So my TA was up to about 200 at one point this year. I have slowly dropped it by adding MA and then letting PH creep back up then add more MA. It is now down about 90 and am fine with that. But every time I add MA to the pool my pump pressure goes up one the next 24 hours to a point where it needs back washed. I haven't backwashed it just bump the pump and after a couple days of that the pressure stabilizes. Is this normal? Its not a big deal just wondering if this is normal.
