I'm kind of updating my question from above or at least modifying it. I thought that I would be more specific in my equipment and parameters.
I have a 29 gal tank, bought used from a friend $20. It has been running now for around 4 months. Have 28#s LR, 20#s LS, 4 turbo

, skunk cleaner, and a red legged hermit crab. I had an Ocellaris clown but he's gone.

My parameters and equipment are such:
ammonia - 0
Nitrite - 0
Nitrate - < 10
pH - 8.3
Spec Grav - .025
Copper - 0
Temp - 79
Lighting -
2 T5 HO 10000k
2 450 nm actinics
2 Moon glow leDs
Powerhead - 400gph
The only thing else I want to stock it with are a pair of clowns and a sea anemone. I'm moving in a month

so I'm in no rush, don't plan on doing anything til I get the tank setup in new house. In fact, don't really plan on buying the anemone for at least another couple of months.
My questions are:
1 What other test kits do I need?
2 Do I need a protein skimmer, and if so which is a good HOB one? I heard the remora HOB is good as long as it has the Maxi Jet pump.
3 Which anemone should I get?
4 Which clowns should I get that would have the best chances of hosting above anemone?
5 Do I need more LR for better filtration?
6 Do I need another powerhead?
7 I have a HOB filter right now, but my LFS says that if I have enough LR and protein skimmer I don't need the HOB filter. How much more live rock would I need?
8 How difficult would it be to make a sump for the tank and how big would it have to be?
Thanks for any and all help
