I had a Whisper Diatomagic for several years before adding CO2 to the aquarium. Because of the strong surface agitation that is created by the return spout, I have been reluctant to use it assumming that it would rapidly deplete the CO2. I have never gone to the trouble to measure/estimate the CO2 concentration before and after using the Diatomagic. Have you noticed a difference in the CO2 after using it or do you just not worry about it?
What size of Vortex diatom filter are you using? I have the small model, D-1, for use in a 55 gal. and it works well. You should probably be using the larger model in a 80 gal. There is a large difference between the two in the surface area of the filters. When I started an aquarium with a Flourite substrate, I used the Vortex to remove the suspended particles that resulted from filling the aquarium...thought I had rinsed it well. It eventually did clog but it did a great job of removing the particles. Check the top of the filter mesh where it attaches to the base. Sometimes it may tear and may affect the efficiency of the filter. They recommend sealing around that point with aquarium silicon.
