    Pool help; air and black algae

    Have you put shaving cream on all the joints ahead of the pump? Have you done all of them at once? It could be that you have more than one leak and the pumping problems won't go away until you have all of them temporarily sealed with shave cream. Given that you've just installed a new pump, I...

    Silky Swim Goodbye DRY

    borax, borax, borax. I took the plunge recently and I must say it is worth it. I'm not positive about the size of the pool but I'm in the 40ppm range or possibly as high as 50ppm and the pool is noticeably easier on the hair and eyes. I may add salt too but I can't imagine the water getting...

    brown spots

    Screws from the enclosure is a good guess since the enclosure is old and does drop screws now and again but this is always around the doors (worked loose from us opening them), I've never found a screw in the pool and I manually vac it if there's ever anything there. I think the issue is that...

    brown spots

    Ok, I tried letting the tablet sit for a good while (washed 2 dogs in the meantime) and to my surprise the spot pretty much went away. It sort of spread out and faded to the point where you probably wouldn't know it was there if you didn't know to look. So maybe it is iron. Assuming it is some...

    brown spots

    To be clear, I am very good about the chemicals. My wife thinks I'm fanatical and she may be right. I might be as diligent as some others on this forum though. I really don't let the pool go for more than a few days, never more than a week, without adding bleach or acid and testing. The pool...

    brown spots

    So I had the plaster (diamond brite) redone a few months back as part of the pool remodel and now I'm finding a few light brown patches here and there. There are a couple on the steps of the pool and a few in the deep end. They absolutely do not brush away with vigorous brushing from the...

    How to add CYA?

    I usually just add some pucks to the floater when the CYA is low but on the few occasions I added it from the bag, I just slowly poured it into the skimmer. I have a cartridge filter and have never had any issues dosing it this way. I would be reluctant to simply broadcast it because it does...

    borax is awesome

    I just wanted to say that I added borax to my pool last night along with the requisite muriatic acid and I must say that my hair today, post pool, was remarkably smooth, easily as good as after a shower. We had a pool party with several kids and their parents over and I wanted the pool perfect...

    pump selection with new solar system

    ok, I may be sold. This pump, as it is, is working the solar well enough. We had a pool party today and the water was perfect. When the pump goes (hopefully) soon, I'm going to upgrade to something a bit better, probably a 2 speed. I really appreciate everyone's input, this has been...

    pump selection with new solar system

    These CEC ratings are really helpful. Wish I had seen these earlier. I know the 'c' ratings aren't right, but should I be looking at the 'a' or 'b' ratings? I have 1, 1.5" line coming from and going to the pool, plus solar on my 1 story roof (8 panels). There's 1 return eye. The maxflo on...

    pump selection with new solar system

    I agree I'm probably overthinking this and I see how the data are flawed, but an estimate, even a flawed one, is better than pure speculation. I'm not positive that the whisperflo will cost more to run than the superflo on high speed. The current draw says just the opposite. Even if the data...

    pump selection with new solar system

    Also, good point about the TDH being responsive to flow. So there's going to be an equilibrium between what the pump can push (flow) and the TDH that is achieved, and this is going to be a consequence of both pump power and plumbing capacity and the latter is unknown. All I care is that the...

    pump selection with new solar system

    I'm crunching the numbers and it still looks like the most cost effective solution is to run the .5 hp whisperflo, if it will be sufficient for my plumbing situation. There's the 2 speed whisperflo but even the smallest one is .75hp which is probably too much and certainly draws enough current...

    pump selection with new solar system

    So I've read the hydraulics sticky and still have some questions. I have a small kidney shaped pool - I've heard estimates of size ranging from 12,000 to 15,000 gallons, it's 15X30 ft, 6 ft in the deep end. The bottom drain was closed by a previous owner. There's just 1 skimmer line and 1...
