Question

DIY Co2 Pressurized Kit


Has anyone used a pressurized kit like this 1? It is to be used with soda bottles. Thinking of buying 1.

Please do buy one of those kits, then use it and let us know how it works out for you. It is an interesting idea and if it works ok it would improve DIY CO2 a lot. I would worry about making a huge mess if a bottle fails from the pressure, but theoretically it won't fail.

It is an Ebay listing, which I ironically found it on this web site. When I am longed I can not view pictures. Thus I search when not logged in to view pictures. On thread on champagne DIY Co2 not longed in there was a link to it. Just go to ebay and search for DIY CO2 system Kit. Then item from a few sellers should be viewable.

I am going to try the traditional DIY Co2 first before buying it.

It says you must prepare -
2x 2 Litre of Coka Cola plastic bottle
1x 200g of Citric acid or 200ml of vinegar
1x 200g of baking soda
With listing lowest price the 1st has detailed instructions. The 2nd 1 has a video showing the preparation of the mixture.

The smell of vinegar would probably not be good. Thus another reason to try champagne yeast 1st. It has a sweeter smell to it. I have a sensitive nose.

I bought 3 of those caps. I didn't see one with the gauge and valve, that would be cool. The caps work great with no air leaks and tight fittings.

i saw a similar kit ( Item number 160968124282 ) from the same seller with a pressure relief on it that would make it even better you could set the pressure and control the bubble count if the pressure builds up too much the relief lets out the pressure.

Use this link: http://www.aquaticquotient.com/forum...user-Generator But, it never gets around to saying how long a batch works. If it is a week, that's very usable. If it is a day, it isn't usable at all. I'm tempted to buy a kit and at least test it. The price isn't bad, but it comes from Hong Kong. I think I would use a check valve with it to stop tank water from flowing back into the bottles.

This one is more expensive, but much neater and appears to be more rugged, plus having the relief valve for safety. I wish it had a check valve on the outlet to the diffuser too. It is on Ebay too.

It has a gauge + needle valve + relief valve + tubing kit. Thus it looks like it could be hooked up to a timer.

I have that exact one. The gauge doesn't work, but I am getting bubbles from my 3 in 1 diffuser. I use that and a hagen nutrifin in a 65 gallon tank. It has been 2 weeks, and I see growth. My angel/baby tears are dying, but my dwarve angel tears are definately growing. My Co2 long term tester is greenish blue, but not the green that it recommends. A side note is that I use a large air pump for my sandfall, and a HOB filter.

The ebay seller has been reluctant on sending me a replacement gauge. It looks like everything else works fine though.

How often do you have to replace the solutions in the bottles?

I would like to see a pic of the tank, angel tears and sand fall.

Strange that 1-typ of baby tears is growing and not the area. Perhaps water flow and Co2 is different for each due to their position in the tank.

Sand flow sounds interesting. Does it give the appearance of water flowing?
