Thanks for the info on where made,I was starting to get a little worried and was going to make a phone call to find out.
Only thing I can think of,if the over chlorination was in fact the problem,or just a quick way out for them since the liner was bleached out around the return fitting about 2-3 inches after a combined 8 useage months, they assumed that and went no further.
The pool store is one of only 2 Authorized dealers in the state that I can find,and with Doughboy being almost impossible to buy parts or anything else without going through a dealer,I thought they knew what products are fine with Doughboy liner.
A little background on what the salesman instructed me to do when he was on site after install on Aug 2012.
I was instructed ,after he added stabilizer,to add 2 bioguard silk sticks to the skimmer each week,add proper amount of Algea preventer each week and shock pool with a pound of the bioguard product ea. week.And use the test strips I was provided.
No problem, new pool owner,I got this
So Aug -Sept.2012 did all that,then winterized and covered filter,heater and pool.Was told filter could stay outdoors.
April 2013 -Sept 2013,repeated the above process every week,except bring sand filter into the garage in the fall.I did have my Taylor kit in July and it was testing stabilizer level around 90-100 ppm by then thanks to the silk sticks so I was keeping FC around 8 or 9ppm
Nov- through the winter,found the pool calc.and a FC to CYA level chart and other reference items.
March 2014,after winter thaw, major seam leak.
Maybe what I was sold and told to do,in fact done me in.
Looking back at the silk sticks, what an un regulated way to sanitize,ea day it could go anywhere.
Also, was told by the end of week most of the sticks would be dissolved, and if not some may still be left but just toss 2 more in there.
So, I guess ea week I was pounding the pool into the ground and thinking I was on top of my maintenence.
Pool was only used by 2 of us a couple times a week most of the time,ocassional pool party.
I have been useing the bleach,8% and chlorine 12%-Muriatic acid-Borax since new liner install, never needed baking soda since my tap water is 380 TA.
In your opinion,would TA at 130ppm and CYA at 50 with FC at 6 be fine?
or should I go lower on both?
Just a little nervouse on what next spring will be like.
Also ,I was adding the bleach/chlorine into the skimmer for a couple months this year but got worried about the possible liner fade at the return, so I started to add that in front of the return water stream.
Thanks again for all the help.
