I am new to CO2 injection. I am using a 20 gal tank to grow plants for my 90 gal tank. Using a fulval 90 g bottle connected to a valve/solonoid connected to a ph monitor. what keeps happening is the tubing from the bubble counter keeps bursting . not coming off the connector, it blows a hole in the tubing. sometime the tube pops of the difuser, but, not often. Only one or two bubbles a second. The tubing has burst holes in a couple of other places as well. I got tubing from amazon that is supposed to co2 resistant, but, not working. what is the best tubing to use ?
