My friend ended up with a Baker II HR-30 500lb sand filter. It's all new but I'm told sat around for a while unused and empty. He loaded it with 500 pounds of filter sand. I think HTH brand. He's having a strange issue where the system works fine but the pressure shoots way up after 15 minutes...

I was talking with a friend today and the question was brought up, how do the remove the sand from larger filters? The 500,600 even 900 pound sand filters often used at hotels etc, how do they dump the sand out if they need to change it or fix a lateral, or even replace the filter? My 250 I...

As some may recall I stopped covering my pool in the winter. I let the pump run in low speed 24/7 until the water gets into the low to mid 30s, and then shut it down and drain the filter etc. This usually takes place around Thanksgiving / early December. Then, I open as soon as I can which is...

I chose this section because, I think this kind of is off the deep end. Looking at a drawing and requirements for a small public pool I'm amazed at what it calls for as far as filtering etc. Off the top of my head, it's something like 10' wide by 30' long, fairly shallow, like 4 feet deep and...

Ok so I know very little on this subject. All I've used is bleach / liquid chlorine and cal-hypo and I've never touched a tablet but I'm curious, and a friend keeps asking me. I of course add granulated CYA when I need to, but that's actually pretty rare. Why are all pucks / tablets...

My pool water is pretty much always spot on and I work hard at keeping it that way. We're going to be having a few birthday parties soon for the kids and I'm trying to figure out what I should do before, and after. Since they're all younger kids I'm assuming there's going to be a good deal...

I've seen these from time to time, I'm wondering if they are good, bad, or just a waste? https://www.amazon.com/Sun-Shock-Remington-Replacement-Irritations/dp/B07N1XHM31 Remington Solar Copper Anode, 2 x Replacement, Sun Shock Solar Pool Ionizer, Save 80% on Chlorine Costs, Helps Reduce...

I've got an odd question. Does anyone know what the typical thickness of the steel wall is? Specifically I'm looking for what thickness steel a uni-bead liner is intended to go over. My pool is assembled so I have no easy way to get a measurement.

Usually..I measure my pH a few times a week and it's stable. If it's high, which is usually my case if anything I'll add a few hits of muriatic acid, no measuring just a guess and I'll let it circulate for a few days and do a few tests before doing anything else. I usually take my time with...

Hi all I started closing without a cover in 2021 so this is my second winter doing it this way. The pool is clean and it's thawed right now but won't be again by tonight. My pH is 7.0, I think. That's as low as my 2006 kit goes so. I don't know if it's lower but it certainly matches the 7.0...

I'm curious if I'm the only one that barely uses most of my K-2006 kits and if there's a miniature kit out there with only what I actually use. To be specific most of my uses are with the R-0004 for pH and then the R-0870 and R-0871 for chlorine. On a rare occasional I'll bust out the ol'...

I'm probably going to be draining a few inches below the return and draining the pump and filter this weekend. We're supposed to be constantly in the mid 30s during the day and low 20s at night for a while so I'm thinking it's time. Most of the leaves are down. Same as last year I'm not...

So, I know this is an issue but I don't know how much of an issue and when. From what I recall, if your fc is above 10ppm the pH measurement will not work correctly. Is this true? My fc measured 8.2ppm last night and I checked my pH 4 times and all 4 times it came up high. I'd call it...

This for the most part sums up what I need to add to my pool for the past 5 years. Most of the time I don't even test, I just pour some in and I seem to be pretty good at judging the size "swig" the pool needs every 2 days. I probably test my water once a week unless I suspect an issue...

I'm completely baffled right now. I pulled my filter apart because it's been working pretty terrible and I found the laterals had worked their way up into the multiport quite a bit and I guess kinked the top of the pipe? Either that or it kinked from me twisting it trying to get it out. It...

So I've neglected my pool for a while due to some things going on. But I kept my FC at a reasonable amount. Typical: CYA 40 Ph : 7.6 FC : 4 I ignored it besides keeping my chemicals right. It needed a vacuuming bad for over a month. I finally got around to it today and most of it was a...

I thought I had asked in the past, but I can't remember and I can't find the thread. So, I'm sorry my memory isn't the greatest. Are there any obvious downsides to using cal hypo as your everyday chlorine? It's obviously far lighter to carry than bleach, but what are the negatives? I...

I'm curious which pumps seem to last the longest without help. I have a Hayward Matrix 2 speed pump that's going on it's 4th season. I run it from April-December 24 hours a day in low speed. I'll be replacing the O rings etc but other than that I think it's going to be ok unless the pump...

I just wanted to share the results of my first winter without a cover. I kept the leaves out as best I could in between thaws and I needed to be very careful about maintaining the water vs ice level because I left my stairs in. I also learned that the stairs needed to be unbolted from the pool...

So every year I close our pool fairly late in the year and then open it fairly early. I try to keep the water temperature low and so far I've yet to have to even vacuum the pool when opening. That being said.......how big of a surprise am I in for if I wait until most leaves have fallen and...

Hi all Looking for some thoughts.. Over the past 2 months my pool hasn't had much loving. The water temp hasn't gone above 65 or so but I've been on top of my chemicals. My FC never dropped below 3ppm, my pH is a solid 7.6 and my cya is 30. I have a 2 speed pump and a 250lb sand filter I run...

I've always read that once a liner is installed you need to keep the pool full or the liner will shrink and likely not -re-strech. Can anyone provide a little more detail on that? I.E. how old is old? Would a 4 month old liner likely be fine if removed and reinstalled? Are there any tricks...

Hi all, My boss is asking me if there's any affordable and practical way to actually filter urine, and whatever chemicals urine breaks down into out of a pool from fc. I'm guessing something like an RO system could do it, but I'm sure that isn't affordable for a swimming pool. Charcoal...

Hi all, I don't recall this being talked about but I wanted to ask about something I noticed recently. I'm using a Hayward Matrix 1.5HP 2 speed pump. A good friend recently bought a AquaPro 2HP pump. I compared 3 pumps. My dad's Hayward Powerflow II 1HP from 1990 which stated 12A @ 115V on...

Hi all, A good friend is filling his pool with relatively clean water from a stream to avoid using his shallow well. The water is going through a 50 micron filter before going into the pool. I felt once it's full he should get his FC up to 12ppm and start adding CYA. He's going to get me a...

Hi all, So I ran out of time and didn't get what I wanted to done today and I want to know what's best. I raised my water level and got my pump running but didn't get the winter cover off yet. It looks like rain for the next few days. Should I add some bleach or just leave the water alone...

I guess sooner or later I'll get the pool closed. We're getting down to 25 tonight. The good news is we finally got the stairs out, and the water will be good and cold again when I put the cover on.

Hi all, If I decide to replace my skimmer face, do I need to worry about the liner pulling down from the opening when I remove the screws? I have a Hayward widemouth skimmer and this is the pools second season. It's a steel wall with a 20 mil liner.

I'm not sure if this is the best section for this, but it's something I've wondered about for a while. How cold could it get out before a pool had an issue, assuming the pump runs 24/7? I'm thinking the first thing that would happen is ice would film over the top, but at what point would it...

Hi all, I'm not sure the best section to post this in but it seemed to fit the deep end. Is there anything that can be done to make a pool easier on sensitive skin? My youngest has eczema and often scratches up a storm after being in the pool. I'm told water often does this in general but...
