I have a 220 on my 55gal. and it is great and outperforms the skimmers I have had so far (Aqua C Remora, Amiracle Quad 1, Seaclone 150, Red sea Prizm w/surface skimmer) as for there lights i would stay away and go with orbit because they are built like tanks, I dropped mine in my tank (oops!) and it was still running while under the water. plus i would have to say the bulbs were better as well, My tank looked alot better with orbit
I HATE MY AQUALIGHT!!!!
thats why i am going to get a PFO pro w/ 2 175 mh and 2 vhos as for the orbit it is still working like a horse at a local pet store.
