    I read an article at CPzine about how to make a CO2 machine here.

    I was wandering does it really help that much? Would it be worth having to grow N. rajah? Or any other Nepenthes for that matter. Oh yeah and Jeff I enjoyed your article on N. rajah : ). Plan on getting one as soon as I can move some of my plants around.

    I tried that and my palnts did pick up growth but I discontinued my use of it as my whole tank was smelly from the Vingar and it was really stinking more after the reaction was bubbling over the sides once in a while and it REALLY stunk then so I actually had to clean my whole tank out and re start it cause of the smell. It does work but I suggest putting the whole setup over/on a drip pan incase it does drip. Then it won't ruin your soil/plant in your are you have placed it.

    I also read this article about a CO2 machine and was wandering if it would work out of water.

    I don't know as that is a setup designed for the use in water. A good idea though!

    yes, the yeast method of making CO2 works for plain terrariums or aquariums. I use them on all my setups (planted aquariums & CP terrariums) except the highland one which has a fan and airconditioner and the Co2 is quickly dissipated so it's not worth it but on my sealed lowland tanks it works great.

    The yeast method doesn't stink either (til you dump it out) because you're basically just brewing grain alcholol with the yeast method. If you'd add hops and some barley when you set it up you can drink it when the Co2 is used up! JK!

    When using the yeast method be sure and dump out the entire contents of the bottle (and rinse) every 21-30 days because the ingredients become inactive after this amount of time. I also like to use 2liter plastic [I]juice bottles[I] (or gallon size gatorade containers) because the plastic is more rigid than 2 liter soda bottles and the bases are flat and far less prone to tipping over.
    Also, do not use glass bottles because the gas is produced unevenly somedays a lot somedays not as much-plastic breathes slightly weheras glass breaks. A wall full of yeast is something wifes and girlfriends get upset about pretty quickly (cos you DO have to repaint)!

    Have fun!

    Swords, as I was reading this, I KNEW you would get to it before me! Darn it!

    I used to inject my 55gal aquarium with a yeast reactor... then one day it tipped, I was in a hurry, so I put it back upright... and it siphoned... oh what a mess....

    long story short.. I went out and bought a professional grade CO2 reactor the next day... much better.

    I am going to drive out to my parents property today, pick it up from storage, and slip the hose into my tank and smile.

    I haven't tried a pressurized CO2 unit before. It would be fantastic for a plant only terrarium or greenhouse but I worry about using pressurized CO2 on a planted aquarium (with fish) because of the number of accidental wipeouts (Ph meter goes bonkers and the CO2 overloads the water), whereas a yeast generator can't make too much to overload the water but as you know-it can screw up and back siphon into the tank (and you can't get the same optimum CO2 level as with the pressurized unit). I store my yeast generators beneath their tanks and if I'm using then on a fish aquarium I add a Tetra check valve between the tank and the bottle to keep the water from mixing with the generator.

    Sword, I am suprised you haven't done more research.

    Co2 can reach saturation levels in the water without displacing oxygen... the reason many aquarists have had 'wipe outs' is because they believed that plants like animals, only respirated one way. Aquatic plants respirate co2 in and oxygen out during the day, but at night, this process is reversed, and they become oxygen users...

    The way to do it is low tech, forget all the fancy ph meters and so on, and just start your flow off nice and slow, super super slow... start working your way up until you start seeing algae form, you should do this over the period of a few months, so your plants can adapt to the new source of nutrients and out compete the algae... once you start seeing algae, back off a little, and youve found the perfect spot.

    Now, you dont even need to turn your Co2 off at night, it's very very cheap to recharge, so leave it running. but at night, stir your tank with a couple air stones to keep everyone happy, put a pump on a timer, on when the lights go out, off when they come on... co2 starts building back up in the water and by 'noon' you will see oxygen saturation occur, in the form of tiny bubbles rising off the leaves of your plants, it's quite an incredible site...

    makes me want to go out and set up my tank again.

    Now, one thing to remember, is I live in San Antonio, with water so hard it requires chewing. Seriously... I can't even measure my water hardness with a test kit, it's off the scale... so no matter how much Co2 I pump in, it doesn't matter...

    another thing to consider, is that PH really DOES NOT MATTER all that much with most fish (yes, some are very sensetive to it) but in a standard mixed tropicals tank, it does not matter. Why? When PH goes south, amonia and other chemicals start reacting differently.... they become detrimental to the fish... forming anoxic pockets, eating away at their slime coating, damaging their gills... but here is the thing, if you keep a really clean tank, and with plants, you have no choice BUT TO KEEP IT CLEAN.... keep it clean with low amonia, and the ph is secondary... it really only matters with the doozies.. like discus and arrowanas...


    you wanna know the kicker? I used to have an arrowana... a beautiful silver... thinking back on it... I think it was getting gill curl BECAUSE of my water quality outof the faucet... someday, when I have a 300 gallon plus... I will get another... fill it with nice water. RO with RO RIGHT, and I will have much fun...

    course... I need to do a reef system next...
