I am currently running a 8 bulb T5 with reefbright HO blue strip lights on either side. I am looking at swapping the T5 fixture. Tank is 210g 72X24X29. Have looked at the radion 30s but hard to justify $5k in lighting for my tank. Also looking at the neptune sky which seems more affordable figure i would need 3 of those. Looking for any suggestions you may have or incites on what you are using.
