unclefudgly Posted March 6, 2010 Report Share Posted March 6, 2010 Hi all I hope the mods will allow this shameless plug as I think a few people could be interested, there's a new app in the app store called hotTub&pool for doing lots of pool calculations. Also has a really good waterbalancing feature to calculate LSI (Langelier) index. Would be great to get some feedback from all of you with all your years of experience.

chem geek Posted March 6, 2010 Report Share Posted March 6, 2010 The Pool Calculator does the same thing, only better (it actually does more). It is also available as an iPhone app in addition to being on the web. Were you not aware of this application? Quote Link to comment Share on other sites More sharing options...

It does seem to be very informative , but also a bit confusing and no water balancing at all as far as I can see. Horses for courses hey? Always good to have a choice I think.

chem geek Posted March 7, 2010 Report Share Posted March 7, 2010 No water balancing? It calculates the calcite saturation index which is actually a more accurate version of the Langelier Saturation Index. The CSI essentially matches the Taylor watergram (but also accounts for different TDS levels, so useful for saltwater chlorine generator pools as well) and is also close to the ANSI/APSP-11 standard that has a revised saturation index calculation. You are probably using the older LSI formula that is found on most pool websites and is wrong in both its temperature compensation and in its accounting for TDS (ionic strength). Did you look at the description of The Pool Calculator in the App Store on your iPhone or at this link (clicking on "...More" to see the full description) and see that it says under "Available calculations include: ... Calcium saturation index (CSI, similar to LSI)"? Confusing? You just enter in your current numbers, put in your goal numbers, and it tells you what you need to do. How is that confusing? It explains the effects of adding different chemicals. And the pH adjustment calculations take into account the TA level -- you need less acid/base to move the pH at lower TA levels than higher TA levels. I didn't write the app, but think that Jason did an excellent job with it. Quote Link to comment Share on other sites More sharing options...

Just put in the numbers you have, then the numbers you want/need and then tweak them to get the CSI as close to 0 as you can. I love having more knowledge about pool balancing than the people at Leslie's...which isn't saying much. Also, read the Complete Guide to Pool Maintenance. Easy to read and understand about what each of these balancing chemicals mean and what they are capable of doing. Quote Link to comment Share on other sites More sharing options...

Levels not on a dip strip. whats the best tester to use to cover all those bases. Coop Quote Link to comment Share on other sites More sharing options...

PoolGuyNJ Posted April 21, 2011 Report Share Posted April 21, 2011 www.poolcalculator.com works with Android based web browsers. I use it and point my customers to it too. Until the people that bought the app-store version makes a native android app, the web version works well enough for me. The only reason I will switch is so I am not dependent on internet access, whether that is via my carrier or wifi availability.

zambono Posted January 29, 2012 Report Share Posted January 29, 2012 Pool Calculator will work on any device since its web based. There is also Pool Boy for iOS devices, iPhone, iPad in which you can set maintenance alerts. itms://itunes.apple.com/us/app/aquaplanner/id454175341?mt=8 Quote Link to comment Share on other sites More sharing options...
arches2 Posted May 17, 2012 Report Share Posted May 17, 2012 i started using the android app Pool Pal. it's free and correlates well with the pool calculator. Plus you can create a log of your last 20 readings (though you can't add notes on chemical additions which would be nice). it's a good alternative for us android users.

Spanky Posted June 6, 2012 Report Share Posted June 6, 2012 I have a record of my past year and can even make graphs and charts.... It's called Excel... works on my laptop and can switch back and forth between the pool calculator by simply hitting "Alt" + "Tab" Quote Link to comment Share on other sites More sharing options...
