Hi there, Just wanted to ad that I have JUST finished putting a CO2 system together based on this thread. I used;
*an aluminum #5 CO2 canister (cost 75$ e-bay, 15$ to fill)...something I did not know when I bought it is that it will have to have a date stamp on it for many places to refil it, so check on that.
*a Victor single stage, dual gauge regulator like the one in the diagram at the beggining of this thread (cost 180$ on e-bay, only found the price goes up from there).
*an Ideal needle valve (cost 70$ aquariumplants.com)
*Burkerk Solinoid (cost 50$ from aquariumplants.com has to be fitted with power cable so check that)
*Aqua Medic Bubble counter (cost 30$ aquariumplants.com mine leakes, ordered one for 20$ that looks a lot better from greenleafaquariums.com)
*Aqua Medic CO2 reactor (cost 120$ aquariumplants.com)
*Mag Drive Pump @ 500 GPH (cost 80$ aquariumplants.com) **this was not mentioned in the original thread that I could find, but you will of course need a pump of some sort. I think some caister filters might be able to handle the load but I would suggest you look into that 1st.
I've done the math for you, I spent 600$ to put this together not including tubing, teflon tape, brass fittings, some screws and little things like that that prolly added another 30-40$ to the cost. I took me two days to make sure I had all of the leaks sealed tight. The bubble counter leaks very very slowly but I have ordered a replacement and that problem should be taken care of very soon. I mounted everything under the stand of my 75 gallon aqaurium so only two 5/8" clear tubes are visible and the uptake has a sponge filter. I also ordered a Drop counter when I ordered the replacement Bubble Counter as I feel after spending the cash I have I want to know precicsely what it is doing and how well. I will update here on what this does for my planted aquarium in a couple weeks, but I wanted to put as much info here as I could think of for anyone about to try this for the first time...It is time consumimg to determine what you'll need and costly to put it all together. I spent about 3-4 weeks just researching before I purchased any equipment and it was difficult to find and put it all together but this particular thread was THE blueprint that I used to build my CO2 system. Good luck!
and THANK YOU Darkblade48!!!
I'll try to ad some pics this week just so you can see what it all looks like.
