i left my wet/dry open for the first time last week during medication. and i gotta say, i didnt have to adjust my co2 at all. i had never not sealed it.
my 75 gallon recieves tons of light, i would have quickly noticed a problem if co2 had gone awry.
most wet drys i believe waste co2 due to too high of drain pipe flow for sizing. i cut my co2 consumption in half mearly by upgrading my drain size.
smaller IE most commercial overrated drains suck in lots of air and cuase need for silencing methods such as durso, herbie, bean animal, maggie muffler.
picking larger drains allows air to equilize pressure in the drain tube. my 75 has a 1.5 inch drain. supposedly itll hanle 1600 gph, ive dumped tons of water, and it does, but its noisey and gurgles and looks unsafe
750 gph is its max gravity fed drain rating, and i gotta tell you, its quiet for an overflow box
