New Fluval CO2 Kit
Hi guys,

There's a new all-in-one CO2 kit (similar to the Pierce or ADA Advanced) from Fluval that just came out recently.

It includes:

- Regulator Valve
- 88g Disposable CO2 Cartridge
- Hose
- In-Tank Micro Bubble CO2 Diffuser
- External Bubble Counter
- Hanger Bracket

The good thing is that it uses 88g cartridges. It'll be great if standard 88g paintball cartridges will fit this unit out-of-the-box (which means very cheap and readily available refills). One negative is that it doesn't have a solenoid to conserve CO2 and mainly to prevent overdosing at night.

Fluval products are pretty good quality judging from past experience. I'm seriously considering this for a new Mini-M tank that I'm setting up.

I'd appreciate any thoughts on this.

This kit is nice but 88g cartridges are disposable and not refillable.
There is an adapter for 24oz tanks which reduces the thread to an 88g size.

The cheapest 88g cartridge I got before was $4

How much is this fluval CO2 kit anyway?

Looks like its going to fall in the $70-$80 range.
There's also a smaller kit that uses (i think) 20g cartridges that should be around $30

This Kit looks good, I wouldn't mind this kit if the refills are readily available in petsmart/petco for less than $10 for the 88g.

I wonder how good the needle valve is.

Here's a picture of the refill cartridge:

It looks pretty similar to standard 88g air gun cartridges like these:

The Fluval one costs 14 (so it'll be around $20USD) whereas the air gun cartridges are only $15 for 2.

For a sub-10 gallon tank, how long do you guys think each cartridge will last?

Good question.

I think an 88 gram cartridge would empty very quickly on the 40 gallon tank it claims it can be used in. This might be nice for a small nano tank or maybe even up to a ten or twenty gallon with the 24oz. cylinder, rather than hooking up a CO2 cylinder that is bigger than the tank its being used on.

You can use paint ball refillable CO2 cylinders with this kit if you are considering something small and it also has a solenoid so that if you attach it to a timer it can stop CO2 dosing at night.
but you still have to buy the diffuser, line, bubble counter, and the thread adapter.
They work really well, I've seen them at the ADA shop but they only use them on nano tanks.

I received this kit in the mail last week. I haven't had a chance to use it yet, though (tank is in the process of a dry-start).

Since I'm going for a more Amano-esque look, I decided to ditch the black plastic bubble counter and diffuser and bought some glass ones off eBay instead.

Here is a pic of how it'll be set up on my Mini-M (minus the water):


Stock bubble counter and diffuser:

I actually just picked this up the other day, and I would say I'm pretty impressed with it's components for how stock/basic it is. The one thing I did add was a check-valve between the bubble counter and the diffuser. Other than that, it is working great.

this looks really nice, would really like to get one but its shows out of stock online :(

hockey9999 12-08-2010 06:28 PM

This is now in stock here -

Awesome price too. I hope they aren't making a mistake and advertising the 88g kit by accident.. I would be devastated to say the least if the 20g kit shows up at my door!

I ordered one.

Also, I am still trying to find an adapter suitable for using a paintball tank with this setup.

This looks like it should definitely work! I hope the threads are the same..

I think there may be an option or 2 on this site..

Or this

sailnut 12-12-2010 02:19 AM

I don't think any of these will work.

The 88 gram tank has an odd ball m16 x 1.5 thread.. I spent a lot of time yesterday searching for an adapter with such a thread on the male end with no luck.

hockey9999 12-12-2010 02:23 AM

How were you able to find out the thread size of the Fluval canisters? The threads look identical to the airsource 88g airgun canisters, though I havent tried one yet.

hockey9999 12-12-2010 03:15 AM

Does anyone happen to know what the thread size of a standard paintball tank is? For some reason I can't find it anywhere.. Is it 1/2" npt? If so, these guys may have something that works..

sailnut 12-12-2010 05:23 PM

The Fluval canisters are ordinary 88G paintball tanks. The labeling is a plastic shrink sleeve shrunk onto the canister.
It seems that 100% of the 88G tanks are made with that thread. At least the sites I visited said so.

There seem to be some manufactures that play loose with the length and finish of the threaded neck which makes for compatibility issues.

If you read the Fluval instruction sheet they make oblique mention of this.
