I'm still learning all of this so help me sort this out. First off there is no issue with fish and pH swings despite all the warnings to the contrary. This much I think I have absorbed. Now what I'm getting from what you are saying is that high co2 is not really a problem - the problem is low oxygen. So with high co2 the plants will produce enough oxygen during the day and possibly enough for through the night. If I'm worried that it's not enough for through the night then I can supplement that with a bubbler. This means I can relax and not be measuring the pH all the time and I can ignore the bright red high co2 danger warnings in my "Chuck's CO2 Calculator". Am I getting this right?
I feel like a little like an idiot because this seems like a "no brainer". On the other hand there are so many warnings about pH swings and high co2 that it is a little challenging to absorb what you are saying. Especially when I have a couple gasping fish experiences to back up my fears. Still, I think what you are saying makes sense and I think the times the fish were gasping was before I had the ferts under control and before the plants started pearling.
Thanks for your help, Bill
