Prepping for new tank

[Serpantkeeper]

So here it goes, I think I’ve got the wife convinced to upgrade to a bigger tank and I’m compiling a list of “must haves” for this new tank. So I’m looking for suggestions on what everyone would have for their must haves for equipment and their reasons as to why. So far my thought for water movement is a pair of mp40s. I’m just going to run an eshoppes dosing pump as I’ve already got that. And wel that’s about where my list runs dry. Show what’s everyone’s must haves for........

Water movement
Lighting
Controllers/monitors
ATO
Reactors

This build will be for a 100 to 120 gallon set up
