Ready to start this weekend

Except ATS, what equipment else I need to filter?

Nothing.

Because everyone around me tell me to get a protein separator at least, but I still insist on ATS only.
They weakened my confidence, so I came here to find it back;)

Thank you!

I do not have any SW tank with anything more then a scrubber nor do I plan to. My nutrient tests are always zero-ish and my dosing amounts are very predictable. The little algae break outs have stopped all together.
Are you going to have Coral??? If you are then you do not want a protein skimmer since it removes food for the corals. If its a fish only then a skimmer is just fine.

I do want to have corals with few fish. But excuse me what is the 'SW tank'?
My poor English~~:confused:

Salt Water

Thanks
