One of the sets of tanks are non CO2.
Same effect.

These tanks have had Claphora growing in them as well as BBA for about
3 months now.
I've tried dosing 2x the rec initial amount daily for a week, 2 weeks
and have not seen any impact.

If you add Excel to a non CO2 tank, that dramatic selects for the
plants.......... same as adding CO2:-) and at lower light that is
typical with non CO2 tanks...that's enough to supply the growth rate
for the plants.

So you have a couple of issues happening in non CO2 tanks.

Thanks for the info! I love good control data.
