Maybe a silly question, but my FC is jumping around a bit depending on when I test it. Right now I’m testing every morning (before my pump timer has kicked on) and every evening (while the pump is running). I’m mildly concerned because in the mornings I’m seeing my FC decrease overnight by...

Thanks, Chris. I’ve had a CC of 0.5 throughout my entire SLAM, but to make sure I’m measuring it correctly with my TF-100 - after I use R-0871 to get my initial chlorine sample with the R-0870 powder to clear, I’m adding 5 drops of R-0003. Adding those 5 drops turns my sample ever so slightly...

Thank you, Kim! Nice to meet you! So I've been SLAMming since mid last week, and this morning is the first time I've gotten up and haven't lost any FC overnight! Man, what an experience.. the prior couple nights I had been losing maybe 2 FC, and I was starting to think my calculations were...

Just back from Leslie’s where I bought 8 gallons of 12.5% bleach (had coupons built up, that’s only reason why I bought it there!). While I was there had I them test my water sample - they have my CYA at 78. My testing showed 60ish using TF100 this morning. Is it common to have such a different...

Super helpful. Thanks! I’ll go get some liquid chlorine today and make sure I’m maintaining at the correct SLAM ratios. I did reduce PH to 7.2 or so before all this, so that’s good. Clarifier I used is some Clorox stuff I bought at Lowe’s a couple months ago. I’ll lay off using that and the...

Thanks, Chris. I’ve filled in a signature. I tested the FC using the TF100 kit. You can see my numbers tested last night in my first post (FC 20, and CC was also 0 - I didn’t list that). This morning my numbers are: FC: 18 CC: 0 CYA: 60 So some loss of FC overnight. And I see some dead algae...

Hello! New member here. I bought a house with an in-ground pool last year, and have been taking a crash course in figuring it all out. I’m not there yet! But discovered TFP online and have been diving in. I bought the TF100, which arrived today. This summer has been tricky, as I’ve been...
