I believe my pool is about 35,000 gal. Initially the online pool calculator said I had 38,000, but I figure with the flat shallow end and the angles of the deep end its about 35K. At lease when I use pool math my changes in FC are closer to what it says they should be using the 35K value. I have a Master Temp 400K LP heater. How do I calculate how long it will take and how much LP it will burn for each degree in temp increase? Also, my CYA is 30. I have an automatic cover so the pool is covered unless we are using it. Is 30 alright or should I raise it?
