Just got new AI Sol Blue with controller! I'm new but it seems light this light with controller can do anything. My PC's just weren't doing it for me. I wanted to be able to keep anything without light being the deciding factor. I also love love the shimmer it puts off and it's SILENT! Got a great deal at Aquatica in Tinley Park and I couldn't be happier. Cycle is already started and showing nitrites already. Just love this light! They said I will be good with one and it seems like more than enough coverage and I saved a few bucks by building my own hanging rig. This is with everything on 100% because I hadn't programmed the controller yet. Man led's for with controller for less than 500....I can't believe it. I almost spent 1900 on a acan the day before. Glad I waited. Thanks Mario!
