First off, let me say, I simply want to understand a few things here, hence I am asking the question, I do not want a flame war.
Working on the "assumption" (I highlight assumption as I do not know what I am about to say as fact, therefore want people opinions as to how correct I am in thinking this) that fish deal with gasses through their gills via osmosis, and that I am working under the assumption that for a fish to rid themselves of co2 the surrounding water has to be of a lower concentration of co2 that their body is at, and this can continue up to a level of co2 concentration which varies for different types and sizes of fish (as evidenced when overdosed co2 previously with angel fish and ancistrus responding extremely badly and neon tetras and platties not seemingly bothered by these levels).
Secondly, would I be right in assuming that agitating the surface of the water increases the rate of co2 drive off from the water column, while also increasing o2 levels?
To kind of draw those two paragraphs together, I have the impression that it is not how much o2 is available to the fish as to whether they can cope with the increase in co2 levels, it is the amount of co2 in the water and in their bodies which determines whether the fish can expel this co2 and thus whether the fish suffer from a lack of oxygen. (Same principle with asthma, the biggest problem is exhaling, as opposed to inhaling which causes the sufferer to experience loss of breath) if the water gets so saturated with co2 that the concentrations are too high for the fish to expel their co2 into the water then the problems start, and it is not a result of low 02?
Bearing in mind, its late (or early depending on your viewpoint) and I have been up all night and my way of explaining myself leaves a lot to be desired, would it be a correct conclusion to suppose that surface agitation of water, simply to enable you to throw more co2 into the water is a bit of a red herring which serves no other purpose than to use more co2 as neccessary (remembering surface agitation draws co2 out of water)
Isn't it better to simply stock with lifestock at the accepted levels taking into account surface area of tank allowing for o2 exchange ensuring their oxygen requirements are met and then just using whatever co2 diffusal method you prefer to achieve the co2 concentration your lifestock seem comfortable with.
Adding further o2 is not needed and nor does it allow higher concentrations of co2 owing to the way a fish deals with gasses?
What do people here think?
