Twigflinger Posted May 30, 2022 Share Posted May 30, 2022 Has anyone used this? I have had one in the tank for a month or 2. Never seen it actually turn green. More of a bluegreen. I had the bubble counter at several bubbles per second but was afraid to go any higher. Lost 2 neon tetras so i turned it down slightly. The other 2 have been fine the last few weeks. Not sure if the tetras dying was Co2 related, parasites or something else.. I have misplaced the refill liquid so now I am debating getting a different indicator and liquid. Is all liquid the same or are some brands better than others? Link to comment Share on other sites More sharing options...
