I understand that the paid version allows unlimited log entries....but what limitation does the free version impose?

Thank you guys for your very helpful replies. You’re right that I’m referring to my single dose of chlorine to SLAM levels as SLAM, which isn’t necessarily a SLAM. I try to hit that level at least once a week as my standard protocol.

Interesting information. I’ve been enjoying not touching my pH for about a month as it’s been really stable at 7.6 every time I checked. So, are you suggesting I should drop my pH prior to SLAM? Won’t I be using far more product dropping pH and then raising once the FC gets consumed and drops...

Any way to confirm it was safe to get in? Would checking the pH before the SLAM have been the right approach and then not worry about the pH effect of adding 0.9c of 10% chlorine since it would start dropping once the FC started getting used?

TA is 70 So, based on the numbers above, would you think just getting in without any pH adjustment would have been fine?

So I’m just over one month into the dichlor to bleach method and have been loving it! I’ve been using 7.55% Clorox and with my total alkalinity at 70, and have been very happy with very stable pH of 7.6. But this weekend I switched to 10% liquid chlorine. Yesterday was my weekly SLAM protocol...

Thanks for the reply. I agree that my temptation is tied to frequent high chlorine tests. Wise advice too

I am new to my Taylor K-2006C kit. I've been measuring my spa several times per day working through some issues... If I'm OK with the accuracy of +1/-0 FC, has anyone else ever reduced the sample size from the smaller 10 ml to 5 ml to use half of the reagents and speed things up? If I used 5 ml...

It's a fairly new spa (November) and I am on my second fill because I learned a lot on my first ;) I had used dichlor exclusively, drove my CYA up quickly and let FC drop to zero a few times! On my current fill, I started Dec 27th. and have done much better with the exception of the CCs that I...

So I recently stopped using MPS as my shock because I wasn't happy with the challenges it's introducing in my chemical measurements. I do have the deox reagent and used it to confirmed that I don't have any residual oxidizer. I have about 2 ppm CC and am struggling to remove it. I'm thinking...

Thanks for those links, I read them and understand better... Well, you kind of answered it....same as FAS-DPD, only with an added step. Is that the step of adding 1 ml of deox with the DPD powder? Is that the only difference in measuring chlorine with FAS-DPD with vs without deox? Otherwise...

Got my Taylor K-2006C this weekend. Unfortunately I'm still waiting for the reagent for MPS interference since I had to order that separately... Couple more questions... Total = Free + CC The FAS-DPD method allows me to measure free, CC and infer total chlorine. Does MPS only interfere with the...

CH was 79

From here

I'm very surprised that MPS is absent from pool math as MPS is fairly common in spas? I have no ozone/UV/generators just me trying to keep things balanced. I've been using test strips, but am ordering either TP-100 or K-2006C per this site. I'm interested to see how high my CYA is. I...

OK, per that link: While my TA doesn't seem low at 100, I keep having to raise pH. I'm also not adding acid.

Spa Choice It's 99% dichlor with 55.5% available chlorine. I know it contains CYA, so I'm trying not to overuse it... I've read that ANY shock product will lower pH. Wondering why that is and if I should be using less MPS?

I received my Bullfrog spa in November. As a previous pool owner, I thought I knew what I was doing. Now I know that I most certainly don't! After adding too much chlorine and shock to my first fill, I ended up draining it and starting over after only 2 months. I had gotten the CYA very high...
