My first 75g! What am I missing?

tank looks great! are you planning on having just endlers in there? looks perfect for some discus.

are they not extremely hard to keep? Does it need CO2?

Co2 is good for any planted tank. If you don't have it in there I would recommend doing some DIY or even pressurized if you have the money.
I think the tank looks very nice the way it is, doesn't really look like anything is missing.

As far as the discuss, with anything, just do your research and you shouldn't have any troubles.

260 watts on a 75 gallon? I would get on the CO2 ASAP. Once algae starts to take hold, you're going to be fighting it for a looooong time. Speaking here from personal experience.

ALGAE j/k it will come on its own

You might need some birth control in that tank. 30 endlers will be making a sexytime soon. Then you will have 150, then 250, etc.

Agreed

That much light, if it's all on for 10hrs/day or more, is gonna grow you some algae real soon! I have a 46G w/ about 2x92W, and I've had to only one run light at a time and break up the daily light cycle just to get my algae under control. I've still got a lot of algae though, and it's because I'm only running DIY CO2 right now, not a pressurized CO2 setup that could pump CO2 into my tank much faster than what I've got going right now.

Heavy light like this makes the fish happy and looks great, but IME, it means getting more technical with your chemical dosing and CO2 equipment to keep the algae under control.

For algae a simple thing to do would be to try to keep your nitrates up somewhat, that will reduce the amount of algae a little.

What about this set-up. The local fish store has this in stock for the same prices.
