this is my first tank setup as a few of you might know by now. I have a 5lb bottle with a milwaukee regulator/bubble counter and controller. also using a power reactor with a small rio attached. My questions are what do i set the guages at? i know one is the bottle pressure, but what do i set the other at? Also how do i determine the number of bubbles from the counter? Im going to be using this in a 20gal tank. thanks!

Run the low side pressure around 15-20 psi. I would start at a very low bubble rate and keep checking the pH. I assume you know your kH and how to use the pH/kH/CO2 chart. To be on the safe side try not to drop your pH too fast.

I have the very same set up. The instructions for the Milwaukee say to use 10psi, so that's what I used.

If you start at a low rate then you can move up slowly, I began at 1 bubble every 6 seconds (10bpm) and then as the CO2 in the fresh tap water left the tank, I increased the bubble rate to get the pH where I wanted it. I'm at 17 bpm now -- though that will not mean anything to you since my tanks and water are certainly different.

Have you secured the tank properly? I made a velcro strap to tie the unit to the inside of the cabinet.

Oh, that reminds me, I just added glass tops to the tank to fix a moisture problem in the light fixture fans... I need to recheck the CO2 level, that might have increased it.

why is it necessary to strap the co2 tank in? so you dont knock it over?

Right, Should it get knocked over and the regulator busted just right, it becomes a high powered steel projectile.

Hmmm, I wonder how much thrust a 20# co2 tank is capable of producing. Could I strap a half a dozen together and get into orbit?

Seriously, if the regulator broke off at the stem, the most it would do is spin in circles if there's room and the valve is angled just right. If you managed to break the valve assembly off the bottle, that would be a different matter.

Doomer, if what the A-Team has taught us holds true, a 20# bottle can become a very good projectile capable of knocking down bad guys easily. Sorry.. couldn't resist.

Do you guy's use CO2 to keep your water acidic..? I mean, then why do we need peat and other stuff to do that, if we can just use CO2!?

Well the CO2 will cause the water to be more acidic. In my case I could drive my tap water down to under a pH of 5 since I have no hardness in the water. So I have to harden the water which raises the pH and then I inject the CO2 which lowers the pH.

My tank reads 1000psi, assume the area of the neck is approx 1 sq inch, you get 1000 pounds of thrust.

Yes, you must strap it in, particularly if you have cats or kids or earthquakes!
