Are there any downsides to using the setup you are mentioning in a 4 gallon? With the 88g regulator?

I wouldn't think so.

To be honest, this is my first experience with using co2 so I am not the best person to answer that question.

I plan to use it in my Fluval Ebi which is 8 gallons..

I remember Cento was concerned with the regulator being able to handle the pressure from a bigger tank.

According to this site, the pressure in any co2 canister, regardless of size, is the same. And the only factor that can change pressure is temperature.

I'm confused. I thought the goal here was to adapt to something other than than the fluval cartridge? It looks like you've built an adapter to get from the fluval regulator to the fluval 88g cartridge. Also, it looks like the fitting you used on the cartridge doesn't have a pin so I'm not sure how the co2 is going to get out of the cartridge. Please explain.

Here is what I got.

Watts A-183 3/8" Flare MIP - 3/8" MIP
Watts A-760 3/8" coupling
Watts A-776 3/8" male to 1/8" female

In hind-sight I should have gotten a right angle 3/8" to 1/8" adapter or 3/8" coupling so I'll exchange it, but that's just for cosmetic reasons.

Cost - $8.41 with tax.

And the result...!

It forms a nice tight seal with the o-ring in the regulator. Now, with a 1/8" male - 1/8" male fitting, some teflon tape, a paintball ASA and paintball tank, I am 99% confident that this will work!

Just as a test, you can see that the Fluval canister screws right into the Watts A-760 3/8" coupling.

Well I havent purchased everything yet, so I can see the cause for your confusion.

The last picture of the Fluval canister and brass fitting was simply to show how well that size brass fitting worked, that being a 3/8" female coupler, but the Watts A-183 3/8" Flare MIP - 3/8" MIP fits quite nice in the regulator.

The missing piece of the puzzle is something like I posted in this post - http://www.plantedtank.net/forums/eq...ml#post1238562

Either a paintball air source adapter that will connect to the 1/8" reducer via an 1/8" male to 1/8" male brass fitting, or by using a paintball remote system, which has hoses that are terminated with 1/8" male fittings that usually screw into a quick disconnect valve on one and, and an on/off air source adapter on the other..

I hope that makes sense, but check out my previous post that I linked to above for pictures of the missing items I am talking about.

I get it! You'll run the paintball tank with an on/off valve via hard plumbing or remote ot the fluval. Cool idea.

I just found an old paintball air source adapter from my paintball days, so now I just need to find a tank, get it filled, and do some leak testing!

Keep in mind that the only piece from my list of brass fittings that is an absolute must is the Watts A-183 3/8" Flare MIP - 3/8" MIP.

Everything else should be able to be put together to your liking, as long as it terminates in a female 1/8" fitting.

I will update you guys in a few hours once I find a tank..

So here is the finished product!


photo by dougjacobs99, on Flickr

Unfortunately it is attached to an old 20oz paintball canister (dated 2/97 lol). I will get a new one this afternoon.

The only additional thing I purchased at Home Depot was a Watts A-716 1/8" MIP x 1-1/2" male-male fitting.

The only thing I don't have a part number for is the 90 fitting, I had it laying around. It is a 1/8" male to 1/8" female fitting.

All of the part's that I used, less the 90 fitting and air source adapter are as follows:

Total cost was about $10 at Home Depot-

Watts A-183 3/8" Flare MIP - 3/8" MIP
Watts A-760 3/8" female - female coupling
Watts A-776 3/8" male to 1/8" female
Watts A-716 1/8" MIP x 1-1/2" male - male
Teflon Tape

On a side not, and as best as I can tell without disassembling the regulator, the nipple that the co2 hose connects to on the regulator appears to be 1/8" as well. With that said, there should be no reason that you couldn't remove the nipple, swap it out for another Watts A-716 fitting, and install a solenoid. I only mention it because I know some of you were posting about it in the solenoid thread.

That looks so good that Im thinking about selling the erg I just bought on eBay, shipped this morning, and building that setup. The cost would end up similar, but the size of that is just so much better for my small tank and small space.

Hmmmm

Nice! A very similar arrangement could adapt to a CGA-320 as well for those looking for a 5lb tank solution.

I haven't actually put any co2 through it yet, I don't anticipate there being any leaks but I will know for sure soon!

I figure though, a 20oz tank is about 6.5x larger then the 88g canister and you can get it filled for like $5 or so.. On my 8g Ebi, I bet I can at least get over a month out of it.

This is probably going to make someone at Fluval pretty angry! I bet they were counting on making their money on the refills!
