Re: FFF
This is not so far off. I know we can debate till the cows come home how
unimportant actual pH is since it varies in the natural wild habitat along
with photosynthesis and co2 usage. In the limited confines of my home
aquariums, I have noticed ph has significant affect on the character and
behavior of fish. An example was my attempts at breeding some A. viejitas.
Even though the hardness was not much more than 30-40 ppm, I couldn't get
consistent good parental behavior before I started adding acid, forcing the
ph around 6.0.
In another tank where I routinely add co2 and rarely ever test _anything_
anymore, I noticed the fish were all hanging at the top one day, rather
lackadaisical and not looking happy. Normally they swim around some, but not
necessarily near the surface, nor are they motionless. I know that water
tends to become acidic with nitrification, and I had recently added a fresh
co2 bottle (which just inspired some pearling on the plants, it wasn't
excessive due to a biowheel). This would have further lowered the ph some
with the added co2. I checked, and the pH was somewhere at or below 6. I
threw in about a teaspoon of baking soda, made no other changes, and within
about 1/2 hour the fish were back to their usual behavior.
I can easily see where there could be a correlation here.
Just my 1 cent.
