I closed for my first time today and all the lines were blown out with no problem. However, my spa blower does not run. Will the air blowing out the return line to my spa also pull water out through the Venturi tee on those lines or do I now have standing water in the blower air line subject to...

For some reason I cannot add a link to the forums on my Home Screen of my IPad. it appears to be working when I add it but, clicking it takes me to the general web page instead, I.e. it appears that the "/forums" of the address is somehow being stripped off or is rerouted to the overall TFP...

Thinking ahead about my first closing(maybe too much 😁) and I am wondering about my spa drain. My plan is to clear out and plug all suction lines and returns with the air cyclone into one skimmer, leaving the main drain and spa drain for last. With those lines clear, my MPV set to closed, and...

Which is preferred?

I have 2 skimmers and a main drain. I was planning to do my own closing in the fall using the main drain to bring the water level down below the skimmers. However I just now tried running only the main drain and I get lots of bubbles/turbulence in the pump basket. Otherwise, with the skimmers...

I have paid to have my pool closed in September for 4 years now, and I have never had any algae when it is opened in May. I plan to close myself next year so I just made a point to now look at the empty bottles they leave in my skimmers to see what they have been adding every year. Turns out...

I want to remove an old chlorinator because I don't use it, and the winterizer plug is stripped off and stuck in it. I thought about just ignoring it, but there is about 4 inches of water standing inside the chlorinator which will freeze over the winter. There is about 1/2 inch of exposed...

I added a pound of cal hypo last night by sprinkling it around and this is what I have this AM. I guess my mistake was doing some in the shallow end. Thoughts on how to repair? Pool putty?

Is this ice melt ok for increasing calcium hardness?

This is a follow up to This thread. I recently noticed a small leak between the motor and the pump so I decided to replace the seals with a go kit. Turned out that the impeller was messed up where the eye seal goes on, meaning I needed a new impeller. Well it turned out that nobody had that...

I see from pool math that csi is affected by salt level. Others as well? Is that something I should be measuring in a non-SWG Pool? If so, how do I do that? If not, what is a reasonable value to put for salt on the pool math page? .

I had a little bit (like maybe a cup or two) of granular cya left over from when I did a CYA add via sock method. I am still just a little short of my target of 40 and am wondering why is there a requirement for 24 hours of filter time? What if I just added a sprinkle every now and then? (I...

Should the strainer bracket stay completely full overnight? First thing in AM, pump runs for one or two minutes before water starts flowing, but only two or three tiny air bubbles show up in the strainer. Strainer basket o ring is fine. Replaced drain plug on pump and o-ring on check valve...

When I run a search for “meyco”, I get threads meeting the criteria, but cannot open them. Get an oops message. I am ruing safari on an iPad.

We have had a lot of rain this fall/winter. I checked my CH today and it is really low: 75. Is it OK to add CaCl now even though there is of course no pump running? If so would you recommend dissolving it first? BTW, I did the test with TF 100 kit on a sample that I allowed to come up to...

I just ran a search for “adding calcium chloride”, and none of the result threads come up. I get “oops we ran into some problems”.

I used same people to close my pool this year as it went well last year. They used an algaecide and had me check/add pucks once a month, though not many pucks were necessary over the course of the winter. I want to avoid increasing cya though, so I wonder if I could instead just add bleach...

My DE pressure is 20 after a backwash which I do at 30. It was at 25 recently but today It was surprisingly back down to 20. We have had a lot of rain, so a day or so ago I drew down water using the waste setting. Is there any way that would cause this to change? I also replaced the MP Valve...

Pretty sure I have a leaking check valve on spa return as water level drops over night when filter is off. Is valve pictured a true Jandy Valve for,which I could just replace flipper? Anyone ever tried just replacing flipper using spavalve.com?

The TF-100 Test cylinder only measures up to 100. Are there kits out there that go higher, or is there a workaround to maybe use more reagents and then halve the reading, etc.?

I am a new pool owner as of last June and even newer to the TFP concept. I got through last year with test strips and occasional trips to the pool store. I have ordered a TF-100 test kit, but, being the cheapskate that I am, will not have it for 2 or 3 weeks (pool supply world sale of $63 was...
