It's never WRONG to use bleach or Liquid Chlorine (Same as bleach only sometimes as strong as 12%).

"Pool Shock" can be anything, because "Shock" is a verb, not a noun, even though pool chem companies use it as one.

What's in the shock? It can be non-chlorine. Do NOT use this! It won't work with chlorine and will make things worse. It can be cal-hypo, which if your cal level isn't high is OK. It can be di-chlor, but this will raise your CYA and mildly lower your pH. It could be Tri-chlor but that will raise your CYA a lot and really push pH down. Or it can be the lithium-based chlorine--but this stuff costs more than gold dust and it's not really clear what its side effects are

Use plain bleach. I actually use a combination of pucks, cal-hypo, and bleach but keep an eye on CYA and Calcium Hardness and use the CH and pucks as appropriate. CH isn't an issue with a vinyl pool but I use the cal-hypo for convenience and just make sure the hardness doesn't get high. My pool got away from me this year as we had a few warm days and I was out of town. One of my friends used the words disgusting swamp and cesspool. I do brush with the vacuum brush but also can hook the hose to a return line and put it in blow mode. That kicks up algae and dead stuff in places you can't easily or safely brush. The filter then does the rest. Took 5 days to get it clear again.

update-

got most of the organic material out of the pool-
a lot what i thought was organic material turned out to be some sort of algea(slimy)walls and floor. vacumed some up through waste and brushed the rest. added a full gallon of bleach and will test in a bit. also added some 20 mule to bring my PH up.

now, why and how did this happen. what did i do wrong at close up? remember i do have a solid cover-

thanks-

[freddyttt]

New testing done-

PH 7.2
FC 1 ppm (confused to why this has not gone up)?
Combined Cl. 3.4

iv added about 2 gallons of cl. throughout the day. also backwashed a few times as my filter started ton read over 20(pressure)
also, backwashing although lowers the pressure slightly it does rise quick over 20 soon after.?((normal around 12))


please advise.

thanks-

the reason your FC is staying low is that you're adding bleach a gallon at a time. that's not even close to what you need for initial shocking of a pool that size with algae. i opened yesterday to the same sight, and i put in ten gallons last night, and it wasn't nearly enough. (18,000 gallon IG) i still have some green today. tonight i plan to put in 15 gallons or so. a very simple rule of thumb that i've used with pretty good success is shock at night and if your FC is down well below shock level the next morning, say around 1.5 PPM, shock again that night with 1.5 times as much as you used the night before. you have to keep shocking until the FC is close to shock level in the morning - if not, it means there's still a lot of living stuff in there using up the FC.

Thanks-

just added 7.1 gallons and did a full wipe down.
ill test Tuesday AM.

(11,000 gallon pool)


now the 7.1 gallons turned my pool green looking. i moved it around with my brush but should i be concerned about my liner bleaching? or staining?

thanks-

i'd be very mildly concerned about putting that concentration in a perfectly clean and stable pool, but if it's still green, probably at least half of it will get eaten up pretty quickly. i bet your FC is less than 10 in the AM, and probably less than 5.
