Now that's the truth.
I don't "defend" sumps, but would argue the claims that they are "not good for planted tanks". As for CO2 offgassing, my 5lb cylinder is approaching 3 months use in a 100 gallon display tank that uses a sump, and that's running CO2 12 hours per day. The sump is also an EXCELLENT mechanical filter. I use only a 100 micron filter sock on the overflow and it removes 4 or 5 times the gunk that the XP3 running in the same tank collects.
