since your tank is 50 gallon i think your best to go with the pc w/halides you will be able to have whatever you want in there.

you can go with the t5 or the halides but if you get the t5 switch the bulbs to 10k as it would be better(i think).

IMO halides are going to be out of the picture as soon as LEDs really hit strong, which they are starting to, and I have confidence they will prove themselves to be the lighting of choice over time. For now I would think T5HO - less heat. But I've never used halides. So much mixing up you can do with 4 T5s. I would shy away from PCs myself, T5HO is better (IMO)

It is holding the front and back glass from bowing and stressing the seals. You can cut it out, if you like water on your floor.

The other option is to silicone a sheet of glass in the same location bonded to the front and back of the tank, but I doubt that is the end result you wanted (no obstruction)

Forget the anemone and light your tank for corals. Anemones live so long in the wild that we don't know their lifespan. In a home aquarium most die within the first year.

Clown fish do NOT need an anemone to host. My wild caught true percula are now hosting a frogspawn. Clown fish will host almost anything given time.

Given the above, I would go with the 4 bulb T5 light setup for now. Make sure the fixture has individual, highly polished, parabolic reflectors for each bulb. If it doesn't, save your money for a better fixture. I also agree on using 10k bulbs in combination with others. There's a whole series of new blue bulbs out for T5. A 10k/ 03 Actinic is a classic combination. 6700k is on the yellow side.

what are the dimensions of this tank? 36x 20 x 20? it's important to know how deep the tank is top to bottom, and how long it is. most halide fixtures that come in 36" have only 1 halide lamp. i would not suggest this for your tank. the outer edges will be barely lit.
i probably wouldn't go with 4 x 39 watt t-5 ho either. i would want 6 lamps. look for a 6 x 39 watt t-5 HO, that is individually reflected. you don't want a single piece of flat aluminum behind all the bulbs...you definitely want it to contour around each individual lamp. this is very important. it increases the potency of the lamps tremendously.

also, watch out for those ebay no-name fixtures. many of them are not UL listed and have poor construction. in all cases you'll need to put better bulbs in them and in many cases, you'll need to change the ballasts. they can and have started house fires as well.


yeah, that plastic in the center is structural. i wouldn't remove it.

if you are price shopping, you are better served looking for a used quality fixture on the forums, and craigslist...and don't even think about LEDs! they are still, quite expensive.
