GFO reactor recommendation

[Texas Reefer]

I continue to have problems with cyanobacteria despite good maintenance. I could also have problems due to moving everything from a 120 to a 75 due to a Hurricane Harvey redo. But TBH, I had problems before.
Anyway, I'm looking at GFO reactors. Something that will work well on this 75, and then on my new 140. I also have a 20 frag tied to the system.
I've looked at the reactors on BRS, but they aren't very clear on what size tank, what water capacity, they are good for.
Any recommendations?

On the Bulk Reef Supply website home page there is a calculator link that uses your total water volume to help figure out how much media to run. Regular BRS GFO media for a 140 gallon system calculates 2.19 cups. High capacity GFO calculates a little over a cup for 140 gallons. From there you can look at the capacity of the reactor and see if it will fit the GFO you need to run.
