Hi, I'm new here I've had an inground 17000 gallon vinyl liner pool since 2008 and still haven't mastered balancing chemicals yet. We bought our house as a foreclosure and had a brand new liner installed. At yr 4 the new liner was falling apart and after contacting the company they sold us another new one at 28m thickness for 75% off and we also had that one professionally installed and some new plywood sides put in behind it because of decay that the original installer didn't mention.
But from day one let me tell you everything always balanced on the pool except chlorine and stabilizer. In the 7 yrs we have had it we've only had to add other chemicals twice and that's because they were trying to figure out our stabilizer problem. Because we have a hard time keeping stabilizer and chlorine in the pool we get algea quite a bit which puts us at purchasing new cartridge filters 2x a yr at 100 bucks a pop. We have the pool places around us completely stumped why we can't keep stabilizer in our pool. Just this yr we opened the pool about 2 months ago, in that time we have had to add 15 pounds of stabilizer (5 lbs each time) because it zeros out. We have had a few pretty hot weekends where it was almost 100 and have had to add maybe 3-4 inches of water in that time frame. Like I said before we have a cartridge filter with a 1hp pool pump we run it 4 hrs in winter a day and summer avg is 6 to 8 hrs a day. We have an auto chlorine tablet feeder that's not in line but connected after the pump and after the filter with little black tubing,and we keep that all the way opened and full of tablets. We generally have to add water a little more than a concrete pool which both pool stores have said is normal for vinyl but they can't figure out why we are having to add 5lbs of stabilizer a month to the pool in warm weather. The last guy who tested our water (Leslie's so they keep record on their computer our last readings and such) said to me there was no possible way unless I completely drained the pool that I could of added 5lbs of stabilizer 2.5 weeks before and it be reading zero today. I'm thinking Yeah I'm lying, I just like to spend 30.00 a month on this stupid chemical that most people have too much of and I'm stock piling it in the garage waiting for a world wide stabilizer shortage.
So anyways I'm not really sure what other info I can give you but is there anyone out there with this issue? Is there a solution because between the cost of electric in my area, tablets, shock, liquid chlorine, stabilizer and new filters I'm ready to get a few truckloads of dirt and fill this stupid pool in! Thanks for any help and suggestions you may have.
