should use. The problem is there’s not a great deal between them so this makes your decision even harder. So I’ve decided to focus on just one – it looks great and functions well too and it’s called the AE Design 150L Spiral Glass CO2 Diffuser.
What’s special about this product?
Delightfully manufactured it looks super in the flesh. The ceramic plate is about 2cm wide and made of sufficient quality to allow for small CO2 bubbles to pass through and then circulate around the aquarium. The overall height is about 10cm. What really works well for this product is the spiral which always captures hobbyists eyes. The CO2 bubbles pass from your regulator into the diffuser and then pass up through the glass spiral and this in itself becomes mesmerizing. It’s hard to take your eyes off it…
As you can see, because of the spiral, it doubles up as a bubble counter which means you need one less piece of equipment. This glass diffuser is suitable for aquariums up to 150L but if your tank was a little larger, I don’t think it would cause a problem. Similarly if you have a smaller aquarium and are particularly fond of the spiral (it is nice isn’t it) then you could still use this diffuser. Remember the lower the pressure on your regulator, the less bubbles come out of a ceramic plate. The higher the pressure and bubbles come out of them everywhere.
Keeping diffusers clean:
Cleaning glass diffusers is easy – algae builds up on the plate every couple of weeks so to keep them fresh, soak them in a neat bleach solution over night, and then in the morning give them a thorough rinse under tap water for about a minute making sure it’s nice and clean (and bleach free).
If you have a CO2 glass diffuser then odds are you feel like the bubbles are too big and quite often shoot straight to the top of your tank without diffusing into your planted aquarium.
Many glass diffusers do a good job, but they’re pretty cheap and as a result the ceramic plate used is not the best. Sure it works fine but the bubbles can be on the larger size than you actually want (relatively). Now if you paid, lets say £100 for your diffuser, the ceramic plate would be of a much higher quality and you probably wouldn’t be reading this post. If CO2 bubbles are tiny, not only are they less obvious in your planted aquarium but they also distribute better, after all your sole purpose of having CO2 in your tank is so that it spreads over everything and your plants absorb as much as they can.
With CO2 bubbles that are too big, they have a tendency to shoot to the surface of the tank and not get pushed around your aquarium. To remedy this use an AE Design Needle Valve. Simply insert one end of your CO2 tubing into the Needle Valve, and then insert the remainder into the other side. This would then attach directly onto your diffuser. You would now have total control of your Co2 and you will be able to produce much smaller bubbles than you were before hand. The valve on this piece of equipment is subtle and easy to use.
Diffusers are always changing in shape or form and up until recently there were only one or two options for moving gas from bottle to tank. Well now there’s a 3rd and it comes in the form of an UP Inline CO2 Diffuser.
Designed to work with external filters only, you attach them inline so that they sit on the outflow pipe. This is a very simple and easy way to attach a diffuser – yes you have to turn your filter off and maybe drain some liquid etc etc but once it’s up and running it means that it’s another item which can be kept out of the tank. The Co2 tube coming from your regulator also attaches to the diffuser on the top left hand side (see image).
The more equipment that stays out of the tank, the more you can concentrate on what your aquascape actally looks like.
Have you ever wanted better CO2 diffusion into your planted aquarium but never really got the results from glass diffusers?
Well now is the time to change to our new Easy Aqua Super Mist Diffuser. They are quite incredible and we have never seen so many small CO2 bubbles from such a small area. It’s done by creating a surface that is so compact that pressurised CO2 literally has to be forced out through the tiny pores on it. This makes your gas a lot more economical when using a Super Mist Diffuser compared to a glass diffuser. You see the smaller the bubble, the larger the surface area (relatively). Therefore if you are creating thousands of tiny bubbles compared to hundreds of larger one’s, the smaller type win hands down.
This diffuser is only suitable for use with pressurised CO2 and you also need to have about 2 bar pressure. Anything less than that and it won’t cut the mustard.
