20 gallon tall nano reef build

Hey all, old-new reefer here back at it after a long break. I started this 20 gallon on 12-9-17. She's (I think it's a she?) just starting to cycle.

My equipment is:
20 GAL high
Hydor koralia nano (425 gph)
Aquaclear 30 filter (150 gph)
*Tetra heater 100w heater (Gonna replace)

* beamswork light 60x .5 watt led light (52x 6,500k 8x actinic) (Gonna def. replace, its off a planted fresh I had set up)

20lbs live sand
17 lbs dry rock
8 lbs live rock (=25 lbs total, live and dry)

What do you guys think? I'm very open to suggestions and ideas, I've forgot a ton in the time I've been away from the hobby.

*My flow equals out to 28 times (the volume) per hour, I think that's enough?
*I like having the power filter so I can run media in it. Any suggestions? I was thinking purigen and or chemipure elite.
*still trying to decide on a light, def going with led, I'm just planning on doing easy corals (mushrooms, softs, and polyps) so I don't need anything too strong or fancy.
*I don't have a sump, but I was thinking of doing one of those diy hob refugiums out of a aquaclear 50, maybe?

I was thinking of stocking it with this:

*Fish
2x clown fish
1x tail spot blenny

*Inverts
Feather duster
Scarlet skunk cleaner shrimp

*Clean up crew
7x Trochus snails
7x Nerite snails
5x Blue legged hermit crabs

*And a ton of easy/intermediate corals.

Open to suggestions here too!
