Balancing Water Before SWG Install Help

Yes it can, but that is the test that is hard to find a supplier. Most people in the US buy it from on-line retailers as most pool stores do not carry it. The K-2005 is a good test but is missing the FAS-DPD for accurately testing chlorine to 50 ppm.

Well, I tried and the store system could not do the transaction.

This normally happens when the company has their system to accept only cards from Continental US.

Since you are not trying to clear up a green pool you are not in real need of the test at the moment. Search amazon and see if there is a retailer that will accept your credit card, if not, get your Florida contact to get you the test.

Thanks!
I should be going to FL next month so I'll make sure I get it.

Ok, just tested Pool Water:

Free Chlorine= 1.5ppm
Total Chlorine= 1.5ppm
Combined Chlorine= 0
Total Bromine= 3ppm
pH= 7.2ppm
Acid & Base Demand not done as pH is low
Total Alkalinity= 40ppm Calcium Carbonate
Calcium Hardness= 150ppm Calcium Carbonate
Cyanuric Acid Test= 80ppm CYA

Please feed back

Thanks!

pH is fine. TA a little low.
CYA is fine for a SWG pool, but your FC is too low. You should not let it get below 4ppm: pool-school/chlorine_cya_chart_shock

What is your pool surface? Your CH may be low if it is plaster/tile/pebble/etc.

Hi!
Its plaster and not SWG yet (will be in 2wks)

Thanks!

Well, certainly do not use any more stabilized chlorine (trichlor or dichlor) or you CYA is going to get too high. Using cal-hypo would bo OK since your CH is pretty low.

Since you do not have a SWG running yet, then you need to be maintaining the FC above 6ppm at all times.

Thanks!

I will get some cal-hypo today (I was using Trichlor).
