Has anyone ever heard of these CO2 systems or used them before, because a friend of mine has sparked an interest seeing as i could obtain one for fifty dollars, and it seems like a better investment than spending 300 on a good pressurized system that would take a lot more work

After replacing the block, the electrodes, and all the other stuff that "wears out", you'll end up spending almost the same as you would for a pressurized system and it's nowhere near as good as a pressurized system.

I would like to see the receipt from anyone who was able to buy a regulator, needle valve, diffuser, check valve, tubing, CO2 presurized cylinder, and fill this cylider with CO2 for $150. I dont think that is possible unless you go with Wal-mart parts and they are going to stop working in a year. A good qualitey pressurized CO2 system wont run any less than $225 and thats pushing it IMO.

I bought one of these and it fell under the category of "Worst purchase I have made for my tank"

I had it on my 75 gallon tank and it was worthless for that size tank. Now on a smaller it might work but the replacement carbon blocks were like $50. And the holder really starts to look like hell before the block is done. The best thing about it in my opinion were the suction cups I took off of it after I took it out of my tank.

5# co2 tank $50
co2 fill $12
all in one reg $65
co2 resistant tubing from lowes 8 cents/foot $1

$128 Thats the minimum if you bubble it into a powerhead/ canister filter.

If you have to buy a powerhead, add $20

If you do as I did and put a rena micro bubbler in the powerhead's pre-filter add $4 for the micro bubbler.

If you paying s&h to a few places add $25

$177 still good for cheap setup that work fine.

If you feel the need to use precision quality parts than yeah, probably $250.

The nice thing about pressurized is the only cost after setup basically is just co2 fill, which is usually pretty cheap, especially with larger tanks.

Good luck.

All US prices of course. You will pay more in Canada.

Do you think a paintball Co2 canister would work for a fish tank application, and if so how long do you think a 20 oz canister would last me between refills
Yes it would work, but you'll save money if you go for a regular-sized setup.

If you're adamant about a paintball setup, Google for Red Sea Paintball CO2 for a Red Sea system or contact Rex Grigg for a nano setup. I'm not sure if he's carrying/providing it anymore though.
