i am getting ready to change from halides and actinic to led i have a 75 gallon fowlr tank and a 3 inch live sand bed tank is 6 years old no problems with chemistry. i may want to get into keeping corals so i need the proper led lighting. i saw some kessils at the fish store a350 i think on a tank i was impressed with that i would need 2 of them probabably a360w for my tank.i like the goose necks also.however i also like ecotech radions which ones do you prefer and why .thanks in advance
