I do go to the pool store to get my water tested just as a sanity check, but lately the only numbers I (sort of) trust are CYA and calcium hardness (and maybe alkalinity). They had their machine recalibrated about a year ago and ever since, their results have been so janky, it's mildly...

I just jumped on here to ask the same question. My supply of Leslie's Hardness Plus is running low, and I was wondering if I'm crazy, or is that stuff far from 100% calcium? My pool chem dose calculator gives two dose amounts - one for 77% calcium and one for 100% calcium. I can only assume that...

I'm using pH - Alkalinity Adjustment Tool by Lowry Consulting Group. I thought that was pretty standard at TFP. I use Cal Hypo as my primary chlorine source.

I've been using the pH-Alkalinity Adjustment Tool app for some time now, but I have to admit I don't completely understand what it's telling me to do. I understand there are two sections: pH Priority and Alkalinity Priority. What I don't get is whether I'm supposed to be following BOTH of these...

Makes sense. For the separate issue you raised, I use trichlor only at times when my CYA is a little low and I want to raise it back up. The rest of the time I use Cal Hypo in small enough amounts to just maintain my pool at around 2-3.5 ppm. I find that if I do that, my CH stays in line for...

Good info, folks. #1: I can't have bottles and containers sitting out/around, so they need something to go in. #2: It's Texas. My garage gets insanely hot, so I need to get the chemicals out of there. I'm thinking this (tell me where I'm wrong): - Get a mid-sized to large plastic "deck box"...

PRACTICAL is the key word here. I've read a number of posts/articles on how to properly store pool chemicals. I get it. There's an ideal way to do it. What I need is a PRACTICAL (though imperfect) way that won't be dangerous, catch my house on fire, corrode the container it's in, etc. I live in...

Do you leave your covered caddy outside/plugged in?

I purchased a Dolphin Sigma robotic pool cleaner a couple of months ago. His name is Ziggy, I like him, and I think he does a pretty good job. One thing I'm curious about: the control box is water resistant, but not water proof (i.e., you should not leave it out in the rain.) The phone app...

I'd like to hear opinions on what is the best pool automation system. When I moved into my home last year, I inherited an iAquaLink. Of the reviews I've seen, most people seem to like it, but I am just highly underwhelmed, and interested in possible alternatives. To me, this thing looks and...

Thanks, folks. I take really good care of my pool, so I’m not worried so much about cleaning up algae. My main question is just about whether I can get something good enough that I won’t have to scrub my pool anymore, or at least not every week like everyone recommends. Even with only a 7,000...

Looking for some expert advice. My old Polaris that I inherited from the previous home owners is falling apart, and I’m torn between getting it fixed, buying a new one, or splurging for a $1000 top of the line robot. I have a very small plunge pool with a pebble finish, so lots of nooks and...

Oh, one thing I forgot to mention is that my primary choice of chlorine is Cal-Hypo. Don’t know if that’s important. I know pH should initially jump when I add it, which is why I don’t test anywhere close to when I add it to the water. (Which brings up another unrelated mystery I’m dealing with...

I have a Lamotte digital test kit that I use to test chlorine and pH, but get a test from Leslie’s once a week for my most trusted read. If you mean how much water is turning over (draining/refilling), I’d say relatively little. With the torrential rains we get in Houston, I’d say a lot of my...

- Not new. Pool is about 6 years old. - Refresh my memory- what is CSI? - 7.6 is contrary to what the Easy Pool Chemistry book says? Why can’t I get my pH to a perfect 7.5? - It seems like constantly lowering my pH from 8.2 down to 7.6 is going to take a whole lot of acid and a whole lot of...

Man, I give up! I have done everything right by the book and still can’t get my pH to quit skyrocketing. What am I doing wrong? I just checked my borate level and it’s fine. (I don’t quite trust those strips, but they are showing my borate level as 80 ppm, so if anything, it’s high.) I keep...

One more thing. Everyone is recommending boric acid, but isn't that just basically roach poison? Why would I want my 3-year old swimming in that?

Found a thread that talks about this exact thing. Almost identical result. The recommendation here is to just add acid to whenever the pH goes up, and over time the alkalinity will come back down. Do you agree? https://www.troublefreepool.com/threads/proteam-supreme-plus-raised-ta.214268/

I am testing everything with the Lamotte ColorQ digital system that uses drops (not tablets). I find that it usually gives me a good ballpark reading, with the exception of calcium hardness, which is normally about 100 ppm too low. (No idea why that level of inaccuracy.) I test with that stuff...

I'm a fairly new pool owner. I bought the Easy Pool Chemistry book, read it cover to cover, followed each step meticulously, and was doing amazingly well until I added my borate. I can't figure out what happened, and I'm so frustrated. I got my CYA up to 50 ppm, got my calcium hardness to 362...
