Clownfish breathing heavy.

Phosphate will affect corals, but really doesn’t matter to fish that much. I doubt that’s the issue unless there was a major swing.
Using RO water is the best way to reduce phosphate.

Ok, so i think my clown might just be acting weird, he might also be very old. I will test the rest of my parameters when i get tests in the mail. Thanks.
