    Simple DIY Oxygenator Tablet

    Was thinking of a good, fast way to raise O2 levels in hypoxic conditions. Came up with a simple oxygenator plan.

    Its made of two bottle caps, some hot glue, and a strip of airline tubing. Just drop one in for instant oxygenation, although this is NOT recommended for long-term use.

    Okay: down to how it works. This oxygenator slowly doses hydrogen peroxide(h2o2) into the tank, acting as a potent oxygen doner. Due to osmosis, the water in the tank tries to equalize itself, so it sucks hydrogen peroxide (slowly) into the tank.

    Heres how to make one of your own.
    You'll need:
    2 clean bottle caps
    2 cm of clear airline tubing
    Hot glue gun
    3% or 6% hydrogen peroxide

    Step 1:
    Find 2 clean bottle caps that are different colors

    Step 2:
    Hot glue them together, making sure there are no leaks.

    Step 3:
    Drill a hole in one side so the airline tubing can fit tightly

    Step 4: Slip the airline tubing in, and seal the edges with hot glue.

    Now your done! To fill it with peroxide, use a pipette. As a demo, this was filled with dye to show the timed-release of oxygen donor.

    Too slow to help out in deadly hypoxic conditions. Also in power outage, this would definetely come in handy, right?

    Wow! That really is an amazing idea. It has been the bane of my existance worrying about what to do if the electricity goes out too long. Happened once before and I lost a quarter of my fish before I found a battery operated fan to stir up the surface some.

    We've had power outages that have been hours long (overnight once, and about 12 hours another time) and I've also had a fish tank completely unplugged for about 14 hours. I'd just stir the surface occassionally, never had any trouble.

    Yea, it wasn't so bad in Georgia, but up here where we live in Colorado (9600+ ft) the air has so little 'air' in it that we have to run extra bubblers to keep enough transfer, and therfore electic loss can really be a problem if it exceeds 6-10 hours.

    Great idea! I like the mix of chemistry and DIY. Makes a change

    Thanks,
