    salt corrosion on above ground pools

    We moved into a house that had an AG pool 5 years ago and I installed a SWG 4 years ago and love it. The pool is 8 years old. This year, the steel top rail had rusted all the way through and I need to replace the pool. After talking to 3 pool supply stores, most of them said they don't carry...

    Pump Preferences??

    I have a 1.5 HP Pentair Dynamo pump that is 5 yrs old and making some noise and tripped the breaker yesterday. If I have to change out my pump, is this a good choice for replacement or can anyone suggest a better one for the money? I see a lot of others in the catalogs such as the Hayward...

    SWG starting chemistry...

    Hi All, Opening the pool tomorrow with my new SWG. In Pool School it mentions to add salt as the first step. Should I balance the water first to make sure everything is in line before turning on the SWG? I know I will need to add quite a bit of CYA since I lost about half my water this winter...

    Aqua Rite SWG start up question

    Which SWG ???

    This will be my second pool season this year and I am seriously considering installing a SWG to keep from having to add bleach every day. Can you recommend which brands of SWG are best considering function, information readout, price, how long the cell lasts, size of pool, etc.? I have heard...

    Hot water...

    Hi All, Having one of the hottest Junes on record here, our pool water temp is now 90 degrees. The only way I know to lower the temp is to drain and refill which would mean starting over with balancing, adding more CYA, etc. Thought of trying to put in some block ice but don't know how well...

    Does CYA have a shelf life?

    Hi All, I recently replaced some water through backwashing, too much rain, etc. My CYA went from 50 to 30 so I wanted to get it back around 40. The pool calculator says for 16,100 gal I needed 22 oz by volume of stabilizer to go from 30 to 40. I got the stabilizer (100% cyanatic acid) at Lowes...

    Testing after adding CYA

    Yesterday I added enough CYA to raise my level from 30 to 40. It was a granular form that I purchased at Lowes. I tried to dissolve it in a bucket of water but soon learned it would not dissolve. Then I remembered reading something on here about putting it in a sock in front of the skimmer so I...

    Cleaner issue or liner problem?

    First time pool owner and opened it about 3 weeks ago. We live close to farm fields and the wind deposits plenty of soil into the pool which is visible on the bottom. Pool was installed in 2007 and came with a Pentair EZ Vac cleaner. Problem is the cleaner will make one or two random passes...

    How long between testing at start up?

    Just got the cover off and replaced about a third of the pool volume overnight. Got the filter running with new sand. How long should I let the water circulate before taking my first set of tests and then how long in between adding whatever is needed before the next tests? I am thinking one turn...

    Very first TF100 test results, need advice

    Pool cover is still on, am opening end of this week but wanted to get a sneak preview of what I might find. I know the previous owner was pool stored so I expected high CYA. Sample was taken under the cover through the skimmer. FC 7.5 (seems way high) CC 0.5 TC 8.0 pH 6.8 TA 40 CH 350...

    Howdy from Missouri!

    Hey everyone, First I just want to say that I was fortunate enough to find this site before I was corrupted by the pool stores. I am a researcher my nature and wanted to learn all I could about pool care on my own. We bought a house this winter that came with a pool and it is my first...

    How much sand do I need?

    Hi All, We bought a house that came with an 27' AG pool. It has a Pentair Meteor sand filter but I am not certain which size it is or how much sand it needs. The label on the filter shows that it is either 18", 20", or 22" but the label indicating the size was not punched out. I do know that...
