I agree 100%, best left alone give it time to adjust mine is doing very well after a full year it has split 2 times now and parameters are not perfect looking very healthy though..Ever BTA I’ve ever added hides for 2-3 days.
don’t mess with him just let him be.
Don’t do anything to you water as what he’s trying to do is adjust.
If you make changes you’re going to bother him.
As long as before you added him you’re pretty sure your parameters where in check he should be okay.
give him 2-3 days.
