Thanks for the info on the seal. I went ahead and ordered some Sealube just to play it safe. :)

I'm replacing a USQ 1152 on a Pentair Pinnacle PF-II. I have a couple of questions. First, the manual http://www.pentairpool.com/pdfs/PinnacleOM.pdf shows on page 9 that the ceramic polished face of the seat should be up. I got that part no problem. Then it shows the seal with "carbon polished...

According to Pool Calculator, adding 4 oz of 6% bleach to 40 gals of water gives you an FC of 48. You've probably blown the test system's mind. :D

Just guessing, but one is probably controlled by the dial, and can be set where you want to perform your backwashes, as a reminder. The other is probably a tell-tale that indicates the highest pressure reached on the gauge. You should be able to reset that one somehow as well. Again, just a...

Wouldn't a slide (or more precisely, the force of a person hitting the water) generate quite a bit of uneven pressure on the side walls? Would there be a chance that force is too great for an above-ground pool?

I think I understand. You're saying that in the picture I can see both the pool wall and the decking, as well as the separation between them. The deck moves differently than the pool wall, and that's why the tile cracked. I can see that now, from the picture. So my best alternative is probably...

My pool doesn't have what I think of as coping. Rather it has bullnose tile mounted as shown in the picture. Frankly, it sucks. Without an overhang, water splashes out with even moderate activity. Since you can see from the picture I have some work ahead, I'm wondering if there's a simple tile...

That's a great story, and I've got one similar. I'm in FL, but have a good friend in MI with an above-ground pool. She's always had the late-season algae problem caused by pucks and high CYA, and had no clue why. When we talked on the phone about her pool and she said she had problems, I said...

Maybe it's something specific to my configuration then, but I can replicate it. Maybe it's because the weir's a little stiff but with the cover on there's enough suction to pull it down where it should be and the flow gets started. Once it's flowing I can take the cover off and it still works...

Don't stop now. Finish the shocking process or as soon as you turn your back on the pool it's gonna green up again.

LOL! Let me add another newbie tip: When starting your pump, it's important that the cover be on the skimmer or it will draw air and you'll lose your prime. I chased around for an hour one day trying to figure out why my system, which had worked perfectly for weeks, was no longer able to...

I had a period of a few days during my pool cleanup when things weren't moving very fast. Part of the problem was that I had to clean the filter so often I didn't run it 24/7. When I got the water clear enough it would run overnight, the process sped up a bunch. Be sure you're running 24/7 and...

The pool calculator http://www.poolcalculator.com/ says you should be shooting for a range of 2 to 5 ppm for a CYA of 20. You're at .2, one-tenth of the minimum. Just to get to minimum you need to add 83 oz of 6%. If you've got algae, you should be shocking at a level of 11 ppm, which would...

With 50 ppm CYA, you need to use 16 ppm as your shock level. The levels I mentioned are for my water, with a CYA of 20. If 20% over is acceptable (waiting to hear from the experts) you could raise your FC to 19 before you left to buy you more time. On second thought, you could probably go as...

Re: Newbie about to start Hey, Miami... I'm a bit west and north of you, and I get by with twice-a-week testing even though my CYA's only 20. PoolCalculator says my target range is 2 to 6, and I lose about 1 ppm a day (more if the cover's off, less if it's on). I do my pool work on Friday and...

My CYA's only 20, but I had a similar situation here in south-central Florida. I was gone for a week. I bumped the chlorine to shock level (10) before I left and put the solar cover on, and it was still above minimum when I got back. I let it ride, and I didn't hit minimum (2) until 10 days had...

One of the things I've learned here is that many in the industry are either sorely lacking in specific knowledge when it comes to pool maintenance, or they are intentionally misstating their case to increase revenue. That makes the "appeal to authority" logical fallacy pernicious. I think the...

Two years and 12-16 months clean with a current onset of algae (if that's what it is) raises the CYA flag in my mind. Have you been using tablets to chlorinate? Have you read through Pool School? (Link on the upper-right of every page)

Those look like the "stains" I had. After a couple weeks at shock level (cl 10 @ cya 20), they are almost all gone now. I think it was mostly black algae along with some staining. There's still some discoloration (black on the sides and brown on the bottom), and I think what's left may be some...

I've had the same problem with the pool at the place we bought. Originally I thought it was dead algae, but since I've killed that off, it's gotten better but still not stopped completely. I figure it'll be fine until we decide to resurface.

I'd love to see something definitive. I never know whether to have my cover on or off, depending on whether the sun's shining or not, how the air temp compares to the water temp, how much wind there is... there are so many variables. Should I remove my blue cover when the sun is shining, but...

Well, it was just an idea. :) A solar cover just the size of the pool wouldn't work, as it would float to the top as new water ran off and mixed with the old. However, If you had a solar cover large enough to cover the pool and go down the sides, you'd be isolating the water below from the water...

Buy an oversize solar cover. After you're done, cut it down into a couple of covers, use one and store one for a couple years until the first one dies. I bought a 21 * 42 ft solar cover for my 12 x 36 pool from VMInnovations cheaper than I could buy a properly-sized one from anywhere else. If I...

I let them dry after they're well-cleaned. If they look good after a spray, I let them sit in the shade and dry, then store them in the garage. If they don't clean up, I throw them in a garbage can along with some cleaner and start the process. Once they look good again, it's dry and store time.

Best price I've found was VMInnovations, delivery was quick as well. Here's the one I needed, the 150. http://www.vminnovations.com/Product_16 ... lter-.html It was $64.95 with free shipping. However, don't give up on your old one. I had one I was about to retire until I did the cartridge...

That looks about like the nozzle I used to have that would have worked fine. The one I have now looks different but delivers a similar hard stream. I think a pressure washer has way too much pressure and will rip the cartridge fabric. Second-hand info I seem to remember reading here earlier. In...

There was also a mention recently of getting that plastic wrap they use when moving furniture and taking a wrap or two around the edge of the pool to help hold the cover in place.

You may need a hose end that delivers better pressure. My filters are back to white after I wash them, but I'm using a head that delivers a hard, thin stream of water and we have fairly high pressure here. A light spray would leave most of the dirt embedded in the folds. Also, if you let the...

The shock process can take gallons depending on what's growing in your water, whether there's a lot of ammonia present, etc. Once you get your water changed out and start the process, you can watch consumption and taper off the buying when the consumption starts to decline. You'll want several...
