Anemone Tank - Couple questions

[Dos Ocho]

Hello all. I'm toying with the idea of setting up a tank for anemones and have a couple questions for you experienced folks out there. I successfully keep Rock Flower nems and 1 mini carpet nem in a current tank of mine. I want to venture into some of the bigger nems, but cannot put them in either of my two tanks, so thinking of starting a 3rd. Plus i have a 20 gallon sump collecting dust in a closet, so that is my justification!

Here is my idea. I'm really into the look of a shallow frag tank and think the Deep Blue 45 wide tank would be perfect for my plan and location. It is 36" wide, 24" long, and 12" tall. If i went forward with this, the livestock would be inverts only (crabs and shrimp). I would like to get some Florida Live Rock so whatever critters come in with that. Macroalgae heavy because i love the stuff. No fish. (I'm a weirdo and love reef tanks but not into fish that much. Strange, I know....)

I've been researching which nems to go with and i think Condy Anemones would be perfect for my goals with this tank. Would look at having 3 - 4 max in the tank.

So here are my 2 initial questions. Lighting. My budget for lighting would be $400 - $500.
My first thought was a 8 2ft T5 setup on chains to raise and lower as needed. Would be low initial cost, but would have to budget for yearly bulb replacement.
Also looking at 2 AI Primes. My thoughts here are two smaller LEDs providing better tank coverage, but would the light intensity be enough for the nems? High initial cost, but no ongoing maintenance costs.
Any advice on lighting is appreciated.

Next question is flow. My research tells me Condy's don't need intense flow, and i'd like to just use the return pump to provide flow for the tank. What is everyone's thoughts on this return line attachment?

The demo video is intriguing and not having a wavemaker would eliminate the possibility of a chopped up nem crashing the tank and would significantly reduce setup costs. My plan would be to split the return into two lock lines. One with a standard flare nozzle close to the surface for gas exchange and to minimze water siphoning back into the sump when the pump is off. The other lock line would have the random flow attachment deeper in the tank providing the current.

Any advice is welcome.

1. If you're really going to just do some Condy's you could easily get away with either lighting source. Condys are one of the least light requirement nems available to keep. Sadly they're also the least colorful and generally won't host anything. That said, if that's your jam, do you.

2. I actually have those exact things on my tank and they are solid. Now if your return flow is really low, they're not going to do a ton for you, but if you have some strong return flow, you could probably get by with them.

Thanks for the reply! I was thinking of using a Reef Octopus Various 4 so that should provide plenty of flow.
