Problem with diy co2 system
Been trying to find an answer to this problem but have not found one. Hope this is the place to come to. I ordered a D301 generator on ebay that uses Citric acid and baking soda. After a lot of research I finally found a formula to set the thing up, the directions that came with it looked more than a micro dot than anything else. I mixed up the ingredients in the two bottles and marked them. The setup has a gauge on the acid bottle and a cap unit with a hose going to the soda bottle. My problem is that when I follow the directions and squeeze the acid bottle to get some solution into the other bottle so that it creates co2 I get a reaction and bubbling. The information that I have found says to close the needle valve going out of the soda bottle to allow the pressure to build to 1 to 2 on the gauge. I get the reaction and the bottles actually get so hard that they will not squeeze but the pressure only moves a little bit on the gauge and nowhere near 1. I have tried recharging the system a few times with the same results. I am lost and need help finding a solution. The system is on a 37 gal tank. Thanks for any help or suggestions anyone has. I have been an aquarist for more years than I want to admit but this is the first time trying to do a planted tank.
