CYA has no effect on chlorine generation. CYA does buffer chlorine harshness. I would run your CYA at 20-30.So here are my questions. On the wiki here is suggests 60ppm CYA for swg. But I don't need it for UV at all, is this going to be critical for the chlorine generation? I do understand that the CYA is a buffer and sort of "reservoir" for FC.
No, Salt is salt.Is the type of salt going to limit FC production?
Are there any specs anywhere of what your Salton SWG chlorine output should be? 8 hour runtime may not be enough. Why not run it for 24 hours or more and see what FC you get?My water is 2 weeks old and I've shocked it once as noted above, tested it many times each day as I'm learning all this. I cannot imagine the saltron is not working as it's bubbling up like it should. I've wondered if I have some growth that's too much for the swg but when I was adding dichlor to get the CYA up it was the same amount every day pretty much.
After reading this forum I am very hesitant to get in anyone else’s water- tfp has made me a water snob lol I have come to realize most owners have no clue what’s going on in there pool or spa & don’t care to know! They can swim in it but i ain’t gonna You’ll sort it out & get a “feel” for the maintenance of it & be more comfortable in time. The important thing is that u are asking all the right ?’s & everyone here will help u along the way! Happy Hot tubbing!Thanks for the reply. I thought about a timer actually. Turns out it's been more confusing that I thought it would be. I am currently running it for 16 hours in a 425 gallon tub. I've got a lot of questions I'm going to have to start another thread for. I guess if I didn't test so much I would be blissfully ignorant lol. Thanks again for sharing.
pH is the only factor for corrosion to metal. CSI is the only item of concern for corrosion to stone/tile/gunite, or buildup of precipitate. All the other factors either feed into the adjustments for pH and CSI or have some other reason for use, but don't directly affect corrosion.|so as long as you address the real corrosion creators (ph, ch, csi)
PoolMath, Effects of adding chemicals section. Either desktop or mobile versions have this.Hmm. Is there any information as to how many ppm of salts bleach or muriatic acid adds? I realize it's not salt as in sodium chloride and that all chemicals add salt and all contribute to the whole. It would be pretty easy to log the amounts and have an idea of where you are exactly. Further, does the salinity test work for total salts or sodium chloride only? I was actually thinking about using my inline water meter when topping off. If I did so I could easily know how it would dilute the tub and could have a rough guess of where the chemistry stands.
I shocked it up to 24ppm FC with bleach
That seems a little unlikely. If this was the case, TFP would probably be having people super chlorinate to remove CYA instead of doing often tricky and expensive water changes to lower CYA.This will immediately oxidize your CYA to negligible amounts. You can test to confirm.
You know, Ive thought about this, and the best answer I can come up with, is that there are other benefits by changing water as a 'best practice' recommendation. Removing salt is a big one. But also, everything else that accumulates in pools.That seems a little unlikely. If this was the case, TFP would probably be having people super chlorinate to remove CYA instead of doing often tricky and expensive water changes to lower CYA.
This is definitely out of the ordinary for me, and has been for years now. Always more. Way more. 300% more.monthly losses in a typical spa of 5-10 ppm probably not out of the ordinary,
AndSo, assuming a CYA loss rate of around 0.4 ppm/day in our pools this comes to 12 ppm per month which is clearly enough to be noticeable as the months pass during a swim season. If one shocks the pool, then the rate of loss could be about 2-3 times faster.
every 10F increase in temperature results in roughly doubling the rate of degradation.
