Fish breathe rapidly when CO2 is on and callibrated probe reads at least equal to or lower then 6.4. BBA growrh when pH less then 1 unit drop.
Awaiting arrival of surface skimmer as possible solution though other then 15% area frog bit plants no visible oil or other substance at surface.
setup as follows-

143 gallon waterbox aquarium.
Riggs co2 reactor.
Callibrated milwaukee ph controller.
1 pH drop- ambient pH 7.0, injection pH 6.0.
CO2 on 2 hours before lights and off an hour before lights at end of day.
Wave maker positioned toward surface creates mild wave effect.
2, 10 gallon whisper pumps with air stones each located at opposite ends of aquarium running 24/ 7.
Water temp 75 F. Kh 3, Gh 5.
3 AI Prime pendant lights set for low to medium light plants. Will provide light graph, settings shortly.
Crypt wendtii, phillipine java fern, anubia nana, and a stem plant.

Any suggestions? Thanks,

When you take a cup of aquarium water and let it outgas for 48 hours does it confirm the 1 ph drop calibration?

My understanding is that there is a bit more that goes into the 1ph drop equals 30ppm co2. Some folks need more ph drop then others to achieve the actual effect. Its possible you are one of those in the less column, also possible your fish are more sensitive then others?

Anyway other possible solutions is to adjust fertilizer and light intensity to affect a change in bba so you can lower your co2. If your fish are suffering at current levels my goal would be to lower those levels regardless, the rest is just figuring out what went wrong.

Agreed fish first. reluctant to turn down lights as plants grow tall and stringy. Here’s tank photo and light parameters.

Also have blue green algae. Plan to treat with ultra life.

Turns out fish have anchor worms which among other symptoms causes labored breathing.
Ordered Hikari Cryopro. Won't arrive until Monday meanwhile BBA growing while less then optimal CO2 levels. Any suggestions for how to minimize BBA growth while maintaining less then optimal CO2 in order to accommodate sick fish until treated and recovered? Reduce light intensity and duration but continue with less then optimal CO2? Turn off CO2 for 3 week treatment duration? Dont change anything and supplement with excel? Thanks,
