DIY CO2 system bottles exploded.....

Okay so, up untill now, my co2 system was hooked up to my aquarium pump, doing a pretty good job, but the tank is in my bedroom and it sounds like the tank is constantly farting, my girlfriend didn't like it too much, so i went out and bought a diffuser...

This one to be exact:

I left it on overnight and had the scare of my life when the bottle just blew up like a plastic balloon.... I am using 4x 1.3 gallon(5 liter) bottles.
they look a little bit like this:

Is it normal these things only work for pressurized CO2?

the diffuser was quite expensive, it'd be a waste to just have it laying around unused and going back to the farting system...

Your best bet is to spend about $150-200 on a real pressurized co2 system with a regulator.

I know it's expensive, but it is worth it over time.

Also, it is a really cool piece of hardware to own for your tank, imo

Somewhere along the line the cracking pressure of the diffuser was greater than what your bottles could stand. I would suggest using 2 or 3 liter bottles made specifically for carbonated beverages. Either that or a different diffuser. Check the link in my sig for ideas

At one point I had a JBL Florapro BioCo2 system. It is specifically made for a ceramic diffuser and comes with a very sturdy DIY bottle. It is also a lot cheaper then pressurised CO2.

Maybe you can find one on eBay as you just need the bottle.

Definitely use a soda bottle, I used a water bottle as a diy bubble counter and it exploded, so use a bottle designed for,pressure

Champagne bottles will hold lots of pressure. A Methuselah would be about the right size.



Or, you could use a http://www.amazon.com/gp/product/B0002DI1W4?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00. Put the ceramic diffuser away for the day when you go for compressed CO2.

You need a bottle designed to handle pressure. A soda or wine bottle will work great. I have used both with no problems.

with ceramic diffuser you may not have enough pressure in the co2 system to handle it properly. You will be always fighting the high pressure thing, with risk to get an explosion.
build a reactor given you are having a canister filter, and all problems solved, even if you later switch to pressurized CO2.
a reactor can be maid under $20 or so.
