I had a 40 gallon tank that started over a year ago. I’ve had my RSM 650 for about 10 months now that I bought used. It’s the old T5 setup and I haven’t changed the bulbs yet because I haven’t had any corals in that tank and the former owner claimed they weren’t old. Getting to my point, I have 4 bulbs on each wing for a total of 8 and another one in the middle I believe. Does anyone have a recommendation for brand and I don’t know what colors I should use. I lost a candy cane and a Star Polyp in my old tank and my frog spawn started great but then stalled and never got bigger. I believe that tanks problem was too much flow. I had an led light on it which may also had been turned up too much and they may have been lost from user inexperienced. Also had some zoas that barely grew that I got from reefapalooza last year in Orlando. I bought this weekend another star Polyp and candy cane as well as a hammer and a pair of mushrooms. They are in the RSM but I don’t want to risk using bulbs I have no real idea their age. Any tips and help would be greatly appreciated.
