Re: [APD] RE: DOC and BGA
In my slow grow tanks, if it looks like things are getting
a bit out of whack, I might test and find the NO3 or PO4 is
way too high or low and do a water change and reset. Or I
might just do the water change -- it's about as easy as
testing since my slow grows are relatively small tanks.
I suppose this marks me as some kind of cheater -- doing
occassional water changes on slow grows but it's an easy
way to deal with water quality, at least for me.
If the DOC is getting high, would that not show up with a
drop in pH do to the formation of acids -- storng buffering
