Yes! That looks like a nice size beginner tank. You'll have lots fish options but look at the tank cycling sticky at the top of the newbie forum. That's a very important first step before you get fish.
Also tell us what equipment you have. Lights? Filter? It looks like you have a biggish tank & a large sump? We'll help you!
It's a PowerHead 802. I've also got a Reef Octopus that I'm wanting to reuse as an added filter on the back along with the built in setup on the back using the pump from the other skimmer. Shouldn't be too complicated lol Don't know too much about the lights. I know they're bright as hell. And when on, there's blue and white lights.. read something about 10,000 K.
If you're not planning on a reef tank I would sell it. Freshwater tanks are much simpler, you don't need a protein skimmer and actinic bulb (the blue one... you need to replace that one if you're keeping it). Also a complete reef set up like you have is worth more as a f/w set up.
