Salt Water Pool Jandy System

[calisoldier]

I have a Jandy Salt Walt system with a spa. I'm wondering if there is a DIY maintenance guides and schedule I can follow. It seems relatively easy, but I don't want to miss anything. I took a rough estimate to find how many gallons my pool is, it's difficult because it's not perfectly square and the spa takes some space, but I'm guessing it doesn't have to be super exact.

Here the components:
AquaPure Salt Cell (PLC1400)
Jandy Stealth VSS
VSPlusHP (Booster)
JXi Pool and Spa Heater

One other things, there is a breather tube for the booster pump. After the pump is turned off, some water expels out of that tube. Is there supposed to be a specific height that tube is supposed to be so it doesn't do that? Or is there a setting/adjustment that can be done elsewhere to prevent that?

Your guess on the size of your pool can be off a couple thousand gallons and it won't make much difference.

The important factor is making sure that your FC and CYA are in the right relationship per this chart... FC/CYA Levels

Also see this video.. FC/CYA Levels

If you can do that, the rest is easy.

Thanks,

Hi Jim,

Just tested CYA with my Taylor kit, but it appears to be low/nonexistent or my fluid is expired. My pool guy just came yesterday so I'm assuming he didn't/doesn't add enough acid.

Just so that we are both on the same page. When most people talk about adding acid to their pools, they are talking about adding Muriatic Acid (MA) to reduce their pH. Most people don't call CYA an acid, even though it is.. Usually, CYA is called CYA or Stabilizer.

Most pool guys don't even check CYA. He may not even realize that you have a saltwater pool. Does he throw in bags of pool store shock on a weekly basis? If so, he has no clue how to treat a saltwater pool.

CYA protects the FC (Chlorine) generated by your SWCG from being quickly consumed by the sun. If you look at the saltwater tab in the FC to CYA chart above, you will notice that we recommend a CYA of 60 to 80 for saltwater pools.

If you want to get your SWCG working right, you need to do the following.

1. Get your CYA up to 50 (Can increase to 70 later)
2. Make sure your salt level is correct for your cell (most likely 3600 ppm or so)
3. Determine the amount of FC your pool uses each day and then adjust your cell's output and pump run time to make that same amount of chlorine. (Basically, replace what is used each day)
4. Maintain the proper FC for your CYA level.

Sounds like a lot, but it is not and once you get it set up, you just have to keep an eye on it.

Thanks,

Yes, I realized Stabilizer is totally different than MA. Based off that, I believe there isn't any CYA in the pool presently. Looks like I'll be busy buying Sanitizer, Taylor CYA agent, and Taylor's K-1766 Salt Test Kit. However, I think my Salt System measures salt current level, have to check that.

My current pool Chlorine production is set 90%, spa is set to 5%, and the salt level is at 3500ppm (3.5). The manual says the salt level should be between 3.0 and 3.5. I'm assuming my Chlorine production levels will need to be dialed down after adding sanitizer, maximizing Chlorine effectiveness. Does that sound right?

What about Mauriac Acid? The pool guy just pours that in normally to keep Ph down.
