The last few times I've check the borate level using the test developed by @JoyfulNoise I've noticed that after adding enough R-0009 to get straw yellow, and then adding R-0010 it usually takes two drops to get the mixture to "baby blue", but the if it is left stirring for a few seconds (about...

Head up: The Lowes in Torrance (and possibly other LA area locations) has 31% MA for the first time I've ever seen. It's KemTek brand $15 for 2 gallons. There is a stack of the 14% KemTek product right along side, also $15 for 2 Gallons. The Lowes web site doesn't acknowledge that the 34%...

As I reported in this thread: Planning for RO treatment I had the Reverse Osmosis process run on my pool run back in late October. After re-balancing the chemistry the CH was 200-225 (Test the same day gave 225 two subsequent tests about a week later gave 200). Now 2 months later the CH is...

Greetings: I'm hoping this is the correct forum to post this: I have a correction (or possibly addition) to the Jandy Aquapure wiki page: Aquapure cycle time The wiki states that the Aquapure has a 3 hour cycle time -- 50% is 1.5 hour on, 1.5 hours off. Being suspicious that this was a...

I have our local reverse-osmosis provider scheduled for later this month. My goal with the process is to get the CH number down from it's current ~725 number to somewhere in the 250-300 range. With that plus adding borates I hope that I can allow the pH to stabilize in the 7.8-8.0 range and...

The Wiki article on Borates includes the statement: Is there a mechanism by which the borates degrade? Or is this statement just assuming some amount of water loss over the season due to backflushing, vacuum, or that strange phenomenon called rain that I hear happens in some places?

I've been generally happy with my Jandy Aqualink RS automation and the IQ-30 controls. However there have been enough times that I've been at the pool and realize that I need to go back inside and get my phone just to turn on the SPA. That plus the fact that you have to have a functioning...

Chemistry question for @JoyfulNoise : I have noticed that my FC takes a ~1ppm jump the day after adding acid to my SWG pool. I generally test once a day and then add any needed chemicals. The Pebbletec pool is now about 6 months old and always covered except for the 30-60 minutes per day when...

I have a new (installed in October) Jandy heater that is making a loud Howl or whine. The symptoms are very similar to the issue described in this posting: https://www.troublefreepool.com/threads/jandy-jxi-heater-whine.224775. The noise starts a few seconds after the burner lights. The burner...

My new pool came with the Jandy RS-4 controller and Aqualink IQ-30. The Aqualink works great, my only concern is that it completely dependent on working internet. Should my internet go down, the only control is the "Maintenance mode" on the RS-4. It is a bit disappointing that the IQ does...

Greetings: I am the owner of a brand new Pebbletek pool with SWG, and am now at the 2 month point since the pool was filled in mid October. The SWG was started up December 1 (almost 3 weeks ago). It is an outdoor pool, but equipped with an motorized cover that is close nearly all the time...

Greetings: I know this forum is mostly posts from folks with work underway but I thought I might share our nearly year long pool building adventure. Highlights of the timeline were: 10/25/20 - Signed the contract with pool builder 5/20/21 - Excavation begins 6/16/21 - Shotcrete 10/12/21 -...

Last weekend I started up the SWG on our brand new pool (Jandy FusionSoft 1400). Per the Jandy instructions I first checked the salinity readout on the system which was 1.3 g/L. So I calculated out and added 2 g/L of salt (100lb in a 6100 Gallon pool if anyone want's to check my math). Sure...

Greetings everyone: I've been reading this site for several months now as construction has on our new pool was under way, and now it's finally finished (just in time for cooler weather :(). The pool is small -- 6100 gallons, Pebbletek finish, Jandy SWG not yet online as we need to wait...
