That bid looks much better. One inexpensive thing to consider adding is an inline tablet chlorinator, in addition to the SWG. They’re inexpensive (less than $100 for the part), and give you extra flexibility in case you want to use trichlor tablets. My pool just finished construction and was started up a few days ago. I have a tablet feeder immediately downstream of my SWG.
I know tablets are frowned up here, but it’s been convenient to have the tablet feeder because you aren’t supposed to add salt (or start the SWG) for 30 days with new plaster. Liquid chlorine is less convenient and hard to find right now, so the tablets have been great. The fact that they add CYA is even good if you’re going to transition to salt water, for which a higher CYA is recommended.
Plus, if your SWG ever has issues, you can use tablets temporarily. Something to consider as an inexpensive thing to add.
