I bought a generic drop checker online which came with its own solution. I ran out of it recently and with this week's water change, I replaced the solution with API's pH solution and 4dkh.
Am I doing something wrong? The old solution would be yellowish green when added to the 4dkh water. The pH solution is a true blue when added to the 4dkh. When I test the tap water, the solution still reads 7.4 pH (which is correct). Now, after hours of being in the water with the co2 on, the drop checker is green with a hint of blue. It used to be green/yellow at this same level.
What am I doing wrong? Do I need to up the co2 or is the pH solution inaccurate? Or was the solution I began with inaccurate? Nothing other than the solution has changed. There are no crack in the DC glass, the co2 is on a timer and I haven't touched it or the needle valve.
I am having algae issues still, so I think I may have too little co2, but I don't know. I am so confused........HELP!
