bamburgb Posted March 16, 2020 Share Posted March 16, 2020 Right now im running 2 180w LEDs over my 180 gallon reef and am thinking about adding a 3rd (i have one i have always kept as a backup), in addition to that I am also debating on adding T5's but am unsure if it is needed or would be a good idea. I currently have a little of everything in the tank: LPS, SPS, Zoas, Softies and fish. I am debating on adding 4- 4' T5's but not sure if thats over kill for additional lighting or if thats a good amount. Quote Link to comment Share on other sites More sharing options...
bamburgb Posted March 16, 2020 Author Share Posted March 16, 2020 Also those who run T5's do you use a dimmer or do you have them at 100% all the time? Quote Link to comment Share on other sites More sharing options...
Gumby Posted March 16, 2020 Share Posted March 16, 2020 Unless you have alot of sps you can get away with 2 led but 3 would be better. I can get away with 2 foot between them but have to put low light Lps in the gap. My aquarium is 8'x 3'x 2'. I have 4 radion gen 4 pro's and 8 T5 bulbs. I am going to need more led's fairly soon with my tank starting to become Sps dominant to fill in the 2 foot gaps. If I could afford it. 1 Quote Link to comment Share on other sites More sharing options...

I was gonna be updating my LED's but due to the cost Im just looking at maybe adding my spare in and then adding T5's. Right now i only have a few SPS but am planning on getting more soonish. 1 Quote Link to comment Share on other sites More sharing options...
xxkenny90xx Posted March 16, 2020 Share Posted March 16, 2020 Are they just the black box type of leds? If yes then I'd say 3 of those would be perfect for your 180g 1 Quote Link to comment Share on other sites More sharing options...
