Well par mapped my aquarium today with the seneye reef love this device. This was a test on a 75 gallon reef im trying to build up. it has 2 of the 1st gen reefbreeder lights about 7 years old. Both channels are maxed out. Ive been reefing for about 15 years and ready to make this a full reef. I started those 2 acanes as one eye frags 12 years ago in a hex tank with a fluval 304 under a metal halide. then a black box up to last year when i got this reef tank.
