    Turquoise & rust grit in spa & heater problems

    We opened our pool for the season on 4/13/2024 (just over 3 weeks ago). It took a few days to clean/vacuum/filter out the silt and get the water chemistry back in balance. On first use of the spa, we noticed the plaster felt rough (I posted about this in a separate thread). I haven't had a...

    Rough plaster upon opening pool (second Spring opening)

    We opened our pool 5 days ago, cleaned it up (mesh safety cover, so there was a lot of dust/silt to remove), and balanced the water. First time in the spa last night, we realized we had rough plaster. UGH! The roughness is mostly on the horizontal surfaces (benches and steps); not so much on...

    Pre-closing water chemistry questions

    We're scheduled to have our inground plaster pool closed & covered (mesh) in 6 days. I am to have the pool clean and the water balanced, and I'll be adding Polyquat 60, so that the service won't be adding any chemicals. Here are my latest test results: FC 8.0 pH 7.8 TA 90 CH 325 CYA 80-90 (I...

    Hayward VS pump -- FREEZE PROTECTION

    This is our first season with the Hayward Omni Logic controlling the pump, chlorinator, etc... and it seems I no longer have control at the actual pump keypad. Tonight our pump "Freeze Protection" kicked on at 39 degrees. That's fine but the pump is running at 100% speed (3300 RPM, I think)...

    Broken Copper Bond wire

    In the course of a pool deck remodel, a strip of concrete deck was removed & one of the four copper bond wires were broken. Each end is fairly easily accessible to "splice" them back together. I'm looking for the best/approved/safest/ permanent way to do that. I may also have access to a...

    Best coping-to-concrete deck gap sealant

    Our pool has been "Under Construction" since March 2022. One thing that was never done by the GC was applying sealant to the joint between the concrete deck & Travertine coping. It cause a lot of Travertine damage over winter 2022/2023. We're going to get it all buttoned by a remodeling...

    leveling the pool

    Hello- I hope this is the appropriate place for this topic: Our gunite pool was started in March, 2022, plastered & filled with water in September, 2022. Concrete deck was poured August, 2022. Pool was "Loop-Loc" covered in November, 2022... Over the 2022/2023 winter (Tulsa, OK), our...

    AquaBond AquaFlex sealant - Anyone Use?

    A similar question was asked in 2017, but got no responses for this particular product, so I thought I'd ask again. We have a leak in our gunite spa and are searching for the best product to use to repair it. This product looks promising. Anyone used it? Have any comments? Any other product...

    Leak in gunite pool - spa inlet

    We have a new gunite build, pool/attached spa. A bucket test verified that we have a leak, and a dye test revealed the leak is in the spa at one of the inlet jets (about 300 gallons per day). Looks like the leak is at the joint between the plaster and the plastic flange/socket of the inlet...

    Advice on balancing chemicals after wind event

    Last night, we had a pretty bad wind event resulting in lots of leaves, twigs, dirt, etc. in the pool this morning. We've got it cleaned out and the robot vacuum is running for the second time today. We also lost power for 5-6 hours, and then I had the pump off until I got the big junk out of...

    How to plug everything for leak detection

    Our bucket tests show we have a leak. We don't see any leaks at the equipment pad, so the next step according to the How To - Leak Detection article is to "plug all the inlets and outlets (returns, skimmers, drains, cleaner lines)". For our two skimmers (which have 2 holes in each), are...

    Evaporation Spreadsheet still available? Concerned about potential leak.

    I've read up on using the Bucket Test to check for leaks, and I'm planning to try that starting tonight (weather permitting). In the meantime, I wasn't able to open the link to the Evaporation Spreadsheet in the following article. Is that spreadsheet still available? If so, can someone please...

    CH is low -- What product should I add to increase it?

    This is my first season with our pool, and I'm finally getting the hang of the chemistry. Here are my TF-100 results from this morning: FC = 12.5 CC = 0 pH = 7.8 TA = 90 CH = 212.5 (needed 8 or 9 drops; I couldn't tell exactly) CYA = 80 water temp = 85F Salt = 2900 CSI = -0.12 CH has been...

    No change in pump pressure after cleaning Hayward cartridge filters

    First time cleaning our Hayward cartridge filters today. Pool is basically a new build (we only used it for 2 days last Fall before having it closed for the winter, and it has only been opened about 6 weeks thus far this season). I've been keeping my eye on the filter pressure gauge. I...

    Pump speeds & run times with SWCG

    Our pool/spa was mostly completed last November, then closed for winter, and re-opened about 2 weeks ago. I'm pretty confident in my ability to perform the chemical tests (now that I have my handy-dandy TF-100 Pro with Salt... with Smart Stir, which could be called "the marriage saver" ;))...

    Sharing my pool info on Pool Math App and other App Questions

    Newbie here! I want to get set up properly on the Pool Math app, and some of the choices I don't understand... #1 - Tapping the upload(?) symbol at the upper right (just to the left of the Settings symbol), I get to the question, "Which pool information would you like to share"? I would like...

    TA Testing Question re: turning red

    Hello. So grateful for all the generous knowledge-sharing here! I have a question about TA testing... I'm using (for now) a Taylor K-1004 Test Kit. When I add & swirl drops to get the number of drops until the green "turns red", what does that mean? As I swirl, I see a bit of red which then...
