FC 15 CC 0.5 PH 7.8 TA 100 CH 100 Cya 30 Sat -.1 Graduation pool party in 3 days. Pool is somewhat cloudy due to very fine dirt or pollen which accumulates in the little divits on the steps, and seems to pass right thru the sand filter, even though I’ve been adding DE to it. Yes, it’s...

Background: It’s been cool here and the pool hasn’t been used. The pool pump has been OFF for the past week. The water has been clear and balanced the whole time. However, there have been drifts of something I call pollen-dust in the vinyl seams and ripples all summer. It can be eliminated by...

I have a new Aquabot S300 which worked great all summer UNTIL we were hit with super-fine pollen. As I watch the robot roll over a pollen “puddle,” a plume of pollen shoots out the top with the discharge water. I’ve tried to find out whether a finer mesh bag is available, but I’m having no luck...

My CH is 50, and I'd like to raise it to the recommended 100-400 level. Sent DH to store for calcium hypochlorite, as we also need to add chlorine and I thought, kill two birds with one stone. The product DH brought home is 50% calcium hypochlorite and 50% "other ingredients." The SDS says...

I've been reading TFP posts about getting the smallest pump with the biggest filter for the cleanest water and best efficiency, and I need advice. I'm ready to get a new filter (current Hayward S200 leaks due to hairline cracks around the dome, and Hayward no longer sells just the top half). I...

Our Hayward S200 sand filter is leaking from hairline cracks in the plastic near the dome. Apparently, Hayward no longer makes the top half of the filter, so replacing just the leaking part isn't an option. Fortunately, our Centurian B128 1hp pump still works, so we're looking at replacing the...

I closed the pool with CYA at 33 last year. I have often opened to 0 CYA, but not this year ... This year, when I tested the water at opening, it was not clear (so, not 0). But, it was also not cloudy enough to read the lowest number on my Taylor test kit, which is 30. So, the number is...

The concrete apron around our 20+year-old in-ground pool has sunk considerably, with one portion 2" below the other portion. The coping is fine, however, but it's causing falls and stubbed toes and has us worried about long-term issues. Enter "concrete lifting." A company nearby drills holes in...

I would like to accurately test my CYA level using the Taylor 2006, but the CYA reading only starts at 30. I'm currently testing at "somewhere under 30" after refilling my pool (new liner) and adding stabilizer conservatively three times and waiting a week for the results to show. I would much...

I may have stumbled across a fast way to dissolve granular CYA. Long story short: New pool liner, needed to add 3 pounds of granular CYA. I put about half that amount in a sock (being conservative), and hung it in the pool water near the shallow end return. At first, lots of powered CYA came...

Opened the pool yesterday, and everything seemed okay except a small leak from the top of the sand filter. I shocked and balanced the water, then left at 3pm. When I came back about 7 hours later, the water was barely clearing the skimmer. I quickly turned off the pump, thinking I had narrowly...

So, we have pollen in the pool after every rain. We've got a method for dealing with it: add DE to our sand filter, vacuum up the little pollen puddles, and backwash the filter. However, due to all the pollen and backwashing in June, the pool is now low in CYA. I would usually add it in a...

First off, this is my sand filter: Hayward S200 side mount with clear plastic dome http://www.walmart.com/ip/Hayward-High-Rate-Side-Mount-In-Ground-Pool-Sand-Filter-S200/44591448 Background: The sand filter was not leaking before we deep-cleaned the sand by unscrewing the plastic dome on top...

Ugh. DH added about 12 ounces "clarifier" (cationic polyamine solution and N-Alkyl Dimethyl Benzyl Ammonium Chloride) to our 26,000 gallon pool. (I might add that he did this without running it by me first.) His intention was to get rid of the pollen we have in puddles on the pool floor...

I seem to have a very small leak coming from my pump or the plumbing near it. I can't find the source. I know it's not one of the two plugs in the basket case (not sure that's the right term, but oh well) because the area near the plugs is dry. Any ideas for finding the source? The area...

I want to deep clean (or at least rinse the sand in) my Hayward S200 sand filter. Do I need to isolate it from my system if I have an inground pool and the filter is above ground? If so, how do I do this? (I will need very simplified instructions. The multiport on my S200 is on the side.)

Before you jump to any conclusions: I've been BBB for years. I got algae after days of heavy pollen rains one week ago. Since then, I have been constantly testing my water, keeping the FC level at mustard algae numbers, using skimmer socks, brushing the pool, vacuuming out pollen after it...

I have my pool "professionally" closed every year, but I open it myself in the spring. This year, I noticed that instead of using the Gizzmo, a standard plug was capping off the pipes in my skimmer. And, for some reason, an empty but capped bottle of pool antifreeze was sitting on top of the...

Our liner has been through 7 seasons, and 6 of them have been BBB. We just closed the pool, and although there has always been some liner fading each year below the water line, it's much worse than usual this year. It starts at the water line and seems to go down the side, but doesn't affect...

Long but very, very important post: Recent Tragedies Put New Focus on Shallow Water Blackout By Michael Popke — AB Managing Editor The July deaths of two 21-year-old men in a Staten Island, N.Y., public pool brought increased attention to shallow water blackout — a largely unknown and...

My dd :wave: has an idea for using our backwash water, which currently drains into a rock garden with various plantings. She would like to put a decorative pond in the rock garden, which would be filled up and occasionally flooded by our backwashing. I know very little about those small...

Our Teledyne-Laars gas heater is suddenly leaking water (not too bad), and DD's pool party is on Friday! I haven't started the gas flowing to it yet, because we've had unseasonably cold weather. Repair people might make it here by Thursday, might not ... do I dare trying to turn it on? Are...

Spouse and I are debating whether it's possible to raise the pool temp by 50F (or more). Is the amount of heat a pool heater is capable of generating essentially endless? Or is too much heat lost into the cold air and ground surrounding the water, so (for example) you can reasonably expect to...

I usually open the pool but let "the professionals" close it ... and although we've never had a problem unscrewing the plugs on the returns before, the "pros" seem to have applied extreme torque last year and we can't even budge them this year. No call back from them yet ... so I'm turning to...

I've never rinsed or cleaned my sand filter in the 4 years I've owned the pool, because I'm unfamiliar with the equipment and loathe to pay someone to do it. At this point, it's either channelled or dirty because the water returning to the pool has bits in it. (Great technical term, "bits.")...

Long story short: Just after vacuuming up a bunch of pollen, I blew an electrical switch and had no pool pump for 4 days until I could get someone to fix it. (I don't mess with electricity and water.) My pool turned green, so I brought it up to mustard algae level for 24 hours (just in case)...

Hello everyone! I've been BBB since I became a pool owner, and I open my own pool, but have the pool store close it down. I used a new pool store for the closing last year, and they seemed to add more antifreeze than usual. I thought nothing of it at the time. However, I just learned that I...

Bought a Blue Pearl robot last summer through Woot, and after one year of happy use, it seems to have suddenly broken entirely. Our best guess is that it's the drive motor -- it will barely go forward, won't go backward, won't climb walls, etc. Of course, the warranty just expired 3 weeks ago...

I've tried to attach a photo of the little orange spots that are all over my fiberglass steps. I've tried the vitamin C tablet and it doesn't work. I think I need to purchase a metal sequestrant but have no idea which one to buy. Help!

I just bought a Blue Pearl, and I'm wondering if it's safe for all the parts to leave it in the pool overnight? I'd like to start it running before going to bed, and then pull it out in the morning. Also, I'm wondering if it's safe to have it clean the pool while the pool is being shocked...
