Add borates! I love what it does in terms of shimmer to the waterDirk is part of the reason I ended up with one of my favorite additions to my pool! After seeing his acid pump and the setup that Brian used I decided I had to have it.
My Jandy automation only allows 1 minute minimum run times - so I am running two 1 minute cycles to keep me in the 7.6-7.8 range - on average I need about 8-10oz every week of the 14% stuff so my automation runs twice a week. I guess it would be nice to dose for 20 seconds every day - but that isn't in the mix for me and my automation...
I could also further dilute my acid in half again and run it 4 times per week, but that seems like extra work.
I am also toying with finally adding borates to my pool - which may change the acid curve.
