Re: [APD] CO2 angst

Stay away from that pillory!!

I don't do any testing either, for the same reasons.  But, CO2 is  
different, because if you overdose by too much the fish die.  I have  
done it.  I have also run into BBA and  plant growth problems, all  
the while absolutely convinced that when I jacked up the CO2 I saw  
signs of fish distress, so I backed off.   I just can't eyeball the  
CO2 and get it anywhere right.

The little "drop tester" is not using a test kit, except for the KH  
kit you need to set the KH of the reference water in it.  After that  
you just glance at it in the tank once in awhile and see if it is  
green, then look to see what the fish are doing.  When I first  
installed it, I was also in the process of increasing CO2 bubble  
rate, being disgusted with the BBA problems.  I apparently went too  
far, but didn't know it until the drop tester fluid was  yellow - 
meaning around 70 ppm of CO2.  I figured it was another false alarm,  
but when I looked at the fish, every last one was at the surface,  
obviously having troubles.  If I had not had the "drop tester" I  
would have backed way back down on the CO2 and forever been afraid to  
try that again.  Instead, I shut off the CO2 and lights, backed off  
slightly on the needle valve, then watched more carefully the next  
day, and had green all day.  Now I have KH=5 water in it and am  
running green again, but at 40 ppm of CO2 with no fish problems at  
all.  And, not a sign of new BBA anywhere yet.

I still don't know my tank water KH, pH, GH, NO2, NO3, ammonia, Fe,  
etc., nor do I care to know them.
