I have a red sea classic with a mag 5 that I use. It works but they need attention to their adjustments. I would not think a sea clone or a prizm could handle a 90 gal
I want to get a Urchin Pro for my 75 gal
. I'll sell you the Berlin w/ pump if your interested.
*180 gal Display, 100 gal basement sump, 33 gal refugium, 3x250 MH, 2x160 VHO actinics, zoos, some softies, LPS & lots of acros and other SPS.
*100 gal prop tank plumbed into main system w/ 2x96 PC lights and 1x150 MH,
