    AGP DIY Disaster?

    I doubt you can fix that without draining. Leveling is something you have to get right before putting water in. IMO leveling is by a huge margin the single most important thing to get right with an AGP. Get it wrong and it’ll be hard for anything else to be good. One thing you can probably...

    Pad under steps

    I have that pad and I cut it to be just under the steps, because otherwise my 'robotic' vacuum gets stuck on it. I don't worry about algae growth much because I keep my chlorine levels on the high end, and I don't let it drop in the winter.

    Bulge in liner right on upright

    Yes. After the wall is bolted together, typically a strip or two of duct tape is run over the bolt heads on the inside before installing the liner. It's 100% normal to be able to see and feel the bolt heads, but the tape ensures no sharp edges will damage the liner. If you can feel the bolt...

    Anybody build their own temperature management system?

    I did a DIY pool controller because it was the simplest way to get the integration I wanted with the equipment I have and the home automation software I use (Home Assistant). But what I don't have is heater control. I wonder, has anyone here built their own setup for controlling a heater...

    Glutton For Punishment Build.

    That looks great! Love to see that TFP-clear water in the end. I totally understand how much the digging sucks. We thought "no big deal, it's mostly level, we can do this by hand" and then proceeded to cart away a few yards of dirt one wheelbarrow at a time. Definitely the hardest part of...

    Guidance sought about a new pump

    It could just be that VSPs are like that, but it suggests a big divergence between pump RPM and flow. My 2-speed pump has a 3x jump in power (measured with a current transformer) for a 2x RPM increase, nothing even approaching 10x. And my RPM corresponds closely to flow -- I get 16 GPM at 1725...

    Guidance sought about a new pump

    I'm skeptical that 1550 to 3450 RPM is 7x the power consumption (more typically, 3x the power for 2x the RPM is in the right ballpark). Or that the runtimes are going to be the same. The VSP will be more efficient per GPM, yes, but you run longer to compensate for the lower flow. You will...

    Calcium precipitate from SWG?

    Thanks for the tip on the CH. My target in PoolMath is pretty high, I'll dial it down. And come to think of it, I wasn't really adding CH early on, because I was unsure if I should put any at all in a hot tub. So the timing makes sense. I can easily dump a bunch of water and fill it again...

    Calcium precipitate from SWG?

    I have a fairly new (less than a year) Nordic Retreat MS hot tub. At the time I bought it, I also bought a Saltron Mini and I've been using that since day 1. A couple months ago I noticed some white sandy particles in the bottom of the hot tub (at each seat, like they're coming out of the...

    Retrofit wifi? Nordic hot tub (balboa)

    I've got a Nordic Retreat MS, bit less than a year old. Under the covers it has a Balboa 55887-04 controller (aka NORVS300). Are there any reasonable options to make this work with WiFi without getting an entirely new spa pack? I see that Balboa makes a WiFi module (p/n 51159) but I'm not at...

    Advice on hard plumbing

    25 feet is fine. That's about how far my equipment pad is from my pool, and I have no problems. 1.5 inch PVC, buried in the ground. Regular above ground pump, 1.5hp two-speed, I see about 16 gpm on low speed and 36 gpm on high speed.

    Salt water generator/which one?

    I've left it in, I've taken it out, I've had it out when it wanted to start a new daily cycle. So far, it's been perfectly fine. It just alternates -- with the hour count if it tries to start while the cell is in the basket, as soon as I put it back in the water it begins generating. If it's...

    Salt water generator/which one?

    Sure is nice to have a fresh new tub of water, after watching what ahhsome cleans out. I've got incredibly soft water, so I've been adding calcium to get up to ~450ppm. Just for anti-foaming. Maybe not really necessary, but I've had foaming in the past so I figured why not. Hopefully it's...

    My TF-Pro Test Kit review + Results

    Thread's getting kinda old, but I thought I'd add my only bit of feedback on the TF-Pro Salt kit. I'd love a version of the waterproof laminated card that included the salt test instructions. I don't test it too often, but I have to go find the TFP page for it every time. Otherwise I'm...

    Is anyone else having trouble finding 31.45% muriatic acid?

    I had a little trouble finding some locally (Portland area) but last week it was back in stock. I may get the green stuff next time just because it’s weaker. My new hot tub is only 250 gal so the full strength acid has to be measured very carefully.
