I seem to have an infestation of water striders -- in the past there were always a couple but now there are a bunch. Water temp is still about 75 degrees, chlorine level is 3-5, water is crystal clear. pH is 7.6. A small amount of algae forms under the skimmer after a couple of days, easily...

Have a 26,000 gallon salt water pool. After a storm and a bunch of rain, the ph was over 8 so I added muriatic acid two days ago and got the pH down to 7.4, which is where I keep it. Today, I decided to descale the chlorine generator with the acid bath and afterwards, I dumped the acid bath...

My pool has two skimmers and two main drains. The skimmers have two holes in the bottom, and the hole closest to the pool has a flap and seems to lead to a nearby inlet under the water line. From searching TFP, I gather that this is an "equalizer" to guarantee water flow to the pump inlet if...

I have a Jandy Aquapure PLC-1400 chlorine generator system, and I'm puzzled by the salt level readings I've been getting. Before I added salt (see below), the SWG display reported the salt level is 3,000ppm. It was 3300ppm, which is about where I normally keep it, but then we finally got a a...

I have a 2-1/2 year old Dolphin S-200 that replaced a Polaris pressure-side cleaner. It's been working flawlessly until now and my pool has literally never been so clean. A few days ago, I noticed if I push the button to start it, the blue light on the front flashes, it starts cleaning for...

I have a pool slide where the tiles have been damaged by the two big Texas freezes over the last two years -- guessing water got underneath the tile and lifted it, causing a hunk to fall off and cracks to appear. I contacted one pool remodeling company to come out and bid and they want $9,000...

I upgraded to VSP pumps this past summer and am now programming the freeze protection. I'd just like to confirm that it's safe to run the pumps at a low speed. The goal is to save power and not annoy the neighbors if we have another Texas freeze like last year when they have to run for days on...

We have four Jandy 120V color-changing lights with burned-out bulbs that I'm having replaced with Jandy Watercolor LED lights. Three of the swaps went well, but the fourth large light is a good distance from the box. It appears the electrician that installed it back in 2006 did something goofy...

I have a 26,000 gallon salt water pool, Jandy PLC-1400 salt cell, and keep the salt level at about 3000ppm. I normally keep the SWG set to 75% and that gets me a total chlorine level of 3-5. However, several months ago, I replaced the Jandy stealth pump with a Jandy e-Pump and a Jandy sand...

My pool, built in 2006, has 4 Jandy color-changing 120V halogen lights: two big ones and two little ones (one in the spa). We didn't notice this until a few years ago, but the two large lights are in niches that were installed cockeyed when the pool was built, so the screw receivers are at...

Merged several threads into one. TFP Mod. I came here to ask almost exactly the same question as in a previous thread, but don't want to hijack that thread. So here goes... I have a 26,000 gallon SW pool/spa with two Jandy Stealth pumps, one for the pool filtering/spa and one for the water...

Thanks to recommendations here, I replaced my aged Polaris 280 with a Dolphin robot. It's fantastic, and a great improvement -- no looking back. Now another, admittedly smaller problem: my pool guy has been AWOL since April. That hasn't been a problem because I pay per weekly visit, and with...

I'm thinking about switching to a robot from a Polaris 280, which just lost a wheel and is spinning in circles. Is it really necessary to cap off the lines and remove the booster pump? Seems like I could just program the Polaris pump to never come on except when it's in "freeze protect mode"...

Recently during the freezes in Austin, I could hear my pool pump occasionally make a real racket. I discovered this was because the freeze protection was switching between pool and spa mode a couple of times an hour, and the instead of the valve handles rotating 180 degrees, they just went all...

Our spa is pretty far from our equipment, so we have a spa blower that sits on top of a pipe -- it looks like the current Polaris QT blower, 240V 2A, plastic case. Back in 2007 or so, pool water backed up into it (yikes), so the maintenance guy elevated it, but it's never worked properly...

I have a Laars LT heater (2006 vintage) that we only use a couple of times a month to heat the spa. A couple of weeks ago I noticed that, while heating, it was shutting off prematurely -- the first time when it reached 98 degrees, and the second time it reached the target 101 but wouldn't turn...

The motor in my filter pump failed last week and I need to replace it. I figured this was a good time to switch from a single speed pump (a Jandy JHP 2.0) to a variable speed pump -- partially to save energy, and partially to reduce the noise, especially when the system goes into freeze mode...

Howdy! We have a two year-old 26,000 gallon salt water pool with Jandy equipment and "pacific blue" plaster. Last summer, we started seeing little hard white spots scattered around the bottom, interspersed with just a few larger ones. The bigger ones look kind of like bird droppings, the...
