    I have two options that i want to run passed the gurus.

    1) 2 x 24W T5 unit - R600.

    2) 4 x 24W T5 unit, with moonlight LED's and built in fan. - R1350.

    Its for my tank which is 600x300x300 (50L).

    I dont mind spending extra and going for the extra T5's ONLY IF it will benefit my corals in the end? or would the smaller unit be more than enough?

    Can you have too much light? How will the big unit affect my evaporation?

    I guess one of those Chinese made units again. Firstkly the ballast are crap and than the bulbs that come with it are useless. It will cost you around R180 to replace with a dual ballast and maybe around R200 for Giesemann bulbs. Maybe better to diy your own one.

    If you go the DIY route you are looking(roughly) at:

    Option 1 = R440-00
    Option 2 = R950-00

    O and remember option 2 with the fans will be useless if your tank hood is closed at the top as the fans will then be useless.(if you are going with the light unit and not DIY)

    Its a reeftek unit as far as i know. Its not quality but for a tank my size its impractical for me to spend upward of R2500 on lights.

    I would say the second option would be the best, you can never have enough light for a marine tank. It's a expensive unit for what you want, I would go the DIY route like previously stated. Evaporation will be more with increased light, but evaporation is good for a tank because it causes constant change of water, giving fresh water from you for the tank.

    thanks @Annoying. Seems like a good place to start, and when the bulbs go i can always replace with better ones.

    Geisman bulbs are very high quality bulbs, just check the light spectrum that you want and bobs your uncle. With the four t5 you will be able to keep a lot of corals. Most of the Lps, softies and maybe in the higher parts of the tank some sps, with good flow that is.

    reeftek is pretty decent quality. Go for the 4 t5's and when those globes are old you can always replace them. That unit is cheap hey. Normally they retail for around R2300

    I agree...

    The reeftek stuff is definitely good enough quality. I'd just change the tubes to Geissman tubes. Then if anything happens to one of the tubes, you have a temp backup!

    Go the 4x bulb route..
    Then replace them with Giessman bulbs when its time to replace them.

    Thats what im doing on my 600
