I have had my tank for about 8 months now. It is a 40 breeder from petco and a 20 long for sump with a baffle kit from ebay. I have filter socks and a small gfo/carbon filter, and a CO2 scrubber on the inlet of the vertex skimmer. I have fiddle with this skimmer for months. i have set it and left alone for days skimming realy low in the neck to avoid an overflow of the cup. I will look at it before bed and not have 1/2 an inch of dark skimmate in the cup and wake up to it blowing bubbles out of the top. I do not know what i am doing wrong i have played with multiple different sump water heights and everything. Has anyone else run into this problem or have any ideas of what i am doing wrong.
