Hey all, new pool owner and luckily found TFP only a month in. Still going to pool school but so far I really like the philosophies and methods practiced here. The pool store has only gotten me for a bag of DE and a box of Balance 100. 
I bought a home with a 12 year old gunnite/plaster IG 18k gallon pool with builtin spa. 2 skimmers, 2 pool drains, 2 spa drains, Polaris 360, 2" pipes, jandy's, Purex 4000 DE filter, Purex whisperflo 2hp pump (220v), pool frog, 3" tab auto-chlorinator, and a BIG heater on a concrete pad. The filter is leaking out the backwash line so I'm going to make some changes.
Here's what I'm looking at doing:
-Pentair CCP420 filter (should I go 520?)
-Pentair IC40 SWG
-Delete Pool frog
-Pentair SVRS pump
Some concerns are that the IC40 is rated up to 40k gallons but I've seen people on here with under chlorination problems with the smaller IC20's. Stick with the 40 or drop down to the 20? The SVRS pump is impressive, expensive, and has some cool bells/whistles but at 3HP, is this thing overkill for my application? I know you can throttle it way down but what are your thoughts? Any suggestions or opinions are greatly appreciated!
