120 Gallon Mixed Reef Build Help

I have a friend who's starting a new 120 Gallon tank, here's a list of the equipment chosen for the build. I want to hear everyone's opinions and suggestions on all the equipment below for a 120g build.

ADHI 30 Refugium Sump

Reef Octopus Diablo XS-225 Protein Skimmer

1 Vortech MP40 for now

2 Ecotech Radion Gen2

Tunze Osmolator Auto Top Off

2 phosban 150 reactors for Carbon & GFO

JBJ True Temp 500 Watt Heater

Please all input would greatly be appreciated. Or if there's anything we can get that's better.

 

Danner Mag Drive 1200 gph for return

 

Tank Dimensions are 48x24x24

 

I would go with 2 x 400 watt heaters rather than 1 x 500.....reason is that if one goes bad, you have a back up

Hows the craftsmanship, worth the buy?

 

just curious what about the jager heaters there supose to be much more effiecient

 

I have a Jager in all 4 of my tanks

 

I would only do this with a controller. Reason being is it is not uncommon for a heater to fail while on, and can cook a tank. With two heaters, now you have double the opportunity for this failure. At least with a controller you can easily shut them off on high temp.

 

Thanks for the tip, ill consider adding a second down the line.
