Ok so ive had my nuvo 10 up for about 4 years now. started off as a complete noob and over the years i feel like im fairly experienced in the hobby now. I had that piece of crap IM ghost protein skimmer for a couple years and took that out because it belongs in the trash, anyways i only have 1 clown in there and some snails, hermits and a lot of acropora. I ran GFO on and off for awhile but kept losing colors in SPS, and trying to maintain ULN phosphates in a 10 gallon is a joke so i just run filter pads, chemi pure elite in the media basket and carbon in the mini max media reactor. My nitrates have always read 0 "nyos test" and phosphates around .01-.06 "Hanna". I bought a reef glass skimmer thinking it would be perfect size for this tank which it is however i cannot get it to produce any foam/skimmate at all. Ive played with the air valve and the height and still no foam. my question is, is it possible my bio load is so light with only one fish i simply can't produce skimmate but enough phosphate from that to cause brown algae on the glass every day? just wanted to lower my glass cleaning maintenance but also don't want 0 phosphates as i will lose my acros. what do you guys think?
