Patrick, Thank you. I spent another few hours today with calls and internet searches. From the reviews I have read none of the robotic cleaners will do steps or benches so I will leave this issue out of the equation. I read below the comment that the water line is dealt with intermittently...

I purchased a home last year with an in-ground pool. See my pool profile information. I have spent probably 5 hours online reading reviews. Too much of what is now on Google are simply advertisements, and of course are biased. Here's a synopsis of my pool cleaning "history": 1. House came...

I bought a house with an 18K in-ground pool, (see signature re full info). The Polaris 380 that the prior owner had worked after a lot of adjustments by me but now it is a problem, which I will not go into right now. My reviews of robotic cleaners has me just about to buy the Triton Plus along...

I have an 18,000 gallon in-ground pool, with propane gas heater + passive solar heater, pentair sand filter. I am the 2nd owner and the original owner never tested for cyanuric acid (CYA). Despite levels of CYA > 500 the pool was crystal clear and free chlorine was adjusted by me using liquid...

Thanks for the replies above. I did do many Pubmed searches but CYA is almost always not part of the title. I just performed the same search with cyanuric acid being mentioned in the abstract and found 402 papers between the years 2000 and 2014. I just finished scanning the titles of these...

I am new to this forum. As a physician-scientist I feel it is imperative to try to understand biological mechanisms and relationships as much as humanly possible. I recently purchased a home with an in-ground pool. The stats re the pool are shown in my signature. As an aside I had a formal...

Thanks RobbieH. With what you have said, let me ask further questions. Given my high CA levels and plans to exchange water with well water that has "low" CH, and assuming that this diluting process brings both CA and CH down to acceptable levels, what downside do you see to CalHypo given that...

I have always loved chemistry so the issue of pool chemistry is actually fun for me; but I will have to relearn stuff from many years ago. I just "inherited" a pool in the house we purchased where the original owner scoffed at the finding of very high cyanuric acid levels (> 300 with 50:50...

Casey, I am new to this forum and certainly a far cry from a pool expert, but I have some questions regarding your advice above. Rain6460 (Rain for short) is using liquid chlorine after being traumatized by the high cyanuric acid levels containing Dichlor or Trichlor. My understanding is that...

Thanks Tim. I can Google Stenner pump or have you share with me key info about this. If this is a device to add liquid chlorine, which I assume it is, please feel free to share. What is surprising to me is that all the granular and tablet chlorine that contains stabilizers that are...

Richard, thanks for the quick reply. I am now highly skeptical of the honesty and integrity of those "serving" the customer in my area. My inclination, along with what you have said, is to do it myself. I did initially purchase the aquacheck 7 test strips made by HACH and am keeping a log...

Just bought a new house with an in-ground pool that is at least 12 years old. It is chlorinated, uses a Polaris 380 as pool cleaner, has a Pentair Meteor Sand filter, propane gas heater and solar heater. The pool contains about 18,000 gallons of water. I have had 2 pool serviceman. The first...
