If I may tag-along with a question for Tom (and forgive me if my paraphrasing is wrong): You recommend minimal water changes with non-CO2 so as to avoid algae-inducing spikes in CO2. Does the same caveat apply if using remineralized RO/DI for changes? I've often read that high CO2 levels in tap will deplete a DI resin rather quickly so my assumption has been that it's removing it. Or would water pick up enough just sitting so as to make it that much higher in CO2 than we'd find in a planted aquarium with no added gas?
