Split off of this topic. JasonLion For a plaster pool, you need to avoid a negative CSI, or your plaster will be damaged. Go to http://www.poolcalculator.com/ to see your CSI. I see that you list an "Auto Chlorinator" as part of your equipment, but you don't list any salt level. What kind of...

Split off of this topic. JasonLion dschlic1, if I have my calculations correct, here is the process involved in the creation of chlorine from the SWCG: 4NaCl + 4H2O <> 4NaOH + 2Cl2 + 2H2 <> 2HOCl + 2NaOH + 2H2 + 2NaCl 4Sodium chloride + 4water <> 4Sodium hydroxide + 2chlorine gas + 2hydrogen...

There are several scaling problems that can result from maintaining a high, or sometimes just positive, Saturation Index. 1) Scaling of Salt Water Generator Cells. Water chemistry has to be carefully managed to avoid cell scaling which can lead to decreased performance or complete failure. 2)...

Phos-Free reacts directly with elemental carbon, nitrogen, boron, selenium, silicon, phosphorus, sulfur, and with halogens. It is designed to remove phosphates. But because it combines with the other elements noted it seems that it may also reduce borates, chlorine and possibly other chemicals...

It seems conclusive that borates can be helpful in suppressing algae. Does anyone know how or why? Any theories?

Originally from this thread, moved to The Deep End. JasonLion Pool Perfect with Phos Free contains Lanthanum chloride and Lanthanum sulfate. Lanthanum is a silvery white metallic element. The metal reacts directly with elemental carbon, nitrogen, boron, selenium, silicon, phosphorus, sulfur...

Split off of this topic. JasonLion Using Jason’s poolcalculator.com shows that your CSI is about a -0.70. A negative CSI means that the water is aggressive or tends to be corrosive. It can damage any mineral or metal based things like screws or ladders. A positive CSI means that the water...

Does anyone know if a water softener will remove Cyanuric acid? I have never tried it. I have always just drained and refilled. Once, I had two neighbors, one with high CYA and one with low CYA; I balanced both by exchanging the water for each until they were equal, but that was a rare...

Continuing a discussion started in this thread. JasonLion Richard, The book that comes with the Taylor test kit does mention some concern for toxicity. I think that it is probably equivalent to using Borates. Since the cyanuric acid level decreases the effectiveness of the chlorine, shouldn't...
