yes, unless you research a new acid spell.

Heighten Spell + Acid Splash lets you cover any level you reach. (unfortunately you're basically wasting that spell slot...but your Reserve Feat is stronger than the actual spell that's fueling it, so you won't be tempted to run dry like the classic Fireball-powered-Fiery Burst! ^_^ )

Energy Substitution: Acid could work as well, with Scorching Ray or something.
