Well, by the pH numbers, you've got lots of CO2... high enough your fish should be gasping at the surface. Anything over 30ppm is dangerous to fish and you're estimating 40-50... My guess is that you're really a tad lower than your estimate, probably closer to 30..

Regardless, you've got lots of CO2, and lots of light.

It is a little hard to tell from the pictures, but it looks like you've got some form of beard algae on the anubias... That's generally a tell-tale sign of too much light for the amount of CO2 present. Might want to cut the light back a bit.

Also, out of curiosity, why are you using PPS-pro on a high light, CO2 injected tank with large weekly water changes?

Most folks doing PPS-pro are either not high-light, or doing small water changes. It seems like your tank is almost ideal for EI rather than PPS-pro...
