High range ph at 8.4!!!

How do I get this down and quick.

Natural PH levels are between 8.0 and 8.3 as long as it doesn't keep rising you should be good. 8.4 isn't bad.

That gave me a scare. I got two yellow tail damsels and one is going berserk.

You should be fine with that as said before, also, going forward, now that you have live things in your tank, big swings can be more detrimental than having numbers outside the norm. In this hobby, slow is better, don't start making huge changes without reading and asking questions.
