    Micro solenoids for CO2 regulators

    Thanks, much appreciated. I see so if the timing is too short the valve won't actuate. That would probably be anything less than 15ms. Think the "on" period depends on the pressure, setup, tubing diameter etc, each setup will be different. Will use a trim pot and adjust the "on" time for my...

    Micro solenoids for CO2 regulators

    The clippard valves in question I believe have a response time of around 10ms. What did you find was a good compromise for the "on" time of the pulse. Shorter the pulse I assume gives you a smaller bubbler and vice versa with a longer "on" time.

    Perfect, thanks Roger.

    Check Valve 5074.010 for Co2

    Hello: Is the Tunze 5074.010 check valve rated/safe to be used for CO2. Would be used to provide CO2 to a diffuser at around 30 p.s.i.

    C02 Vinegar/Baking Soda math question

    More of a temp solution until I get the older co2 hardware in operating condition and upgrade the tank. Need a new needle valve, tank needs to be hydro tested. I am comfortable just using a soda bottle or the fire extinguisher as a vessel. Going to go with the sugar/yeast method and run it...

    C02 Vinegar/Baking Soda math question

    Actually looking at a quick and easy option to provide some co2 for a nano FW planted tank. I have the co2 hardware to do so, but need to have the bottle hydro tested. Thinking I could do something much smaller, am actually think now using the yeast/sugar method and let it free run. Can...

    C02 Vinegar/Baking Soda math question

    Ooops, changed to .16 and yes 75 p.s.i, Gee that is surprising how much pressure. So for example if I tripled the "recipe" and created more co2 would the 0.16 would become .48 and the volume of the container becomes .4 litre for a psi calculation of 432 p.s.i or shouldn't the percentage of co2...

    C02 Vinegar/Baking Soda math question

    Hmm, that seems high, here are the values I used. The container is 1 litre, but I took away 150ml to compensate for the solution.

    C02 Vinegar/Baking Soda math question

    Yes thanks, I am pretty sure the calculator has it right, just not sure. Have a old fire extinguisher that can be unscrewed and refilled (powder type) and wanted to experiment with creating a co2 source, just didn't want to get too crazy with the pressure.

    C02 Vinegar/Baking Soda math question

    The reaction creates C02, according to the instructions 200ml of vinegar and 15 grams of baking soda should create 1 gallon of C02?. I wanted to know the psi if it was compressed into a determined space, the calculator suggest approx. 7 p.s.i with the parameters I provided, or at least I think...

    C02 Vinegar/Baking Soda math question

    Thanks kindly much appreciated. I suppose if one can source some pure acetic acid you would adjust the volume proportionally, but I suppose at some point you are dealing with a slurry as opposed to a solution. If I can pick your brain on one more point. Using the calculator below and if it is...

    C02 Vinegar/Baking Soda math question

    Hello: Ok a bit of topic, but wanted to generate some CO2 and stumbled upon this that is apparently the correct ratio of household vinegar and baking soda to efficiently generate a given amount of C02. But I have access to cleaning vinegar which is 10% acetic acid vs 5%. SO, does this mean I...

    Tunze Nano Osmolator 3152 Pump

    Thanks Roger, good to know. In my experience the pumps last a very long time, unless using Kalkwasser.

    Tunze Nano Osmolator 3152 Pump

    Thanks Roger. turns out I had purchased a spare pump before the 3155 gave up the ghost. So have two new pumps that should last me awhile.
