new tank update

[charlieweaver21]

So I started this tank only wanting to do fish and live rock only. Then quickly changed my mind. I have had the tank running for almost a month now.

75 gallon
75gallon sump ( filled with only about 50gallon)
20gallon refug (not set up yet)

In sump
2x 300 heaters set to 79
Coralife 125g protien skimmer
Mag 7 pump- running at 480gph at 5feet

In tank
90 pounds of caribsea live sand
60 pounds of live rock
Eshopps overflow box

Current Live stock
3 blue damsels
2 clown
4 peppermint shrimp
6 redleg hermits

Current water test
Ammo. 0
Nitrite. 0
Nitrate 0
Ph. 8.3
Phosphate .5
Calcium 460
Hardness 11

So only thing I plan on getting that I know I need is lighting and this has become very confusing. So I've decided I only wanna speed around 450 on lighting. And I'm thinking of 2 of these.

Let me know if these seem ok for doing corals or if you know of something better for around same price. Also any other recommendations would be greatly nice. Thanks
