My reef tank stand finally arrived, and moved my tank to the stand just now

But not sure was the electric cable thingy correct or not, if any suggestion for me to improve, I'd like to hear

(oh btw, I planned to make sump in future, the sump size is roughly around 50×20×40)

Sometimes it's fun and enjoying to see your corals and fish thrive

Setup rating?

How much would u guys give in a total of 10?

(That one coral on the highest is birdnest sps coral)

(Btw, any suggestion to improve my tank based on the parameters and equipment I updated today?)

Epik parameter

No3 = 50

No2 = 1

Cl² = 0

KH = 7~9

Ph = 8.4

Any suggestion to improve my setup based on my coral?
