tunze chaeto reactor

The instructions for my Tunze chaeto reactor (large version) say: Two questions: I don't really understand how the reactor can keep the nutrients stable, if I get rid of 90% of the cheato. Should I really toss about 90% of the cheato when I harvest? I measured out 390 grams and it's not really...

I’m considering a tunze chaeto reactor but I’m wondering: Can I remove the blackout film around the reactor to add more lights and remove more nutrients. I plan on adding some sun corals and feed heavy. thanks!
