I run 2 Ai super sols over my red sea 34g. 2 is over-doing it, but i wanted a good spread. the timers are great and the sols are very intense/concentrated light. i am quite pleased with them.
the one thing that gets under my skin- some (sps) WILL NOT color up under them. i have a buddy that is running experiments with his (had 20+ years experience in the hobby). corals that are pink and green, red corals will not be a "deep" red, and very blue corals like hoeki won't develop their "deep" color either- i'm having issues keeping my hawkins a solid blue, my buddy's fire/ice echinata wont color up either.
that was a bit tangential and only my experience and his (sorry)
all in all though i am happy with the AI's, cant beat the extent to which you can customize the timers, they are solid lights- especially for the price. if you do decide to go the ai route, be sure to get as many modules as you foresee yourself needing in the future. the crees vary from batch to batch. (i went through this hell and it took 3 months and some serious luck to find a module made around the same time my original was- even now only the whites and royal blues match, but ill settle for that).
