    Hey everyone. I'm a newbie to saltwater tanks. I wanna keep a pair of clownfish. That's it for now. Nothing else till i get some experience.

    1) are live rocks and/or live sand really necessary in a SW tank? I'm kinda planning on going with a BB with or without live rock, depending on what you guys say.

    2) it'll be a 30-40 gallon tank. It might sound silly but i could i not use an internal filter (which does 800 gallons per hour) as it would work as a wave maker as well as do mechanical filtration? Or do i really have to go for a HOB filter? Or what else could i do?
    P.s : don't wanna go for a sump or a canister filter.

    Thanks :)

    P.p.s : I'm kinda leaning towards going with LR as it might help with biological filtration. No ?

    from what I have read it is the primary biological filtration of a saltwater tank so they are absolutely needed. However, I don't have saltwater just have done a lot of research so I would wait for someone else's exper opinion :)

    You can do fish only...but what kind of internal filter is this? There are some tanks that actually have some sort of internal filters set up on them from what I understand.

    Umm it's an internal filter i am using in one of my freshwater tanks . It's not a built-in filter
