    Soon to install Edge 40 - questions from an swg new owner

    I’m installing an Edge 40 soon at my father in laws pool. I’m the pool boy - lol. It’s a vinyl pool getting a new liner and with the cost of liquid chlorine and my father in law aging I’ve decided to install an swg. All of the pvc plumbing will get replaced at the equipment as the pool is older...

    Returning user: lots of Old conversations how do I mark them read?

    Edit: I found how to mark them! No need for a reply. I have returned after a long hiatus. I have something like 180 old conversations with notices. If like to dismiss them since they’re quite old. I found a place for alerts that allows dismissal but nothing similar for conversations. Is...

    Just opened the pool... guess what I found?

    Algae! I "closed" the pool last fall using Polyquat per normal methods. The closing consisted of putting on the opaque safety cover and running the pump when too cold to avoid freezing. The cover is a little old and has some tiny holes (less than dime sized) in a few places and doesn't fit...

    Is there data to show that the larger cells last longer?

    CYA test for lower values...

    We have recommended dilution when trying to discover the extent of very high CYA levels. Is the opposite possible as well? If a pool has less CYA than can reliably be measured can you change the ratio of reagent to water lets say 3.5 ml water to 10.5 ml reagent to measure low CYA? My...

    What is the shock level for 0 CYA water?

    This is a tad tongue in cheek... and not a pool related question. I have dog water bowls and cat water bowls that develop algae. The dog water bowl is outside and exposed to sunlight and has more capacity and is changed daily during the summer and less frequently in the winter. Algae builds...

    Can you add bleach using the puck feeder?

    My pool is covered with a safety cover but not closed. I may yet fully close but so far I haven't. If I want to agreed bleach I have an access at the ladder but this is not near a return. Can I stop the pump, add liquid bleach to the puck feeder, and with the feeder flow on high, close it up...

    Booster Running for Unknown amount of time without main pump

    I am an absentee pool maintainer. My Father-in-law owns a house 1.5 miles from me with the pool. He's not at all savvy about the pool - and we haven't closed yet. When it dropped below freezing I set the timer to ensure things were OK and then didn't get back for a couple of weeks - he...

    Water pooling on solid winter cover

    Does sand wear out?

    [Split by moderator - This debate was split from HERE]. Keep further discussion in this thread. Thanks, jblizzle] Use a microscope... I can't imagine sand ever wearing out given the lack of movement and the way sand on beaches behaves. The other info above seems very useful and dead on. Sent...

    When to use a net cover over a solid cover?

    I read in another thread that some people use a net type cover over their solid cover to help remove the leaves - at least that is what I think I understood. Can someone clue me in? I have just covered the 16x32 inground at my father-in-law's house - I'll have to partially remove the cover to...

    Find a way to collaborate with the PPOA?

    The PPOA folks seem to "get" the chemistry of pools. Their methods are geared to large pools but they have a lot of science backing their claims and they might be able to help refine some explanations and provide a way to defuse "pros" who think they know better than the experts here. Nice...

    Flexible vs. Hard Plumbing?

    I have a sand filter with a multiport attached to my pool plumbing using hard PVC. The pool was built by previous owners and seems to have had a few repairs over the years. The plumbing as it is does not really permit removal of the multiport to do any kind of cleaning of the sand or...

    "Mold" in a Tile Shower - Can I use Calcium Hypochlorite?

    I have some persistent "mold" (perhaps black algae?) in my shower that needs to go away. Bleach sprays and mold sprays don't seem to really get rid of it. A lot of the mold is in the caulk - so my plan is to treat around the caulk, strip the caulk and then treat again with no caulk - and...

    Charlotte NC - Pool Closing Options

    I'm in Charlotte - this is my first year with this pool. I'm unclear what is normally done in this area to close a pool. I've seen people recommend a full blown closing (pun intended) and people recommend just running the pump when the temp is below freezing. We don't get hard freezes below...

    Polaris 380 getting stuck...

    I've been mostly happy with my Polaris 380 since getting it. I got a deal on it ($50 craigslist - NEW but old stock) and already had a booster plumbed into the pool so it was pretty much a given I'd try it. For the most part my only complaints are that the thing gets stuck - a lot. The...

    High FC - pH measurement options?

    While I realize that most of the time our stock answer is that pH cannot be measured accurately during any condition where FC > 10; a few members have high CYA and restricted water options. Also some of us would like to know what pH is doing during shocking. From what I understand, the...
