I just started my first saltwater tank and i got a t5 Aqualight made by coralife. My tank is 29g tank and the lfs told me it would be ok. just needed to know what i could put in my tank with this light or if i should look at another light. Or maby haveing two of these???????????

One 18w true blue and one 18w 10,000k daytime?????????

I would look at getting another light. 36w over a 29 isnt very much light. You might could get away with some low light softies but definatly no LPS or SPS corals. As far as Fish it will be fine but thats not enough really for corals. If you just want softies and LPS then get a PC fixture somewhere in the 70-80w range. I personally have a 250w metal halide over my 30g.
