Losing 3 ppm of chlorine a day

I actually have a 1 HP Hayward 2-speed Super Pump. I just updated it. The sand filter is a Hayward pro series high rate S244T. I was running it on low but for some reason, the flow didn't keep up and it ended up throwing air and the water sounded like it was trickling through the pipe leading into the pump. Soooo not wanting to burn up my "new last yr" pump, I just run it on high, 24/7 right now. Not sure what is going on there but I figured I would tackle one problem at a time.
Second day trying to keep it at shock, but it seems to burn off 3-4 ppm every 2 hrs. and I'm not always home. Maybe I should take it higher??? Should I add DE to the filter?
Our temps have been around 85 (30 for you, saw you were in the UK)

Thx for all your help!

Ok I see, well I agree to tackling one item at a time, it sounds like you maybe pulling air in on the low setting from somewhere but without a flow gauge test it's difficult to say. On my pool the water sounds like it's trickling to but it's at the flow I have selected to give the turnover rate I want. I agree that feels unnerving when you first change over from a pump wasting energy but the savings are tremendous when you get it setup and the filtration improves. Have to get someone to flow test it or buy a flow gauge as low settings on pumps don't give the same pressure rises as big oversized pumps do.

How is the chlorine figure doing?

Pretty sure I have it beat. FC reagent finally came and there is no FC. Lost about 1ppm from last night till 2 pm today. It's sunny and in the 80s/30s. Been running the pump on low and haven't had the air problem so all's good

Thanks again for your help!!

Result! glad to hear it's cleared up and pump running on low is a major plus.
