Greeting, all. I am the lucky owner of a 17 x 35 Grecian styled vinyl liner in ground that was built at the bottom of a terraced hill close to a forest, septic tank, and river As such, it has features I presume are directly related (sump, perimeter drainage, etc.)
Pool service guys, who I now understand may be evil, took the winter cover off. I knew it was bad because of the singing frogs. Post-frog apocalypse, we mapped out a strategy whereby I pay them great gobs of money to net out the organics, supershock and flock. They didn't really want to bring in a trash pump because with the well water, they were worried about replacing water fast enough and avoiding a possible collapse. I believe that's pool guy speak for they didn't trust me to make certain the level didn't drop unsupervised and didnt want to be liable.
So three trips, $770 and a week later, I've seen no change in particulate level. They seemed to think floc would perchance replace the hard work of netting it out, because last night I easily found another wheelbarrow of leaf debris at the bottom of the deep end. They seemed surprised that their idea of shock (6 bags) netted only a hint of color change. The started to try to vacuum the shallow end after an unsuccessful flock, and broke the skimmer basket, and I suspect clogged the impeller, which I will now have to learn to disassemble, clean and seal. They're not coming back til next Wed. The instructed me to floc again on Sunday night.
I am thinking none of these plans will work out until/unless I A) remove more organic matter manually and b) supershock to 15 or higher to break down what's left if I can get pressure back at the pump and THEN floc.
Now, I'm a noob at pool school, but I've consistently seen reference to high sustained shock levels. Why do these guys not seem to agree?
Can anyone whose ever recovered a debris-filled pool outline the steps I should take -- at this rate, I fear the pool guys will end up soaking me for almost as much as a new liner and a truck full of water would ave cost. So I'd like to progress the recovery in the interim, sans pool guys billable hours except where it makes sense.
I believe he's told me the pool has 22,000 gallons, a Hayward 220t sand filter. Prior to the vacuum attempt, all mechanicals were deemed to be in good working order. The water is black, but turns brownish with shock, then back to back. They say they've removed 10 wheelbarrows full of leaves o far (clearly, when foreclosed, someone at some point left the cover off.)
So, should I 1. Net out more debris
2. Supershock to 15 ppm FC and sustain
3 then apply the floc?
Also, re pressure drop -- is it safe to run recirculate with low pressure, or will I burn out the pump? It's primed, but seems to also be getting air. On backwash, I do get water through. Right now I have it off until I figure out what to do next. But I suspect I shoukd not add shock etc until I've loved this one right?
Thanks in advance for any guidance you can offer!
