ok so i am in the works of upping my frag tank from the 5.5g (16x8x10 tall) to a 7.5g (24x12x6 tall) tank and i am having a debate with myself on which lighting system to choose for it. i currently have LEDS over the 5.5g tank.

The 5.5g tank with leds is nice for temperature control and keeping things steady but there are some frags i just can't keep under the LEDS, they either do not grow good or stay closed for some reason. on the other hand my main tank is t5's and it seems the ones that do not grow will grow in my main tank so i have to keep a frag rack in my main tank to cope with this issue.

so the debate is on the new tank do i go with LEDS, just more of them. Probably 12 or maybe 18 LEDS spread across the area equally for optimum lighting or do i go with a 2 bulb 24" t5 fixture and just do 2 blue + bulbs?

the t5's i know for sure will grow everything and with 2 blue + bulbs everything will look good but i have a yearly cost involved with the lights but i have a harder problem controlling heat with it, more so than LEDS at least.

Any input on what you think i should do would be great!
