There are also some excellent calculators out there that will tell you how much of Component "x" to add to get to parameter "Y".
This is an especially useful one.
If your pump has some sort of pulse, crest, or randomization, try to have that enabled at some point in the day if it isn't. Most corals don't tend to like linear flow in one constant direction and prefer variation. I can't quite tell if that's a Jebao or an Ai Nero 3, but either way, just change one thing at a time first. Sometimes messing with multiple things to make one coral happy can cause you more problems, lol. I agree with trying just different placement first and leaving it alone for a few days. Good luck!
