I apologise because I'm sure this has been asked before but my search didn't bring anything up. I have been having CO2 problems for weeks, I either get a blue drop checker or a yellow drop checker, every time I try and tweak the CO2 over days it just doesn't budge. Meanwhile all the plants are dying and algae is going ballistic. So for whatever reason its currently very yellow. The fish seem fine, but does that mean they are fine?
It takes 2 days for the drop checker to turn yellow. I've had the tank for 10 years, never had so many problems with the CO2 and would rather keep it yellow so the plants can recover but obviously I have to think about the welfare of the fish.
We live in a hard water area, I don't use RO, I did for years couldn't cope with the waste. So it is what it is. Not sure if its relevant.
