Morning all first post so be kind
Well i've been a pool owner for just sort of 2 years, which is when i moved in to the house.
The pool is a outdoor inground 36ft x 16ft hooper style bottom.
Since moving in we have installed a dome cover the type that you can swim under and also slide back when the sun does actually shine? As well as a fastlane swim machine.
Also has the filter sand replaced.
Pool is heated and this year I installed a biomass boiler to keep in nice and swimmable all year (was quite an interesting project)
I've also done alot of work around the pool which is when my troubles started.
In spring last year I had a whole pool area relayed with a stone resin (sometimes called stone carpet) while the builders were doing the work the pool developed a yellow coating to the base of the pool, I assumed this to just the dust from the sand they were using, anyway I hoovered the stuff away and within a few weeks the pool was clean and clear, periodically i would find small areas of what i thought to be sand accumulate on the seam of my pool liner and in a low circulation area. i would hoover it way each week, this stuff was so fine and dust like when yo disturbed it with swimming it was hardly noticeable.
I kept the pool open throughout the winter but without any heat, (as Triathlete wetsuit swimming suits me!)
All things where going great with the pool in early spring then one week I returned home from working away for a few days to find the pool looking yellow, on inspection the water water clear but this dust like substance had returned to the bottom of the pool fully covering the bottom, mixing the water up just made it milky and cloudy but the residue would settle within 24hours and form the same layer of yellow ish dust. after many different chemicals i eventually had to vac to waste to get rid of it wasting a lot of water. I vac'd to waste every night for a week. That was in June, now in September the stuff has started returning, i noticed a small amount and vac'd to waste about 3 weeks ago, it then returned within a week, now it's returning overnight. I shocked the pool Monday to see if it would work but nothing.
Yes I've rambled on to long and probably not covered any of the basic you need to help but I've got photo's
