Best VS Pump for 110 Volt Equipment Pad
Back in the day if you had a 110/115V set up for your pool equipment there was no way to upgrade to a VS pump. Pentair broke into the 110V equipment pad market with their SuperFlo Vs which is a sold pump but lacking in a few areas. The Jacuzzi JVS165S is a fully functional VS pump designed with dual voltage so it will work with either 110/220V breakers.
Some features that make this the superior 110V pump to upgrade to is the extended 3-year total warranty if the pump is purchased at Leslie's and installed by either Leslie's or a Leslie's Pro Partner.
It is also automation-ready and can work with any of the three major brand automation including Hayward, Pentair, and Jandy. One thing the Pentair Superflo VS cannot do is connect to existing automation, but the JVS 165S is perfect for any automated system. It is also made right here in the USA.
The easy to program control panel and the advanced Time Out mode set this pump apart from others in this category. Setting up and programming this pump could not be easier. This pump also features one of the best DOE (Department of Energy) ratings meaning it is extremely energy efficient - a 10.7 WEF rating!

The Problem with High CYA in Your Swimming Pool
One of the most common water balancing issues is having high Cyanuric Acid (CYA) in your pool. Cyanuric Acid often referred to as Conditioner or Stabilizer is added to the pool in order to slow the chlorine burn-off caused by the Sun's UV rays. But if you use 3” Chlorine Tablets (Trichlor Tablets) you will be adding Cyanuric Acid to your pool on a constant basis. Here I will discuss the effects of high CYA in your pool water, how to correct it, and ways to prevent it from rising to high levels again.
Bob Lowry is the author of over 23 books but this has to be one of his most relevant and shortest books coming in at just 19 pages thick. But it is packed with so many essentials on residential pool chemistry that you will want a copy to carry in your service truck. Bob Lowry has been in the industry for over 47 years and is the Lead Consultant at Lowry Consulting Group, leads the Pool Chemistry Training Institute, and has created the Certified Residential Pool & Spa Certification Program.

If your CYA level is very low the Sun's UV rays will cause the chlorine to burn off quickly leaving your pool with no sanitizer or very low levels. The Conditioner in the pool helps to protect the chlorine from burning off too quickly.
Very high CYA levels will make the chlorine in your pool less effective which means you will have to keep the levels very high in your pool to make it effective. Your pool may also develop algae blooms even with high chlorine levels present. These algae blooms are also hard to get rid of in a pool with very high CYA levels. High levels of CYA will also give you false ORP readings if your pool uses ORP to measure the safety and swim-ability of the water. High CYA also will give you a false Alkalinity reading, if you test the Alkalinity and it is at 100 it is more likely at only 70 if you use the Adjusted Alkalinity reading,
The ideal level of CYA in your pool is 30-50 ppm and up to 80 ppm of you have a saltwater pool. Testing the Cyanuric Acid level in your pool at the beginning of the season is crucial. There are many ways to test the CYA level in your pool including the standard Turbidity test, digital testing, and test strips.
You should also utilize the LSI Index (Langelier Saturation Index) in your pool water testing. This will let you know if the pool water is scale-forming or corrosive. If you have a Taylor Test Kit (K2000 Series) it will have the Watergram included which will help you calculate the pool’s LSI. You can also use several online apps to calculate the pool’s LSI. Regardless of what you use, you should be checking the LSI at least once a month in your pool or the pool’s service.
Testing the CYA level in your pool if you suspect very high levels can be challenging. The standard Turbidity Test Kits only work effectively to 100 ppm. If you get an initial reading over 100 ppm you will have to do a dilution test of 50% tap water and 50% pool water. If the reading is still high you will need to use 75% tab water and 25% pool water and so on. Each time you dilute the sample the reading becomes more difficult to nail down accurately. Test strips are a great alternative in pools that have high CYA levels. Most test strips will go as high as 250-300 ppm so this is a good way to check pools that have very high CYA levels.
LaMotte actually makes a test strip that will read CYA levels up to 500 ppm accurately. This is a very handy test strip to have if you service pools for a living. Just dip the test strip in and then match it up to the side of the tube where there is a color chart.
Since Cyanuric Acid does not naturally leave the pool water if you add it to your pool through the use of 3” Chlorinating Tablets the levels will constantly rise. These 3” Trichlor Tablets are over 50% Conditioner per tablet by weight, so as you use them in the Summer you are constantly adding Cyanuric Acid to your pool water. The only way Cyanuric Acid leaves the pool water is through backwashing and splash out. As the water evaporates the Cyanuric Acid will remain in the pool. To lower the CYA level in your pool you will have to do a partial or full drain of the pool water.

Oakton CTSTestr™ 50C Cup-Style Waterproof Pocket Conductivity/TDS/Salinity Tester
Oakton CTSTestr™ 50C Cup-Style Waterproof Pocket Conductivity/TDS/Salinity Tester, Premium 50 Series is an underrated digital water tester. It seems to be a branded tester from Eutech which is an Australian company that makes some of the best digital testers out there. One of the key features of this tester is how easy it is to calibrate and how stable it is.
Oakton – Item # EW-35634-65
Reliable 3-in-1 tool measures conductivity, TDS, and salinity
Redesigned leakproof cap functions as a sample cup and stabilizing base to stand the meter upright
Automatic temperature compensation ensures accurate reading in varying environments
Easy-to-navigate interface for quick setup and calibration
INCLUDES
Protective plastic storage case, lanyard, and 4 AAA batteries.
MORE ABOUT THIS ITEM
These CTS testers make measuring water quality easier and faster. The large display offers a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time. The testers are available in a pin-type or a cup style measuring sensor and measure conductivity, TDS, and salinity all in one instrument.
To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used—no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. The wider design provides a base to keep the meter upright for hands-free measurements. The keypad features a fourth key to simplify menu navigation while keeping convenient one-touch calibration. The housing is compatible with lanyards to prevent losing or dropping but is still waterproof.
I mention easy calibration because sometimes getting these digital salinity meters to read the correct salt level can be a challenge. Oakton makes it easy with this tester by allowing you to plus or minus the salinity reading to match the calibration solution. But calibrating the device is something you don’t need to do often because this is a very stable tester.
It is a bonus that this tester also does TDS (Total Dissolved Solids. TDS is basically all of the stuff left behind when pure water evaporates. If you are wondering how to get an accurate TDS reading in a salt pool the equation is pretty simple. Take a Salinity reading. Takes a TDS reading. Subtract the Salinity from the TDS reading. Take a tap water TDS reading. Salinity – TDS = X.
X – Tapwater reading = TDS.
Example: Salinity is 3200 ppm. TDS reading is 4500 ppm. True TDS is 1300 ppm. Tab Water has a TDS of 300 ppm. The total TDS of the pool is 1000 ppm
All in all, this is a great tester made by a solid company in Oakton.
Leslie’s Pro store also has these in stock.
