Looks like I have my first instance of calcium scale. I had to SLAM the pool and have maintained high chlorine levels, so I haven’t been able to test PH. I just tested and my Alkalinity is 110, so likely the culprit here where it has a slow leak from my fountains. Best bet to do an...

Hey all! Been a long time follower here and utilize all the resources, including Pool Math. My main question is: On a Hayward T-15 Salt Cell, all the numbers on the panel look good and readings are correct, but is there another physical way to test to see if the salt cell is producing...

Hey All! I am getting a new roof on Monday and having a solar company rip down my existing, 6 panel, west facing solar panels. These panels were approximately 300-400ft away from the pool pump. The technician just made a suggestion that for another ~$500, he would recommend adding 2 panels...

Hey guys, My dad busted a pin on the IntelliFlo VS pump that connects to the solar panel. Any idea where we could purchase this cable? Or should we try to re-terminate the pin, even though I have no idea where to procure the pins themselves?

Hi there! would any experts be able to review my pool math and advise why folks would be complaining about itchy skin in my pool? I thought everything looked perfect? Maybe a tad bit too high Chlorine?

Hey guys! So since I had so much success with my TF-100 and TFP method, I’ve been excited to test all my family members pools... which is probably a mistake. just curious, my in laws pool is all out of whack with results! But they have maintained this pool for 20 years and only ever have to...

After reading through the forums and articles posted, I would like some guidance. would I be better off running my VS pump at near max (3000 RPM) for 4 hours with my SWG at 100% to produce enough chlorine vs running my VS pump at lower (near 1700 RPM) for 8 hours with my SWG at 50%. Pool is...

Hey guy, I have solar panels with an automated switch. I notice that when my solar is OFF, I get a leak from the vacuum relief valve. Slow drip. What is interesting is it changes based on RPMs from the pump. When priming and running high RPM, no leak. Once it is done priming and runs down to...

Is there a way, without taking the filter cartridge out, to know what cartridge to buy? I see three model numbers on the outside...

I assume this is bad? I turned off the breaker to clean and look for algae and the fixture is full of water. in the process of taking it apart. Am I going to need a new light fixture and run new wires?

Just curious, if I were to SLAM and get my FC levels to 28. Then proved OCLT passes and I turn my SWG to produce roughly 4-5PPM to account for the sun loss. Would/should my FC stay at 28 indefinitely (assuming no algae, etc) or is that level just too high for the sun and CYA levels?

Hey guys, My salt system (cell is 3 years old) is continually stated 2600 - 2700 PPM of salt, whereas my Taylor kit and pool store both confirmed a 3200 PPM of salt in the pool. My next step is going to be to try and clean the salt cell. My question is, how much build up is too much? For...

Hi all! Long story short.. pump died and I ended up installing my own and firing my pool service. During the two weeks the pump died, pool slowly turned green. Ran the pump for 48hours and SWG on super chlorinate. I thought I was good to go after cleaning the cartridge filter and pool was...

Got her today! Curious how many store them upside down like manual says?

Hey all! This forum has been awesome so far and gave me the courage needed to dump my pool boy. Finally received my TF-100 Pro today and ordered and E30 robot cleaner. I’m also glad I reviewed in depth, as my salt cell generator has been screaming 2500 PPM but I actually measured 3800 PPM...

Hey guys! New pool owner and have been using a pool service for about a year now. After having to install my own pump and research a ton, I’m planning on giving the pool service the boot and doing this myself. 14k Gallon pool, screen enclosure, Florida, Hayward SWG and Tristar 900. Pool also...

You guys have been a tremendous help, thank you! I just successfully installed my new Hayward Tristar 900 and the pool is up and running. I now have some questions on air bubbles. I was advised that air bubbles in the pump lid are not good for the system.. true? I have a solar system that I...

Just installed the Tristar 900! seems like they changed the speed buttons on the left hand side. You can no longer program their run time and they just run until the next preset timer? Can any one confirm I am not missing a setting? wonder why they implemented this change!

Installing new Hayward Tristan 900 to an intermatic timer. The red and black are connected to slots 1 and 3 in the timer as line and always on. does it matter if red or black are swapped at the pump side? L1 or L2? Images attached.

New pool owner. 15k gallon pool. Hayward Ecostar 2.75HP just died. I do have solar panels on a single story home. Is a certain HP needed to get the head needed to reach the roof? Other things I should look into before purchasing an alternative pump? thanks!

Hey guys! I have recently ordered a new Pentair Intelliflo VSP and an IC40 to replace my existing Hayward system (pump died). Install is next week. However, I have read a lot of great things about the Circupool brand. Is it purely preference or does any one have history with both and pros/cons...

Hi guys! New here and would love to hear some thoughts from you experts. Have had my house with a SWG pool for just over a year now and have been using a pool service. Pool is approximately 15K gallons (to my best guess - image below). Currently use a Hayward Aquarite with a TCELL940 for the...
