I have a 8foot long 300g tank, this is the equipment I am using;
I like vortech and maxspect gyre for water flow, I have a pair of Gyre 350's and a pair of mp40's on my 8foot 300g tank. Water flow is fantastic. Ecotech return pump (L1 still going strong 6 years into it)
Eshopps AF (fuge) sump with Eshopps skimmer. The fuge uses a sock type filter, I run a mesh bag there.
You will get 100 different answers on lights, so I will show you a couple of pictures. I just upgraded from ViparSpectra lights to the Reef-Labs Uno 2.0 pro. The Vipar are a decent starting light, they are affordable (cheap almost) but not a lot of adjustability on spectrum etc. Reefi lights have a really nice WIFI App you can tune the lights with!! A REALLY NICE APP!!! And the reefi lights are more wattage, and more led's, for about half the price of the "TOP END! Lights".
Finnex Titanium heaters are dependable and affordable, I would run a Redundant, just in case of failure.
