The sump is your problem IMHO, you're gassing off your CO2...When injecting CO2 you really want to minimized your surface tension/agitation.

If you're looking for that AM 1000, they work excellent, I've run allot of reactors over the years and this one is by far the most effecient IME, I have a few of them, one is BNIB and can be had for half the price if you want it...I bought it for a new system build but then decided to try my hand at saltwater instead of another hitec planted system...
