First time testing - check me please

CYA and TA aren't connected, it's pH & TA that are.

Thanks Waterbear, I didn't know that about CYA and TA...

Thanks Waterbear, I didn't know that about CYA and TA...

It really only become an issue with the use of very acidic trichlor where higher TA is needed to keep the pH from crashing dangerously low. With Bleach and other unstabilized forms of chlorine lower TA will actually contribute to better pH stability and slower pH rise. (It is very rare for a pool on bleach, cal hypo, lithium hypo,or a SWG to need borax or soda ash to raise the pH...unless there is something added that drops the pH like too much acid or an overdose of metal sequesterant. The trend is for such pools is for the pH to rise as carbon dioxide outgasses and adding acid is the norm. When a pool is on trichlor and the CYA is very high (Imagine that!) THEN adjusting TA for the CYA becomes more important and it is not usual to have to add acid to such pools unless dosing errors are made with the soda ash.

Bill,
Just a hint with the chlorine test. Use the 10 ml sample instead of the 25 ml. The resolution is .5 instead of .2 which is usually good enough and you don''t use as much of the R-0871 reagent.

Already suggested that in my first post.

Consider it the strength of re-iteration!

Thanks everyone. Alright, so I think I'll take apart my filter and clean it for the 5th time this season! Then once that's done I'll add the CYA as you guys instructed. I can't have the circulation stop every night so I really want to take care of that first. I'll also keep vacuuming the hell out of it. If this doesn't make sense let me know. Thanks again everyone!

If your DE filter is rising in pressure fast then the grids might be fouled and in need of soaking in a good degreaser like TSP or automatic dishwasher detergent.
