is this statement true?

"If you are not going to keep fish at all, maybe a skimmer or a canister filter can be skipped"

read this somewhere.

I'm lost on this one.

I suppose it's true as in that if you are not into fishkeeping, then why even bother with filters and skimmers.

sorry, sounds a bit misleading, but what they are saying is to just keep corals and inverts for a marine tank, without the fishes.

depends on waterchange frequency, feeding, type of corals etc.
as long as there's something alive in the tank, there's a chance that it may die n produce ammonia. inverts n uneaten food produce waste too.

corals like sps need much better water parameters than other corals so a protein skimmer would be most beneficial.

if u hv a pico/nano sized tank keeping only softies n maybe some lps, then with weekly waterchanges, protein skimmer n canister filter(for bio filtration) can be skipped.

Yes. Its true if there are refugium, plenium, DSB, Lots of LRs.
