[APD] Vigorous aeration and NH3
I know this is off-topic, but there seem to be a number of chemistry
experts on this list. Since NH3 is a gas, wouldn't vigorous aeration
remove it? I do not know, however, if this would have a noticeable effect,
as I am under the impression that NH3 is the most soluble gas in
existence. Obviously for lower pH, where most ammonia is dissolved as
NH4+, this wouldn't have a lot of impact.
Now, a plant question:
In a plant tank not enriched with CO2 by any means except fish, what is
ratio of the CO2 produced by the fish to that used by the plants? In other
words, is a (unaerated) tank absorbing atmospheric CO2 for plant growth,
or losing it from fish loss (in an average plant tank). If it was losing
CO2, then would aeration pump more CO2 into the tank from the 0.03% in the
I am one day going to start a community tank with only a few plants and
fish, as my tank only holds ~ 80 litres (20 gallons?, it is 36"x12"x15")
which will not be my main tank. I have a one 30W Interpet Triton, a Fluval
3 Plus (I like them, even if they do take up a huge corner of the tank), a
few overpowered cheap heaters, and some plastic plants. I also have a 25W
substrate heating coil, obscurely, that I got of Ebay before I even had
the tank, but will not be using that for this tank. My aim is reasonable
health and survival, not spectacular growth, or in fact any growth.
Low-light plants for me. I want S. American fish (cardinals, otos and
maybe a bristlenose), but chances are the project will take 6 months just
for me to get the tank set up, so I am not in need of any advice just yet.
Oh no, I have just realised I have used the dreaded words in a post -
Please ignore as an obvious oversight.
