This is my first pressurised co2 use. I have a flex 15g and running at about one bubble every 2 seconds on a sov 1 hour before lights on and off. Drop checker contains 20ppm liquid, I'm aiming for 20-25ppm.
As per the pictures the bubbles don't seem to absorb very well. The drop checker is green but is always the same, I can't get lime green and the drop checker stays green all day until the co2 comes on again, will go blue if removed from tank. I did a 50% plus water change today (6am) and it was still green when co2 came on (3pm), surely the water change should of reduced absorbed co2?
I just feel like I'm missing something here.
Thanks
