Thanks. I will tell him what to look for.

The water looks fine.

Oh...I see your point now. I was using the wrong term. I tested FC at 8 with the FAS -DPD test. Then confirmed 0 CC by adding the 5 drops of R-0003 and no pink appeared. But the concern put in my head from the salesman is that he measured 4 FC and 8 TC inferring I had must have 4 CC. When I...

The salesman used the term Free Chlorine. He said that while I had TC of 8 that his testing showed Free Chlorine was only 4. I absolutely know my son's pool doesn't have 4 in CC because my testing shows 0 CC. So, I am just considering the possibility that there is 4 ppm of bromine/bromide. That...

My son is taking over maintenance of his own pool and I am trying to give him advise. He will be joining TFP and learning on his own, but I am helping him get started. It's a 10K gallon plaster pool, no SWCG. Pentair single speed pump (not sure the size), Jandy cartridge filter. The pool has a...

OK...from other threads I can assume they are calcium flakes. But strange to me since the pool is balanced. Normally my TA sits at around 70 and I never see this even as the pH drifts up to a 7.9. But I added some Baking Soda a few days ago, more than usual so I ended up at 90 TA. Thinking I...

Any idea, what are these flakes on the bottom of my pool? FC 6 pH 7.7 TA 90 Calcium 300 CYA 70 Water Temp 83

Has anyone tried using an ORP meter? If so, where does the TFP method (Chlorine/CYA Chart) tend to keep the ORP over time? Is it worth buying one? Any recommendations?

Thanks for all the input. I will increase my run time and total chlorine output too as the heat is starting to ramp up. I thought I had it dialed in pretty well to avoid any problems while I was gone. Next time I am gone for a week, I think I will add some extra liquid chlorine (a notch below...

I am running the SWCG 75% from 9-5. Was holding good when I left for a week. But, the water temps increased over the week, so that must have increased demand about the 3 ppm I was adding daily with the SWCG. I just thought starting a 8 PPM would give me cushion to stay at 5 or above for the week.

Hi, thanks for the reply. Since the previous SLAM, I have been using 5 as an absolute min for FC. I was holding 6-7 for several weeks and targeted 8 for the week I was away. When I say 6-7 ppm, that is what I see in the morning before the SWCG comes on at 9 AM. I have been running the SWCG...

Hi All, My question up front: Why am I getting algae while following the TFP method? I noticed my 2nd visible algae event in just 3 months after returning from a week long trip away from home. A week ago, in anticipation of the week long trip; I left the pool at these levels: FC: 8 (boosted...

I was not sure if this was pollen or algae because I never had significant overnight chlorine loss. SLAM'd to be sure. Cleaned up nice after a 36 hour SLAM.

That's what I will do. And I will run the pump continuously till it clears up

Yes, I clean it every 2-3 week on a schedule. I have never seen the pressure increase because I clean before it builds up.

Interesting! No overnight chlorine loss. So, I guess my original instinct was correct. Pollen, not algae. We have been dealing with high pollen counts for weeks. On the cars, decks and pool. I have kept the pool water looking OK by frequent manual vacuuming and brushing. Over the last two...

Is it advisable to use a robot cleaner during a SLAM? I recently bought a Warrior SI robot and used used it to clean up what I thought was pollen. But, now I suspect it is actually algae. Pool is at SLAM levels for the night. Will check the chlorine levels before sunrise to check for loss...

Thanks. The filter still seems to be doing the job. I don’t use any additional chemicals. The bands of the filter are broken in a few places, but that would not seem to be a problem.

Thanks Jim, I am cleaning the filter on a schedule, not waiting for any pressure increase. I normally clean it when I have a sense that it has been trapping a bunch of junk. Usually I find it pretty dirty way before there is any pressure build up. Probably I am overly diligent because I see...

My pool is now 1 year old. I recall the pool builder saying that I should change out the first filter after about 1.5 years, after that it should last about 3 years. I clean out my Pentair Clean & Clear 150 at least every 2 weeks. It is an open deck pool and the neighbors have big oak trees...

My pool opened about a year ago. Maintain it yourself. It's easy and no one will care for your pool like you. Read Pool School and get advice here and you will know more than most service people.

Thanks for the analysis. I might do a precautionary SLAM before bring the water temp back up next time.

Hi All, this is my first Winter for owning a pool. I test the basics ever day or every other day so I noticed right away the chlorine demand going down as the days got shorter and water temps decreased and I adjusted accordingly. At water temps at about 65 degrees and the short days (even...

OK. So, sounds like I am good at CH 325 and not to worry about the CSI going a bit low for a while after adding acid. It really only stays low for a day or 2.

Sounds good. I was gonna buy the SI just for the idea of driving it if I wanted. But, I will save the $50 and get the SE.

For sure, if I let the TA go down to 50-60 the Ph would hold at around 7.6 much longer. I played around with that a bit when the water temps were in the 90s in August. But with water temps at 80 deg, TA at 50-60, Ph at 7.6, maintaining 70 CYA, the water is pretty low on the CSI, I think I...

Hi All, I am a first year pool owner and noticing the change in water balance as the water temps cool off, even in Florida. Below is my current test results from this morning using K-2006C/K-1766. As you can see, the water is well balanced on the CSI, but Ph is a little high. I normally catch...
