Here is a progress report.

I have left the lights the same on the 75 gallon tank but have stopped the co2 and nutrients. With the soil substrate and fish load I think I will try this tank ala Walstad.

My 125 gallon tank was undergoing even more serious algae problems. I had previously adjusted the light heights on this tank so the intensity at the bottom was the same as the 75 gallon tank. So it was really a lo light tank also.

What I have done on the 125 gallon tank is to radically lower the lights (2xMH 175W + 96W PC). I think it can be considered a hi light tank now. I am continuing the co2, but for the time being I've reduced the nutrients to 5 ppm no3, .2 ppm Fe, .2 ppm po4 twice per week. I've also cleaned up the bottom and bleached a lot of the plants.

Here is a comparison of the light intensities now:
