So here is what I came up with.
ATI bulbs Blue+ & Coral+=$40
A 30" fixture can only hold 24" bulbs that are 24W a piece to fit in that acrylic area.
Deep Blue Solarmaxho2 HO T5 or the Solarmax HO T5. You can do this with for $118.
So aside of taxes you are under $180. It is the best cheapest fixture out there that will get you started, the ability to hold coral life in the softies range no problem like zoanthids, frogspawn, hammers, pulsing xenias, torch, and green star polyps which people consider beginner corals. Basically corals you don't have to dose and spend money on PAR meters, APEX, and dosing pumps. What I call chest puffer corals. Pay out the wazoo to lesson your headache when you can use the KISS theory of "Keep it simple stupid" then you don't have to worry about headaches. I get where you are going with your tank. Go with it. It will work. A protein skimmer I will recommend if you don't have one already. If you have a sump. You would have to ask someone else. If you are looking for a HOB(Hang off the back) Reef Octopus HB1000 & 2000 are quality ones. Just don't buy a skimmer with a paddle wheel. It has to be a needle in the pump for the skimmer. Good luck my friend. Enjoy the hobby! Any questions just ask.
