Hi,
The skimmer is noisy, hard to maintain (Fluval PS2) and eats coral's food.
I found a better solution - (UAS) Upflow Algae Scrubber. Your water will be crystal clear and maintenance is very easy.
You will need (upd. you don't need an airpump in AIO chamber area).
Innovative Marine AUQA Gadget Chaetomax 2-in-1 9W Refugium LED
1$ basked from the dollar store (just find any basket that will fit)
Plastic mesh screen (I rub it on asphalt to make it rough)
Airpump (I think is not necessary, but I use one for "Micro and nano bubble tank treatment" and for this scrubber too). I use Fluval Q2 (stay away from noisy Q1).
Airline tubing with many holes (I drill with 1/16 drill). Always use Check Valve and stay away from "Hagen Elite Check Valve".
Airline Gate Valve for air control
One Suction Cups (I use "Marina Black Thermometer Suction Cups")
I attach the mesh screen on each side of the basket (using tie wraps, but you can use reef safe glue).
Use a drill to make the hole in the airline tubing - if not, all the air will out from the biggest holes:
Scrubber test:
I put it in the middle chamber:

UAS in working (at night when light off):
Future upgrades:
I need to install this for better airline tubing:
Good luck!
