Hort. Hybrids

if the acid is very strong, anything will dissolved... Remember "Alien"?

Inert usually means it doesn't contain excess salts and minerals that will leech out and will not react chemically especially for horticulture term.

I have used both perlite and pumice extensively with no ill effect for neps.

Not recommended to use even if you rinsed throughly to get rid of any trace of sea salts and minerals. Corals are mainly calcium carbonate which will be eventually dissolved in acidic media that most nep prefer. When that happend, the pH of the media will actually become higher (ph >7 = basic) and that's is not what most nep prefer.

However, there's always exception to the rules, neps like N. northiana, N. campanulata and other lithophytic neps where it originally grew on limestone substrate, coral chips "might be" a suitable replacement for limestone.

thank you for the 'might be' reminder and will take note about it.
