    Need a winning strategy for VSP with DE

    Here is my basic maintenance schedule for my VSP: 18 hours at 1400 RPM 4 hours at 2350 RPM 2 hours off I check the sand filter pressure at 2750 RPM (service mode). This ranges from 12 - 20 PSI, backwash around 18 (around once a month normally). I deep-cleaned the sand filter a year or two...

    Return of the low chlorine demanding mustard algae

    OK it seems like this is an annual event for me every springtime. I really have had a tight control on things this year. Here are my numbers currently: CYA: 40 pH: 7.4 TA: 70 My FC target is 3 - 7, and I usually dose it to 9 or so. My daily chlorine demand this time of year is consistently...

    Does anybody make a skimmer basket that lasts?

    I bought a Super Pro Generic Hayward B-152 Skimmer Basket last July and the handle just snapped. It was not being abused; moderate debris pulled out unremarkably. The handle is secured by these plastic pins that are the diameter of a matchstick. I've had genuine Haywards before, they snap...

    Strategy for dosing 3/4-gallon bleach per day

    This is simple and perhaps somewhat obvious. I need to dose 3/4-gallon of 10% chlorine bleach per day and measuring that out evenly every day is tedious. I alternate between a full gallon and 1/2-gallon. But how do you remember which to dose today? You need a spot to save two jugs. Day 1)...

    Green tint after light ascorbic acid treatment

    I filled a sock with a handful of Vitamin C tablets, about a tennis ball size, and whitened up the stairs and skimmer. They weren't even that badly stained. I've done that once or twice in the past, and never had an issue. Now my pool went from sparkling blue to having a green tint. I was...

    Any photos of iQPUMP01 installations?

    Let's see it, the good, the bad, the ugly. The installation of mine was never completed by the pool guy, and it is just hanging there. I'm looking for form in addition to function. The communication wire is way too long, and I'm not a big fan of "lassos". So, I'll need to figure out how to...

    Mysterious VSP priming events

    Hey gang, this is an odd one for me. I've noticed some mysterious priming events with my Jandy VSFHP185DA2A. My schedule is as follows: 12:00 am - 4:00 am: OFF 4:00 am - 12:00 pm: 2000 RPM (Filter) 12:00 pm - 4:00 pm: 2350 RPM (Skim) 4:00 pm - 12:00 am: 2000 RPM (Filter) I have a fountain...

    DE / sand filter pressure phenomenon

    After backwashing my sand filter, and typically add 1 cup of DE. I don't see an immediate pressure rise, and the pressure will typically rise slowly over time. However, occasionally I experience an odd phenomenon. When the pump is running at the low skim speed (2000 RPM), the pressure will...

    Interested in getting another Dolphin...but am I screwed?

    I went through an ordeal last year getting a new liner installed. The pool company had to drain the pool and reseat the liner to fix numerous wrinkles. All that got sorted out, however there is another casualty. In the deep end I can feel a few rocks under the liner. I don't recall this with...

    My pool cloudiness turbidity test

    So, I've been battling cloudy water for the past couple of weeks after opening the pool. I have it reasonably good right now, but I've sort of started obsessing over it. The difficulty with cloudiness is objectively measuring it each day. Here's my system. It requires the water is at least...

    Taylor CYA Dispenser Bottle 9191 darkening

    I bought my K-2006 in 2014 and it's been great. I did notice maybe a year or two ago that my 9191 dispenser bottle got dark. It happened suddenly and made it difficult to use. I always rinse it out as far as I recall and never use it for anything other than the CYA test. Maybe I forgot to...

    Use clarifier in addition to DE in sand filter following a SLAM?

    Hello all! I'm recovering from a swampy pool after removing the cover and have been SLAM-ing for two weeks. This was a rough one. I do get mustard from time to time and maintained mustard algae shock level for the first week or so for good measure (25 ppm FC). For the second week I've been...

    Replacement for Dolphin Diagnostic cleaner

    I inherited a Dolphin Diagnostic pool cleaner which I believe is 20 years old or so. It worked relatively well for my pool but finally died this year. I believe the Nautilus CC Plus is reasonably close, but there seem to be quite a few other models at that price point. The biggest complaint I...

    Two weeks with a solar cover

    So I've had an old solar cover that I dragged up from my basement going now for two weeks. So far so good. I have a technique to get it on and off without too much fuss. The water temp has remained around 80 which is great and today was a wonderful October pool day. Overnight temps have been...

    Sweet, I have a solar cover!

    I bought my house in 2010 which came with a pool. There was blue "bubble wrap" of some sort rolled up in the basement. I deduced a few years ago it was a pool solar cover, but never used it (I assumed it was just rectangular material rolled up). I really got in the routine of doing regular...

    Lowes is rolling out a crappy new bleach

    So the trend in bleach of revolving off-brands, lower concentrations, mystery ingredients. smaller containers, and higher prices continues. Submitted for your approval is "Moxie Outdoor Bleach" which I encountered at the Lowes pool section today. There is no indication of percentage on the...

    Complete newb vacuum question from veteran pool owner

    I couldn't find an answer to this so I'll ask it. I've been re-evaluating my overall pool care strategy due to a severe mustard outbreak this week (resolved in a different thread). I have a manual pool vacuum that I regularly use in addition to brushing. I see the need to vacuum the pool...

    SLAM necessary without corresponding drop in FC?

    I like to have the pool opened by Memorial Day, but made a few mistakes this year. Here are my numbers: FC: 3 - 6 CYA: 30 TA: 80 pH: 8.1 At no point did the FC drop below 3. However, after the rain last week I ended up with a lot of particulates in the pool. I presume some is pollen washed...

    What would happen if bleach went back to non-Cloromax?

    So at the local Harris Teeter the American Bleach Company bleach has been replaced with A-1 bleach. It has a "fabric protection" logo on the bottle, so I assume this is a no-go for pools. I have access to 10% but I like to grab two or three gallons of regular bleach at the supermarket as I am...

    I find the Jandy iAquaLink app odd

    So this Pump Speed Setup page on the iAquaLink Android app is not optimal. I can set the RPM's and duration for the quick clean command, the timed run command, and a few others. But you can't then simply start the quick clean or the timed run from the app. You have to go outside and push the...

    Ten years of pool drama

    Hello! I've been a pool owner for ten years now, and a TFP member for the last six. I can say those have been the smoothest. That said, it has not exactly been "smooth". I am not the original owner of my one and only pool. Here is a summary of the issues I've encountered in those ten...

    Scoping a Jandy VSP SWCG installation

    Hello, I have a JANDY VSFHP185DA2A pump with the iQPUMP01 mobile interface. This was installed last year by a pool company, but the installation was never completed. The iQPUMP01 is just loose and the RS485 cable is just sitting on the ground. I'd like to scope out installing this properly...

    Any experience with Pool Essentials "4-in-1" formula tabs?

    I bought a supply of these at Walmart a while back and run them through my Pentair R171218 Rainbow 320C as a backup. I'd say around the time I started using these was when I started having trouble keeping my chlorine levels up when on backup. I recently refilled my pool and started clean, and...

    Pentair Rainbow bottom feed configuration

    I have my Pentair R171218 Rainbow 320C in the bottom-feed configuration. I normally use bleach but have it as a backup for when I'm travelling. I try to dial it in when opening the pool, but seem to struggle getting the chlorine level up. My CYA is around 30 and I'm trying to hold at 2 ppm...

    Liner wrinkles during install...need expert verdict!

    Hello! I had a new liner installed from a pool company last week who shall remain unnamed. All in all it looks pretty good, however there are some loose ends. The pool was empty on Day 1 and filled by a truck on Day 2, and as it was filling the installer was smoothing out the liner. At the...

    New liner for the 2021 season

    Hello! Here's a photo of my pool which I'm opening today. The liner developed tears starting in 2017 and I was able to patch it each year. It became unrepairable last year but I managed to keep the pool open all season which was fantastic for staying at home. I pulled the trigger on the new...

    Need a sanity check on fill water CYA

    Hello! I'm opening the pool this season with a new liner and a load of fresh city water from a truck. Can I safely assume the CYA is zero? I don't want to burn reagent testing city water. So that puts me at 5 lbs CYA to get to 30 ppm. I did test the TA and it came in at 20 ppm. So I'm...

    Jandy VSP Freeze Protection

    I upgraded to a Jandy VSFHP185DA2A recently with the iQPUMP01 pump interface and the iAquaLink app. I've been through the settings and documentation and can't find any references to freeze protection. The iAquaLink app has a setting for a freeze run time (I forget what it was called exactly)...

    Priming pump emptying pool

    I have a brand new JANDY VSFHP185DA2A and am emptying the pool to prepare for the new liner. I have the skimmer line off and the bottom drain line open. I've been running for four hours at a time or so at 2750 RPM. I'm down to about a foot left (9' deep pool), and the pump doesn't seem to...

    New liner / water refill / metals

    So I have a new liner going on in a week or two, weather permitting. Any recommendations on the refill process? I've struggled mightily with metals in my city water here. I've not been able to identify what it is, possibly iron and/or copper. The old liner looks like heck from the brown...
