Hello to all,
I am new to this forum so bare with me while I get up to speed. I have an 18x36 in ground vinyl liner pool which has had a problem from last season,and is still an issue this season. There is a grayish dust that collects every few days in all the crevices and seams in the liner. Shallow and deep end both have it. I can put the brush to it and it dissipates in a cloud of dust. I have shocked and brushed the pool too many times to count,vacuuming to waste the next morning,only to have it come back in a few days time. It is not yellow or green in color.It is more gray than black.
The other issue I have had since this began is that I cannot keep chlorine in the pool. The FC reading has been zero since I opened it up this year.Yesterday,I nuked it with 8 lbs of CH Shock.Today I have a free chlorine reading as posted below. I have no confidence that it will hold. Something is eating the chlorine out of this pool besides the heat(100-105 daily) . Just my opinion. I have heard that it was dust,dirt,brown algae,black algae,and numerous other things.The local talent here do nothing more than make my head hurt and cost me money.I also was gullible enough to treat for each of these things,at a substantial cost. I have had enough. The last guy I went to see told me it must be a bacteria in the water,which he had no way to test for,and I should double the shock dosage yesterday,and triple it today. Obviously,they are in the business of separating me from my cash,not trying to clear up my issue.
I have tried to post some pics of what the stuff looks like,but the BB says the files are too big. Will gladly email them to anyone who wants them. Have posted test results from this morning. I use a taylor K2005 test kit and a seven way test strip. I believe the test strips are highly inaccurate ,but until I can get some more R0013 reagent from Taylor, it is the only means of a CYA test I have. Pool supply stores do not carry that reagent. I have locked the water up twice in the last 5-6 years due to over-stabilization,so I watch the CYA closely. Any help anyone can offer will be greatly appreciated.
