Got the FC to 15 last night, this morning it is at 14. Still no change in visibility and no increase in filter pressure, flow is normal.
yes the biggest losses are during the daytime, I usually am able to keep up the FC in the mornings, but then being away from it from noon till 7-8 pm is when it really drops. Is it a good idea to bump it to say 18 FC at noon so it won't go too far down by 5 when it starts to shade?
i just tested after I topped the FC off at 8 a.m(45 mins.) and it is at 14 right now.
