    What are these Flakes?

    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...

    Oxygen Reduction Potential (ORP) Meter

    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?

    Second Visible Algae Event in 3 months

    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...

    Second Visible Algae Event in 3 months

    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.

    Second Visible Algae Event in 3 months

    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...

    Second Visible Algae Event in 3 months

    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...

    Pollen or Algae?

    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.

    Robot Cleaner Use During A Slam?

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

    Robot Cleaner Use During A Slam?

    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.

    Robot Cleaner Use During A Slam?

    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...

    Robot Cleaner Use During A Slam?

    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...

    When is it time to change the filter?

    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.

    When is it time to change the filter?

    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...

    When is it time to change the filter?

    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...

    To maintain your pool yourself - or hire out - thats the question

    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.

    Colder Weather Chemistry

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

    Colder Weather Chemistry

    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...

    Water Balance as the Water Temp Cools Off

    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.

    Water Balance as the Water Temp Cools Off

    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.

    Water Balance as the Water Temp Cools Off

    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...

    Water Balance as the Water Temp Cools Off

    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...

    Water levels, relative to the skimmer.

    Thanks for the advice. I will hold the water for now. Will probably start burning off tomorrow.

    Water levels, relative to the skimmer.

    Thanks for the info. I won't dump any water until it gets close to the coping. I don't think we will see that today. I don't have an overflow port. I don't remember that be offered by my builder. And didn't know to ask about it. But, that would be handy in the event I was away from home during a...

    Water levels, relative to the skimmer.

    Hi All, first time pool owner and the pool is about 6 months old now. I have always heard that you should keep the water level at the midway point of your waterline tile. My skimmer opening starts about 2 inches below the tile, so I have interpreted this guideline to mean keep the water level...

    OCLT Fail-Questions About SLAM

    Thanks. Ok, pool just burned off another 5 ppm in 3 hours during the heat of the day...25 back down to 20 ppm. Basically burned off 10 ppm in less than 11 hours. But thats mostly because of the high level of FC, right? Not as crazy as it seems? It is hot and the pool is getting direct sunlight...

    OCLT Fail-Questions About SLAM

    Merged threads - TFP Mod Went on vacation for 1 week. Upon my return, all was expected except the FC was 2.5. When I left, the CYA was 70 so I was a bit concerned about the low FC. And, I was running an iChlor30 for 11 hours a day at 80%, so I thought I would hold my target FC of 5. I turned...
