> **Pool 0 (BLUB-AQUA) — emissions paused pending Aquarius whitelist approval.** The pool is live and POL liquidity is deposited, but it is not on the Aquarius gauge whitelist, so it currently receives 0 AQUA emissions. Reward distribution resumes automatically once the Aquarius whitelist team approves the pair.
