I have decided to try a no drain acid wash to try and remove some stains i have in a plaster pool. The pool is approx 22,000 gal. Yesterday I added 10 gals of muriatic acid to kill the alkalinity and drop the ph. The question I have is: Assuming I have success with removing the stains, I...

After speaking to tech help @Hayward, they have advised me that my control board for my Max Flo VS (model# SP2300VSP) needs a new control board. Naturally I asked the person I was speaking to @ Hayward about purchasing that part. He told me they dont sell parts to the consumer and to contact...

First of many thanks to this forum and how its been extremely helpful. 4 years ago I had a 15k gal fiberglass pool installed. Using the liquid bleach everyday and a little muriatic acid once in a while I never seem to have to add anything else. The only time I've ever shocked is each spring...

Is it possible to purchase a waterproof cable swivel seperately and slice it into you robotic pool cleaners existing floating cable? If so does anyone know if/where one can purchase this type of swivel? I am happy with my current robotic cleaner but I hate untangling the cord so often.

I was wondering how directly chlorine usage is responsible for the ph rise in pool water. I am wondering if there is a way to quantify it, if it is. My thinking is... Would it be possible to add HCl (very dilute HCl I imagine) to my chlorine holding tank on my stenner chlorine feed system.

I noticed that there are several choices for replacement cartridge filter elements (pleatco, unicell,filber,etc.) Does anyone have any info as to which brand (if any) use the lowest micron rating? Does any manufacturer have anything down around the 5 micron rating?

Is CYA more soluable at higher water temps? Does anyone know how soluable CYA is?... Is it possible to dissolve several pounds of granules into a 5 gal pail of hot water and create a super sat solution of it? Then keep it stored until needed.

I recently completed a stenner pump project and am trying to fine tune it. Every day for the past couple weeks I've been checking my chlorine level with a FAS -DPD test ( using the 25ml sample and multiply drops by .2 to be as accurate as I can) Doesn't seem to be much rhyme or reason to it...

I was hoping to get a salt water chlorine generator and install it this spring until I started reading this forum. Then I decided to go with a stenner chlorine dosing system for several reasons: -costs less than than a swcg ( no salt cell to replacein 3-5 years) -dont need to add salt and...

After receiving a lot of rain the water level in my inground pool is a high ( above the skimmer opening) . I know most folks with sand filters have a waste line they can pump off the excess. I happen to have a cartridge filter. I was thinking it would be easy to remove the drain plug located...

Will liquid chlorine sitting in a storage tank that is 12.5 % strength weaken/degrade at a faster rate than 12.5% diluted to 6 or 8%?

The heater is less than 1 year old and just started making a whistling noise when heating. I did some research and thought it may be caused by a faulty unitherm govenor. I removed the unitherm govenor and the heater ran silently. I purchased and installed a new unitherm govenor and the...

..Not sure if this is possible/practical.. At my place of work we have a X-ray fluorescence unit. We use it mainly for testing the thickness of various electroplated deposits. We also have a small vial which we can fill with plating sol'n... x-ray it, and it will give us the concentration of...

I was able to locate a tank from a water softener system in the trash. It is the brine (softening salt + water) tank. I am thinking of using it for a stenner chlorination project. It appears to be around 30-40 gal in size and has a nice large removable lid. Anyone see any problems using this...

Last fall I had a fiberglass pool installed .. I got to swim in it twice before it was closed. I had the people who installed the pool open it on May 9th. after they shocked it, I waited 24hrs. and tested with a taylor test kit. Cl is 5ppm; Ph 7.5; CYA 10 ( added a little stabilizer and need...

Just recently had an fiberglass IG pool installed. Next spring I'm considering installing a SWCG; the question I have is what systems will produce chlorine at low flow rates? I have a variable speed pump (Maxflo VS) and like to run the pump at low speed (1000-1200rpm) for long periods of time...

In early Sept this year, I had a fiberglass inground pool installed. I'm located in western new york and was wondering if I can just put the safety cover on and let the filter pump run on low speed just to slowly keep the water moving all winter long, instead blowing out and plugging the lines...

About to have a fiberglass 15k gal pool installed. Of the most popular(hayward,jandy,pentair,sta-rite,raypac,etc) heaters available which seems to be the most durable and problem free? The heater will also be located outdoors so one that is a bit more resistant to sun fade/weather would be a...
