Midsize skimmer review and pics
I added the skimmer on 10/2; NO3, NH3, PO4 were all zero that day.
The skimmer was very easy to install. It was a matter of putting the pump on at the bottom, hooking up the air intake, and removing the 2 filter trays I had in the right overflow and just dropping the skimmer in. (My fuge pump is in the left overflow area.)
The skimmer comes with an acrylic bracket that attaches to the back glass with an acrylic screw to hold it in place. The bracket attachment to the tank seems very secure.
The instructions recommended setting the skimmer bubbles to the base of the skimmate collection cup; this wasn't difficult using a combination of twisting the handy black intake knob and the air intake.
I had thought that the skimmer was going to be taller- that the pump would rest on the bottom of the overflow area. This is not the case. The skimmer itself is held in the bracket by an acrylic screw (only one) that is very sensitive- the slightest bit of overtightening results in the screw popping out of place and the skimmer falls downward. This is frustrating because I have to very gently remove the skimmer cup to dump skimmate or the skimmer will fall downward out of the bracket.
The skimmer began producing a light tea-colored skimmate after about 3 days. Gradually, the skimmate has become darker and stinkier. The water clarity has improved and the algae growth- both green and brown- has decreased in rate.
Photos from this morning show 3 days of skimmate as I have been busy with work this week.

And I haven't taken the time to retest the water parameters- I'll do that today or tomorrow and probably do a small water change (5%).
Overall, I am very pleased with the skimmer and I would recommend it to other IM Nuvo 38 owners. It was easy to setup and began working rather quickly. It obviously is removing crud from the water. It fits perfectly in the overflow area. It is QUIET. I have had no issues with microbubbles. My only complaint is the rather loose manner in which the skimmer is secured to the bracket.
