This was a sticky for a reason, I see (not that we randomly sticky things on here for no reason) As a result, that article... GOT BOOKMARKED. Thanks to whoever said in years past to explore the stickies first thing! I can easily see I have some work to do, however...
If it's true that aquatic plants produce about 5 times more oxygen than they use, and when my fish get to be ~12 inches (goldfish, very messy and oxygen users)... What I'm trying to spit out here is that my tank is not heavily planted. I have 1 two liter DIY co2. Not enough in a 55g, that much I know. However, I have an aerator: Rena-Air 200. I have seen beautifully planted goldfish tanks with an air stone and man, were his plants beautiful! He had fully grown fancies, but I can't remember if he did co2 or not. And my Rotala wallichi and sword plant are making a (slight) comeback since I started my co2. That added, what thinketh thee here in attendance about these questions: Because my tank is not heavily planted and under co2-ed, and this article says that an air stone drives out co2, do I remove it, or will my fish suffocate without it at night when plants also take in oxygen? Or will they be okay what with plants producing 5x more oxygen than they use? Should I put the aerator back in when they get ~12 inches? My plants don't pearl or anything, I give my wreck of a tank no ferts so yet another question is this: Is that five times more oxygen statistic less than 5x with my tank? Have we heard of the 5x stat here, or has my brain randomly remembered or made that up to mock me? :der:
Forgive me for a) asking questions that may be obvious beyond belief, b) a text wall of a post, and c) for my meaning being unclear. But nonetheless, I'll be looking here for answers after I get back from up north on Tuesday (We'll be swimming in lakes and fishing, so I might be taking a trophy weed bass home. Maybe I'll find some aquatic moss swimming. Anything that'll survive in the lakes up there should stand my coldwater. *Walks off dreaming of beautifully planted tank with pretty carp*)
My deepest thanks to you all!
