I know I am repeating myself, but I am enjoying the irony of running three $12 filters with a $500 automation system! I am currently waiting for replies on the Apex forum for how to program a fake control for my Fluval 3.0 lights, so I can track temp and pH vs lights and filters.
I've already tested one thing. I had my MF-10s stirring air in by running at the waterline. When I pushed them down about six cm, I saw my pH drop by from about 8.5 average to about 8.1.
It used to have inverse pH correlation with my temp after I removed my heater, but now they seem more in-sync with each other.
I don't want to draw any conclusions, but it is fun to combine my IT skills with my aquarium hobby.
BTW, if I ever decide to add CO2, can my realtime pH monitoring save me from running a drop checker? I can automate a solenoid based on pH.
I will add that I think these filters are the most economical utility powerhead filters on the market. They look like Cylon kitchen equipment, but they have a nice foam filter in a plastic box you can pull out, even while the filter is running and suctioned to the glass. They come with some carbon in a cut cylindrical slot in the foam, capped with a fitted foam cylinder. I'll run as-is in my top-off bucket, but for in-tank, I dump the carbon, push the cap in, and run the full foam edge at the bottom, to keep babies out.
Basically, I value it as a baby-proof powerhead which happens to have a nice block of foam!
