New Intex Pool owner

[chem geek]

The calculator that we're using is called bleachcalc, and it was developed by mrsmith, a former member of the forum, and further refined by a current member of ours, chem_geek.

Just FYI -- I helped with The Pool Calculator, but didn't have anything to do with BleachCalc. Michael gets all the credit for that app. Note that there is one error in the app with respect to borates so don't use it for that calculation; for everything else, it's fine.

My mistake...... I stand corrected.

So it looks like my CYA is almost 30 ppm now but not sure cause test tube starts at 30 and I can still kinda see outline of black dot.

But I just wanted to confirm that based on the Best guess chart, if I my CYA is between 30-50 ppm. Then I want to have the free chlorine between 3.0 and 6.0 ppm?

Think i need to get that FAS-DPD add on kit then cause mine only goes to 5.0.

Also If I wanted to support the forum, is there a link i could click to purchase the appropriate unicel (A) filters on Amazon?

Thanks again. You guys are amazing.

Yes to keeping the chlorine between 3-6. The FAS-DPD add on kit is K-1515. I'm not sure about a link for the unicel filters. I'll see if I can find out for you.

I think that if you click on the Amazon link to buy a test kit, and just search from there, Ben still gets the credit for anything done during that shopping trip....

Ben, please correct me if I'm wrong!

It's hard to find the right filters -- on Amazon or elsewhere. Non-Unicel filters from Pleatco or other Asian sources are being sold as 'equal' filters, and the descriptions include the word "Unicel", like "for Unicel model C-4607".

Here are the right links:

Unicel C-4607 Replacement Filter Cartridge (Easy Set Size A or C) @ Amazon
Unicel C-5315 Replacement Filter Cartridge for 15 Square Foot Intex B Filter @ Amazon

Currently, the 'A' model is not available from Amazon directly, but some 3rd party sellers have it at similar prices.

Thanks Ben and all,

Will you guys get a piece of the action if I use the links you just gave me above? Or do I use the test kit link then find these items?

Just would like to help out if I can.
