Neat observation about my new system and reactor

[Delphinus]

What surprises me is how much water turnover both you & I need (well, how much you "needed" and how much I "still need" because only one of us upgraded their tanks.. ) in the first place. I thought a larger reactor would need less water turnover and less CO2. I wonder if there's an optimal balance of "amount of media" to "amount of tank/coral load" and if it's too much one way or the other then you end up with settings that don't seem to match other designs?? On that note I actually have a question about reactors and media but I'm going to put that in another thread so as not to hijack this one..
