Forum: The China Shop

After accumulating multiple pieces of conflicting evidence, I think it's about time to discuss and investigate the mechanism of how CYA protects...

This thread presents my findings so far on pool water chemistry including the following: More Accurate Calcite Saturation Index (CSI) to replace...

I was wondering if anyone has tried rigging up a liquid chlorine feeding system that injects on the suction side of the filter pump. I've seen a...

In Ben's sticky on lowering TA (http://www.poolforum.com/pf2/showthread.php?t=191), he says that the 4 carbonate-ish (my term) players in the mix...

Here is a link to a paper on the myth of lowering TA by the 'slug' or acid column method. Interesting reading!...

OK folks, Have at it: http://gizmodo.com/gadgets/gadgets/solar+powered-floatron-cleans-your-pool-and-cuts-down-on-chemicals-274836.php

Edit: Just to keep this in context --- this thread evolved to this discussion from the original "Normal "burn" rate for chlorine in a day" thread in...

I have been toying with the idea of adding borax to 50 ppm to see exactly what effect, if any, it would have on stabilizing pH. My borate test...

OK, I'm starting a thread to examine the downsides to a salt pool. Yes, there are many benefits and these have been talked about on other threads,...

I was reading through the Aqua Magazine site today and noticed this: http://aquamagazine.com/render_site.asp?sectionpath=173/183&processor=content...

I wonder what Taylor's TA test actually measures. It can't be the actual amount of the bicarbonate anion, because Taylor Tech warns that you have to...

This is a continuation of a discussion from this post. First, for information about the chlorine/CYA relationship, you can look at this thread. ...

I read the manufacturer’s manual on line and also the patent which is also available on line. Their proposed mechanism of the formation of NaCl...

What is the ideal "HOCL (as ppm CL2)" number to aim for and does it matter what the temperature is if one uses the "Pool Equations" spreadsheet? If...

This thread is in response to the question posed in this thread as it is a technical response (so belongs in The Deep End). The short answer to...

This post is a response to this post where the response is technical so is going into The China Shop. Monochloramine is a weaker oxidizer and...

Theory: SWGs are generally placed on higher-end pools that are more likely to have other high-end features such as water falls, sheer descents,...

There is a product by Natural Chemistry called Instant Pool Water Conditioner shown here. I wrote about this product on this forum in this thread. ...

Nature2 IS too good to be true. See if you can figure out how it works....good luck! What N2 does is dump silver and copper into your water. ...

Ok, I've thought of a great product! A chlorine extender. It will increase the shelf life of your 10 or 12% liquid chlorine. It's actually a...

Why do folks here say that the shot glass method only works with OTO? I'd think that by combining equal parts distilled water and pool water and...

I have to get something off my chest. Mods, move or delete this if you feel it's appropriate. I have to say something about the so called 'sock...

Hi All; Something Carl said in the CYA and Bromine thread triggered some thoughts I've been mulling over. He indicated we need an organized and...

couple o' things: first, what kind of pool do you have? If it is plaster how old is it? Are you only using bleach for chlorination? Second, drop...

In this post Ben wrote the following: While it is true that there is no evidence that bromine combines with CYA the way that chlorine does so does...

Read this in another non-pool forum. Person posted about more efficient pool pumps, and I posted links to pool solutions, then this post showed up. ...

Hi all! I am new to the pool owner category (about 3 months) so I have been doing some research on properly maintaining a pool. In my internet...

I've noticed over the years that when my solar cover is in place, my chlorine levels don't drop as fast. I can think of several reasons for that: 1....
