The "professional" pool company is ding you no favors. With "once a week" pool care they have to use pucks and shock, both of which are almost half stabilizer/CYA.
Leslie's is showing 100 on the CYA test and 100 is the limit of the CYA test - so at this level we are unsure if it is 100 or some number above 100. At this point I would recommend at least a 33% water exchange to get the CYA down. For vinyl lined pools leave at least one foot of water in the shallow end to keep from floating the liner and all pool owners are cautioned that in areas with a high water table lowering the water too much can “float” the pool out of the ground.
Mixing pool store advice/testing with TFP methods is just another recipe for disaster. So, either wait for your pool company to fix the problems or take control yourself. There is no magic answer we are going to be able to give you to fix it.
If you want to take control, order a
TF100 and at least include the
XL option. That will give you what you need while you are clearing the pool, and probably enough reagents for a couple of years normal use.
The only other real option for a test kit is a Taylor K-2006. Be careful comparing prices because the K-2006 comes in sizes, designated by a letter. The basic K-2006 has .75oz bottles. You need to get the K-2006-C to get the larger bottles that you want. Even then it is a little short on the reagent & powder for the FAS/DPD test.
I also have the
SpeedStir and
Sample Sizer. They speed testing and accuracy.
