We have noticed our pH seems to be rising more than it used too... so we have to add muratic acid every couple weeks (no big deal)... my question is we have a few stains (we just replastered our pool a couple years ago)... I have seen these brushes that have a reservoir to pour muratic acid in...

Background: this isnour 4th season for the pool, this year we just got new plaster and are going through the curing process. Traditionally (past 3 seasons) our pump has produced pressure at the filter of around 12-15 operating.. and I usually backwash when it gets over 15-18 range... as we are...

We are on day 2 of new plaster. We have been brushing the pool 3 times per day... water looks really good already. I have been in ‘slamming’ mode, so keeping Chlorine at 10...my PH was off the charts so I added muriatic acid... the pool guy said I can’t add any CYA yet, for 10 days so I just...

so, day three in the slamming process...pre-slam levels: ph-7.0 (it was between the 6.8 and 7.2, so a bit of an educated guess here) fc-0 cc-.5 CH-150-(added some calcium hardiness, but will need to add more) TA-80 (added the appropriate amount of baking soda to raise the level) CYA-55-60...

Is it a bad idea to have both the tabs and liquid bleach to chlorinate the pool? Here are my latest test results: TC- .5 (based on Taylor basic test) B- 1 ph- 7.2 FC- 1.5 (based on tf100) CC- 1.5 (based on tf100) CH- 175/200 I wasn't 100% sure on this one TA- 90 (today I didn't...

Ok... So I purchased the tf100 XL science lab... I mean test kit. :). I don't know where to start...is there a preferred order I should start doing the tests? Little coaching for this rookie would be great! Once I get the basic tests done... I will post those numbers and see what I need to...
