I have a tank that contains a black moor.. I just checked the ph level and it's quite high.. I'm going to use api ph down.. is it ok to use it when fish are in the tank?
 
I wouldn’t recommend it. Stability is way more important than a particular number.

Those products just lead to unstable ph conditions and so more harm than good.

Add peat moss or driftwood if you want to lower it more slowly and keep things more stable at a lower ph.
