    safe amount of chlorine with solid pool cover

    Hi there. I've been told by cover reseller chlorine is not good for a solid pool cover. Is that 100% accurate? I occasionally have strong winds, which get under the cover and raise it up a couple feet (rubber straps) and then pushes it down. I usually put cover on my pool late October, but I...

    I got this slightly used motor late spring and it was super quite until about a month ago. Also got new impeller with new ring. Now I hear some noise (video) (audio) I think in impeller area, but not 100% sure. Pump basket is new, no holes in it. Could chipped concrete paint (link) be causing...

    pvc bushing leak

    I cracked the bushing when I tried to tighten the spigot. Then I covered cracks with epoxy which lasted for a few years, but it leaks now when pump is on and sucks air into filter when pump is off (but not into pump, not sure why). I don't need spigot, want to remove it and use some plug (like...

    Shaft seal brand? Lube teflon vs silicon?

    Hi there. I'll be replacing shaft seal on my hayward northstar. It looks like the one I need is spx3200sa or ps-3890, but I want to reconfirm with Hayward since the one used before (I believe hayward spx3200sa) leaked the next or the following season. The other part mentioned on inyopools is...

    Does PH level affect chlorine usage?

    My pool water has been crystal clear for the last 3 months. I test every night with 870/871 and add the correct amount of 12.5%. For the about a couple of months I needed to add between 2qt2c-3qt1c of 12.5%, except for days when we had no sun. My ph is always high I rarely adjust it and...

    Pool cover damage please see link above. The cover is about 16 years old. It has lots of gorilla tape patches (not sure if damaged area was patched), but I really hopped it'd last a few more years. We had more snow than usual this winter and I may have lowered the water a little too much -...

    Solid Pool Cover damages mostly on one side

    Hi there This cover (link) is about 15 years old. For some reason it is severely damaged on one side only, the other side is in much better shape. Does this type of cover need to be packed a certain way when removed? I don't remove rubber strap and bolts but I doubt it'd result in this type of...

    Leslie's now has this electronic test tool, looks like LaMotte.

    I'm not sure if it was mentioned before, sorry if it was. I tested water at two locations and reading were almost identical. However, some readings on this tool are very different from Taylor - CYA is about 30-40% higher, CH 30-40% lower. I think the reason they switched to this tool is for...

    interesting observation

    I just opened my pool late afternoon. Added 7 gallons of 10% Walmart chlorine (Pool Essentials) from October 2019. 4 hours later I get 19 FC . According to pool math it is 6% (maybe higher since I tested about 4 hours later). Not bad for 8+ months old liquid chlorine.

    Hi there. What should I use to fill the gaps ? I used Vulkem 45 for the gap between coping and deck, it worked well, but a few years back I was told Vulkem no longer recommends it (or any of their products) for the pool (don't remember where I heard that from, either the pool company I bought...

    Adding calcium chlorine to the pool

    My level is about 200 ppm. Can I use this product (pictures attached)? It contains calcium and sodium chlorine, which I guess is not 100% calcium. If I should not use it, I already dumped about a pound of this product into the pool. Should I be concerned? Thanks.
