    Safe to run with HIGH (but "incorrect?") salt level?

    Just replaced T-15 with a generic one (Pureline) from Inyopools. - the SWG salt level is around 4400 - 4200 (runs at 4200 but shuts down at / above 4300) - Taylor (K1766) indicates 3400 (i.e., 17 drops) If the SWG runs at 4200, should I run it or am I risking the transformer getting too hot /...

    1700 (AquaRite) vs. 3400 (Salt Tester Kit) - is my cell going / gone bad?

    - My cell is 5+ years old but living in NE, we use the pool 3-4 month at best - Suddenly, the salt level dropped from 3400 to 1700 in a day - acid-cleaned the cell but no changes - I suspect the cell may be "bad" 1. Does the cell actually measure the salt level? If the cell is "bad" (e.g., the...

    Can ascorbic acid's efficacy be "delayed"?

    Been fighting with the brown, metal stain for a few years and obviously sequestrants work (I found GLB to be the best) - no well water but I know our city water contains some metal / iron as our toilet's get stained. What I found interesting (and experienced for the first time) is that ascorbic...

    Ant nest? Pour in some concrete?

    I think I have tons of information around what to spray, etc. for these ants from this forum. Now my question is: 1. should I pour in some "less-thicker-than-usual" concrete down this hole?

    Let the Games begin! Jack's Purple Stuff and/or GLB? The Best Time??

    'Tis that season again....and took 5+ days and 15+ gal of liquid chlorine (more than usual) to clear up the water, which is a bit more than usual (mostly due to us being lazy to fill up the pool to vacuum most of the algae/junk). 2022 season was awesome (basically no work) while 2023 was a...

    CYA - can you lose it?

    Any insights on why my CYA is dropping although I am adding more? We did have a few (2 inches?) of rain during that storm around July 4th but I also added more after that....

    Is this normal?

    Going through SLAM. 1. Cleaned the pump filter last week 2. Backwashed and re-filled DE 3. When I dumped DE into the skimmer, I noticed white powder coming out of return jet (not the typical salt-based Chlorine) 4. Just opened and saw this - I think everything is intact Not sure why DE is not...

    Can a pool heater (and/or its heat exchanger) cause rusty water?

    Did some research and was not 100% sure whether an old pool heater (Rome Industries, AquaComfort S95) can cause rusty water (e.g., the heat exchanger is rotted) - I thought I "fixed" the issue by repairing rusty wall behind my liner last year but the rusty water is worse this year - posted by...

    Almost giving up on the rust treatment

    I thought I "fixed" the rust issue by repairing the rusted area around and behind the skimmer. I removed the liner, brushed the rust, treated with CLR, used POR15 (including metal treatment and the "paint"), doubled up on the skimmer gaskets and even applied some "waterproof" caulk around the...

    Pool equipment pad panel / paneling

    Need to replace the panels - see pic. The old one (previous homeowner) is rather heavy and may also absorb sound / pump noise. Not sure where I can get these or just install plywood panels from Home Depot or something? Any ideas would be greatly appreciated. Thanks!

    Solar cover straps disintegrating

    Is this "normal" only after 2 seasons? Did I cut the straps too long? I do not dip these straps in the water and my previous ones lasted years. Also, I store the cover in a bag during the offseason.

    Is my water level too low?

    Had to "repair" rusting skimmer by removing a section of the liner - hence draining the water a bit more than usual. After the repair, I closed the pool and wondeirng whether my water level is too low. Due to rain / snow in NJ, I typically went below the return jet in the past but a few more...

    Removing vinyl liner and repairing skimmer wall

    Not sure this is DIY vs. a pro job but I need to repair the skimmer / metal wall plate(?) behind it as rusting is causing leaks under the vinyl liner (there are a few spots in the deep end and I suspect the rust / water is getting underneath the liner). The rusting was worse and I temporarily...

    Black dust and hopefully not algae....

    Have "black dust" floating on the water - seem very light. Based on my research on this site / internet, a few discoveries: 1. Dust from "BBQ" 2. Black algae - but most, if not all, postings indicate they are at the bottom of pools while mine is floating freely I recently poured in Borax to...

    Deck O Drain Cleaning and Lessons Learned - Use a Shop Vac, too

    Before I begin, I will certain use a snake, a power washer, etc. if / as needed in the future. Also, as a last resort, will consider installing a deck drain janitor (How To Clean Pool Deck Drains | Pool Deck Drain Janitor). Meanwhile, I simply used this method - - using a nozzle / hose. One...

    Backwash vs. Cleaning Filter After Opening (and Some)

    Opened last weekend and the water has been rather "less green" this season (and preemptive winterization balls, floater, sponge, etc worked well). Already almost clear after 2.5 days and backwashed once on my first day when the pressure climbed up to 20 or so. I typically clean out the filter...

    A hole behind the liner?

    Just noticed a "hole" behind the liner when I was closing the pool this season. My PB said this is due to either rain / water and/or an animal digging a hole from behind, and need a repair with pool plaster / formaldehyde before we open the pool. Has anyone experienced something like this (and...

    "No Flow" at Lower RPM of my Hayward Variable Pump

    Recently, I have noticed the infamous "no flow", red indicator being on at lower RPM (been testing, and even at 2800RPM). The indicator goes away when I run my pump at 100% 3450 RPM. I acid-cleaned the cell during the opening, and the sensor wire actually sits "before" the water passes through...

    Fighting Mustard, Black Algae vs. Complete Drain and Clean

    I was fighting with mustard algae for 2 years (no success) before I had to replace my liner due to leakage (beginning of last season). This mustard algae start spreading and had a difficult time controlling even with TFP methods. Also, the algae would disappear above FC 10 or so but return...

    Polaris Volute Leaking / Crack

    Going through 4th volute for my booster pump as the top (where you thread in a quick connect) keeps cracking, causing a leak. I DID NOT use any pipe dope / teflon tape which apparently causes the rounded, top neck to crack, and only used a small amount of magic lube. Did anyone else experience...

    My Zodiac PB4-60 booster pump is in its 3rd year of operation (and since we are in NJ, we use the pool 3-4 months each year) and already developing some leak (around the seal shaft area and/or the bottom of the volute). Ordered both a new volute and a seal kit, just in case. My question is...
