need opinion on upgrade

[quallabear]

What should i upgrade first? My lighting from 2x175 Mh to 2x250 Mh or my skimmer from Red Sea Berlin to Precision Marine es100? tank is a 75 with 30 gallon sump.

I would say it depends on how good your water parameters are which one needs replced first. That and if you have any light hungry corals or not.

probably the skimmer first if it was me

I agree 2x175 is Plenty of light for a 75

Skimmer.

water parameters and corals are fine, just looking to spend some of my tax refund on upgrades to my tank.
