Re: CO2 from tapwater
If you have confidence in the stability of your tapwater chlorine,
chloramine, and ammonia levels, you could make the input flow rate slow
enough to keep things safe.
Think of it as very frequent but small water changes. The trouble comes
if those levels fluctuate over the months and seasons and you haven't
accounted for them.
But personally, if I had easy access to a waterline and a sink from my
tank, I would try it. I'm certain that even if you just got the average
flow per month to match your monthly water changes, a constant flow would
be better for your plants and fish...an example:
Tank: 100 gallons
Water Changes: 25% every two weeks = 50 gallons in 28 days
Equivalent Flow: 1.8 gallons/day = 1.8% water change every day
I would feel safe doing a 1.8% water change daily with no water treatment.
To be extra sure, I could filter it with activated carbon, and I would be
tempted to start out that way, but I think it would remove some useful
ions and I would end up removing it.
