Can you actually run a wet dry at a higher co2 ppm than with a canister?
It seems that some of you are claiming that? I didn't think that was possible but you learn something new everyday.
no and yes.. you can run a cannister just as high
but on a tank full of fish and shrimp, having the extra oxygen provided by a wet/dry is very beneficial and they will much appreciate it
Tom has tested and see's a 2-3 ppm increase over other types of filtration in terms of oxygen before plants start producing.
my fish agree with this conclusion. my tank has never looked healthier since switching to a wet/dry and i wont switch back. even my shrimp tank has one now.
wet/dry's are not nitrate factories. cannisters are because most people fill them with floss type materials that hold debris. my mechanical pad gets changed weekly and its about 1/4 an inch thick and 10 inches by 6 inches. its not a lot.
the rest of my media is bio bale which is slick and doesn't hold tons of debris
my tank as of this morning.. other pictures are in the journal. even my yellow drop checker a few pages back. its more of a reference point than anything, just to know my co2 is on and working
