[APD] Re: CO2 and BBA

["Bill D" <billinet at comcast_net>]

It would seem that there could be more than one cause of BGA.

In a high tech, high light, nutrient rich environment, insufficient injected
CO2 could well be the causative factor, with all of those added nutrients
floating around and not enough plant growth to make use of them.  An
increase in CO2 would spur the growth of the plants and consume those
nutrients.  But in a lower light, non-CO2 injected, no added nutrients
environment, things would be different.

There the amount of light and the CO2 (or C) level would be constant.  The
only other variable would be the amount of nutrients available.  In a newly
planted tank, before the plants began their growth, BGA and other algae
would take advantage of the temporary surplus of nutrients and bloom.  Then
as the plants began to take up those nutrients the algae would die back.

Sound logical?

Bill
