    Preserving test reagents?

    Soooo I accidentally ordered two TF-100 refill kits (not even in the same order. I ordered one set, forgot and ordered another set a few days later). I know reagents “expire”. Is there any way to keep them good until next season? Vacuum seal them in a bag or something?

    Solar (Heliocol) heater vs PV + Heat Pump Heater?

    We're in Northern California and have an 18,000g in-ground that we're currently heating with a somewhat-undersized Heliocol setup on the roof. Since it's undersized, we have to run our variable-speed pump on high for quite a bit of the day for heating (I think I currently run it for ...

    Help troubleshooting bubbles/gurgling pipes

    So, recently, we’ve started noticing gurgling in our rooftop solar return line. I’ve googled a bit and think I have the problem narrowed down, but I was hoping for a second opinion. The gurgling is definitely in the solar return line (it shakes, even). There’s some air in the pump basket, but...

    Tried searching to no avail. Any thoughts on the val-pak "Algae Gun"?

    https://val-pakproducts.com/product/v50-005-algae-gun-water-pressure-cleaning-tool/ Looks like it's just a pressurized nozzle that attaches to your hose and pole. I have trouble imagining it would generate much pressure out of a garden hose. Anyone tried it? Along those same lines, though, any...

    Saddle tee okay for adding temperature probes to my solar lines?

    So, I’m hoping to add some WiFi temperature monitoring with D18B20 temperature probes, but I need a way to get them into my pipes. I could add tees to my lines (then JB weld the sensors into screw caps in the tees), but that will be a pretty major pain. Saddle tees look promising, but I’m...

    Overflow a problem?

    So, in Northern California, we've had quite a bit of rain this winter. My pool (IG, gunite, PebbleTec) has been sitting right at the top of the tile line, water-level-wise, but I haven't seen it draining off or overflowing excess water anywhere. I'm fairly certain we don't have any kind of...

    Well, I didn't listen (kind of), and now I'm regretting it. Stains from Bio-Dex 300?

    I posted recently about calcium scale. It was recommended that I try getting it off with muriatic acid and a scrubber. I did that, and it actually got off a significant portion, but was kind of a pain, so I tried the bio-dex 300 my pool guy left for me. It is basically a few different acids and...

    Scale/calcium at water line - unavoidable?

    Long story short: we had new pebble-tec installed a year ago. Since the fall, we've had a guy taking care of the pool. We've had some algae over the winter (not bad, but some on the tile/grout mostly). Today, I noticed a pretty major calcium line. It turns out auto-fill was off, too. Is this...

    Heliocol installation questions (DIY)

    So, I just picked up seven HC-40 (IIRC. 4'x10.5') panels for a song (friend of a friend just bought a house and didn't like them. Had them tested by a local installer, who said they're in great shape with no leaks). They came with the connection clamps, but it looks like I'm going to need to...

    Splotches/discoloration in newish Pebble Tec?

    So, we had our pebble tec done at the end of May. Since then, it's been fantastic. We had a great summer and probably swam more this summer than the last two years combined. Within the last month or so, though, I've noticed some discoloration in one part of the pool near the shallow end. Here...

    Filter only building pressure when the water feature is on?

    So... pool remodel, new pump (Jandy VS-FHP1.0), new plumbing, new water feature (Paramount Parascope). Finally got the pump up and running yesterday, and it looks like the pressure gauge on the filter only goes up (to about 10ish) when I turn the valve to activate the water feature. Otherwise...

    Offset umbrella in shelf umbrella sleeves?

    So, our remodel is basically done (mostly), and now that we've got water back in the pool, we're taking advantage of our umbrella sleeves. The placement is a little off for getting the shade in just the right spot, but I was thinking today that an offset umbrella could provide a lot more...

    Pebble Tec - too much plaster in the corners?

    So, our pebble tec (tahoe blue) went in yesterday, acid washed today, and we're filling now (soooo slowly). Looking at the corners of our shelf/step, practically all of them have a lot more of the blue plaster showing through than the rest of the surface, which looks kind of crappy IMO. pics...

    Pool refinish... should we replace metal (we think) plumbing while we're at it?

    So, my wife and I bought our house in 2012. It had been vacant for several months prior to that, and the pool was left to rot (it was quite swampy when we moved in). Last year, the plaster on the top step of the tile started flaking off, and there have been major problems with black algae (at...
