I'm looking for the cheapest WORKING lights to grow corals

Any recommendations?

I would go with a 2-4 bulb t5ho,Cheap fixture on ebay would work just make sure you use ATI bulbs

 

[c.hill1100]

Would it be enough light for this setup

 

[DSP]

Oh yes more then enough.

Find a decent 4 bulb t5 fixture. It will definitely be plenty of light I used to run a 24 inch tek 4 bulb and had 200 par on sand bed. Definitely get ati bulbs.

I'm goin a little off topic but how can I do a filtration system without drilling or a sump?

Can I just have power heads and do frequent water changes?
