Planning on stocking it with the following

Go with dry rock much cheaper and it will become live over time

if your gonna spend the money at petco get the 20g long for $20 and youll be much happier IMO, and i would go a little more overkill with the hob filter especially since i see you didnt list a skimmer which is fine with regular water changes, like almost double the gallon rating, if you go with a 20g long get a 40g rated filter, and go with dry rock and live sand, your gonna need a small piece of live rock to seed the dry rock, and for lighting you can go a little cheaper that marinleland if you plan on a fowlr tank, if your going for a future reef, dont skimp on the lighting, and for stock, so far so good, but your need snails as well, i would go with 3 nassarius, 3 turbos, and 3 ceriths snails.

You dont have to seed dry rock with live rock, you can do all dry, it will just take longer to cycle. If you want to introduce corraline algae then you will want at least one piece of live rock.
