Depending on what you intend to keep at the end of the day. A good turnover rate will ensure water will go through the "cleaning process" faster. I suggest getting a Eheim 1262-1264 (3400-4500l/h) as your main return pump for your new 3ft tank for reliability and Jebao wp25 (8000l/h) x 2 for your internal tank circulation. That will give you a good turnover rate of >50x for most of the demanding corals. For my tank I ran 120x turnover rate.
My ios only have my life reef skimmer & a small bag of carbon for first compartment and 2nd compartment return pump to chiller back to tank. Thats all.....whatever the skimmer did not pick up, I will syphon it out during forthnightly water change.

I go bare bottom for almost a year till I notice not much detritus accumulation then I add in the shallow sand. Works well for me. The bare bottom allow me to keep my nutrients low through siphoning the detritus.
No need all the fanciful things, a good skimmer, rowaphos and weekly water change is all you need. Go very slow on your live stocks and feeding else nuisance algaes will be hard to deal with for a small volume tank.
