No a Hob
is exactly as the name suggests, it hangs on the back of your tank. I am not a big fan of these but perhaps someone else can chime in with advice on how to use it/what to run in it. Without a sump you will need a skimmer for sure on that size tank so you will also need a HOB
style too. Try and get one rated for twice your tank volume if you can. This is one of the main benefits of a sump - it's a place to put all your equipment so you don't need to look at it on the display! You will end up with heaters, skimmer, hob
filter and a couple of powerheads and of course lighting!
That depends on what you want to keep, for fish only it doesn't really matter, for reef that's a different story and you can drop a lot of cash here. LEDs are recommended, don't do what I did, go cheap and first buy T8 (thinking I would only have fowler) then a couple of months later upgrade to 4x t5 HO
, then a few months after that upgrade to LED
. Wasted money!
