After some issues with my pool equipment I am finally able to get the test completed. I'm not sure what all I should test for the Slam. My numbers are
CYA < 20
PH - 8.2
Chlorine - 0
Free Chlorine - 0
Wouldn't it be better to just dump the water and start from scratch. I saw another posting of a guy trying to clear up his pool after trying to clear it up for 32 days, why not dump and fill and start from there. cheaper and easier. No?
Depends on volume of pool, pool surface, water table levels, water restrictions, etc.
While a slam can be done using pucks and bleach at the same time, It is much easier, at least in the learning stage, to add chemicals in a way so that you are only keeping track of one parameter at a time. With the pucks, yes, its just toss and go, but each addition changes chlorine, cya, and ph at the same time. Unless he has a severe ph, updrift then that could actually cause issues with dropping ph to an unsafe low level, especially since ph tests are unreliable at slam levels. I have seen several threads already where people coming off of pucks have had extremely low oh and ta. Pucks would also need to be removed before performing the oclt.Since his CYA is at zero, why can't he just use pucks which will add CYA and is cheap? Add bleach in the evenings to make sure it is killing algae and not getting killed by the sun. A big thing is to get your PH to a good level of 7.2-7.6 and the pool store test should be pretty accurate for PH until you get a good test kit. The pucks are easier if you need to add CYA anyway or if you are on vacation or something.
