Howdy TFP, I am looking for advice on the attached test results. I opened my pool recently and my pH is 7.2 and TA is 30. Apparently the last time I measured TA was last summer and it was 50 at the time so has come down some. TFP recommends a TA of at least 50 so I am wondering if I should go...

Howdy, I am having a difficult time fully verifying that this is sand coming from my return jets. It is definitely sand that I pick up in my vacuum however when I put a skimmer sock over my return jets, somehow it never gets caught in it. They’re always clean when I take them off. And yet, as...

Howdy, this may be a dumb question but is there any harm in using the switch in the attached photo to turn the pump off for whatever reason such as when I need to change a skimmer sock? It’s much easier and quicker versus using the buttons on the control panel and the pump just resumes the...

Howdy, I just did a full test of my water, first of the season, and my results are attached. I see that I probably need to increase my CYA a bit however my pH is a bit low also. Will adding CYA lower my pH any further? Do I need to add baking soda first to increase it a little? The app suggests...

Wasn’t sure where to put this but I have a couple of questions. First, is there anything I can use to fill in these gaps between the coping and also the skimmer housing and the concrete deck? Some of the coping gaps are much wider than pictured here. I have noticed that debris such as leaves...

Howdy TFP, question on chemical levels for closing my pool. Below are my most recent test results. I’ve had a low level algae issue so have been SLAMing the pool recently, that’s why the chlorine is high. The pool is crystal clear otherwise, just what appears to be dead algae on the floor in the...

Howdy all, I went out to test my FC tonight and heard what sounded like a waterfall in my skimmer basket. I can’t post video but it was like the basket wasn’t full and water was forcefully pouring over the weir door. It wasn’t until I stopped the pump for a minute and removed the skimmer sock...

Good morning, is it normal to have a very small amount of sand collect at the bottom of the pool overnight or over the course of a few days if you have a sand filter? Or should there be zero sand from the filter make its way into the pool? I am a first time pool owner and had a used sand filter...

Howdy all, I’m in the middle of a SLAM (day 6) and my pool is looking pretty good but I still haven’t passed all three tests. That said, I opted to get in it today (hopefully that’s okay) and I am noticing what feels like sediment caked on the walls that is extremely difficult to scrub off...

Howdy all, is this a vacuum port? Can or should I use it for my manual vacuum or is it better to use my skimmer port? I only have one skimmer and no main drain if that matters. How about something like this? Does anyone have any experience with it? I would prefer a robotic cleaner but the one...

This might be a silly question but I am in the middle of a SLAM (day 3) making really good progress. I am testing frequently, every 1-3 hours. If any given FAS-DPD test shows 9ppm, do I need to immediately add the recommend amount of chlorine from Poolmath to try and get back to 10-12 or would...

Would anyone mind recommending a good variable speed motor for a Pentair Whisperflo High Performance pump? I acquired a used one recently with an old, non-original 2-speed Century motor that someone suggested may be underpowered for the pump and will have a limited lifespan when running on its...

Hey everybody, I just had my sand filter and pump replaced and although it seems to be working well overall, there is a strange crackling noise around the multiport valve when running on high. It also lost prime a few minutes ago, although I did have the pump off for a few minutes prior. It...

Good morning, I just remembered that my electrician told me a while back that he didn’t think my pool was bonded and suggested that I have a “water bond coupling” installed so that he could run the bonding wire. Any idea what part he is referring to and where it needs to be installed? I asked a...

Hey all, I am looking at purchasing a robot pool cleaner and am curious if anyone has attempted to take advantage of a credit card extended warranty. They all have verbiage to exclude things like “Boats, automobiles, aircraft and any other motorized vehicles or water vehicles.” This seems to...

Good Afternoon, could someone recommend an adequate robotic pool cleaner for a roughly 36x18ft in ground vinyl liner pool? Would the Dolphin S200 be sufficient for that size pool? Are there any specific Dolphin units or other brands I should avoid? Thanks, Mike

Good evening! First time pool owner here. I recently started diving into this pool stuff and am getting ready to tackle my first SLAM. I opened another thread in the algae channel about that. I started running the pump on filter mode in advance of the SLAM though and noticed my filter is leaking...

Good evening! My name is Mike Stocker. I am a first time home/pool owner living in the upstate of South Carolina. I just want to say that I am happy to join the forum and that this website and forum are awesome. I am so glad I found it before I spent hundreds or thousands of dollars having my...

Good evening! New user here (and new pool owner), I’ve been scouring this website and forum for the past couple of days and it has been incredibly helpful in learning about how to maintain a pool. I’m still a bit confused on some things though and could use some advice on how to tackle my first...
