Nuvo 30L chamber setup, intank basket

[burrito]

So i am just about done with my cycle and looking to get opinions on the most efficient setup of my chambers.  the nuvo 30 looks more or less like this below.

so starting from left to right. 

LEFT LEFT: intank filter floss holder w/floss

LEFT MIDDLE: ghost skimmer

MIDDLE: SICCI 1.5 return pump, 100w neo therm heater, ATO sensor

RIGHT MIDDLE: Reefkeeper PH and Temp prob

RIGHT RIGHT: intank media basket TOP: floss, chemipure blue, empty

 

i plan on adding marinepure balls since i'm only running about 15lbs of live rock in display.  

 

where should i put the marinepure balls? in the media chamber? set them under the LEFT LEFT filter floss holder?

 

anything i should add and where should the water level in the middle chamber be? i keep mine about 1.5 inches below the baffle walls of the first 2 chambers

 

i also have an IM wavelink in the display tank for some random flow/gyre

Left/left in a larger media bag, in case you need to take them out for maintenance or other reasons.

I keep my water level 1/4”- 3/8” over last baffle (middle/return chamber). YMMV
