New prop system

[RRodrigues]

Hi all,

I'm planning my first prop system for hard and soft corals and want all advice I can get:

Dimensions: 79 x 27 x 16 (148 gal) - 16" is too much for height?

Filtration: live rock (lbs?) and DIY skimmer in sump, bare-bottom?

Lighting: 3 x 150W hqi (10k or 14k?) + T8 actinic + natural light, the tank is going to be in front of a window (North, no direct sun);

Auto Top-off with RO/DI and Nielsen reactor;

Water circulation 15x tank volume;

I'm going to use natural seawater;

In the future I'm planning to use a Calcium reactor;

I'm not planning to use any chemical product to increase coral growth;

I'm planning to do frequent water changes for nutrient recycling and pristine water conditions.

Any suggestion will be appreciated.

Thank you,
Ricardo Rodrigues
