Cloudy Water

[ivyleager]

one more quick question...do i address the iron...if i add any pool magnet plus as instructed to rid of metals, it says to not shock for 7 days...so do i add the bleach and address the iron later if at all? please advise...thanks!!!

An iron reading of 0.2 sounds miniscule to me, but I'm no expert on that metal. I'd refrain from adding anything else, and stick with the plain unscented bleach, and keep it up to 20ppm. Once your pool clears, then you can begin addressing the other issues.

Oh, and keep adding the bleach to maintain the free chlorine level up @ 20ppm. Good luck.

you need to look at ben's best guess chart for cya levels, i will put a copy here the 20 is just while you are having to stay at shock level.



Best Guess CYA chart
________________________________________
Ben's 'best guess' FC/Stabilizer table for algae free operation of OUTDOOR pools -- as of July 2003 --

Use the info in this chart to help you figure out what levels of chlorine you need to maintain in your pool based on the amount of CYA (cyanuric acid, also called stabilizer) that you have in your pool. (FC = free chlorine)

Stabilizer . . . . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . . . 8 ppm . . . . . 15 ppm . . .. 25 ppm

Frustrated,

Guess what! All the times before when you added "shock", you were actually increasing the chlorine to many times higher than 3. That's the whole point of "shocking".....getting the chlorine high to kill (or shock to death!!) the evil algae or microbes in the water. The 20ppm is just for the shocking level. Here's the chart below as a reference.

Stabilizer(CYA) . . . Min. FC . . . . Max FC . . . 'Shock' FC
=> 0 ppm . . . . . . . 1 ppm . . . . . 3 ppm . . . . 10 ppm
=> 10 - 20 ppm . . . 2 ppm . . . . . 5 ppm . . . . 12 ppm
=> 30 - 50 ppm . . . 3 ppm . . . . . 6 ppm . . . . 15 ppm
=> 60 - 90 ppm . . . 5 ppm . . . . . 10 ppm . . .. 20 ppm
=> 100 - 200 ppm . .8 ppm . . . . . 15 ppm . . .. 25 ppm

Most people don't swim during the times that they are shocking the pool, because they are trying fight off contaminates in the water. Once the water clears and contaminates are killed, then the chlorine level is allowed to go back down to maintenance levels. In your case with a CYA of 90, you'll need to stay between 5-10.

Also chlorine is chlorine, it just comes in different forms and many different kinds of products. I used to use pucks, which provided the chlorine for my pool. Now I use bleach, which provides chlorine for my pool. Some people use granular pellets in a floating device, which provides chlorine for the pool. IT IS ALL THE SAME CHEMICAL COMPOUND IN THE END, and your pool doesn't care which one you use, as long as it gets its' sanitizer.

How's the pool looking? Is it clearing? What are your current numbers? Good luck.

yea i realize the shock shoots the chlorine levels up. just never have kept chlorine levels high for days like this...wanted to make sure i understood exactly what you are saying so i don't screw up and make it any worse. i do appreciate very much you bearing with me and helping me. honestly, thanks very much. the pool is still cloudy, not as bad, can see the bottom. i don't trust my judgement on the water testing i do, but today my readings are chlorine 15, ph 7.5, ta 180. can't test for cya. keep the levels high until it completely clears...is that right? also, i could stand to add water as the level is down due to backwashing, etc....but should i hold off on adding water until this problem clears.if it ever does? thanks

computer results today
TDS 1100, cya 93, total chlorine 10, free chlorine 7.9, ph 7.5 total alkalinity 115, total hardness 453
water unchanged..still cloudy but can see the bottom
would appreciate some advise. thanks

With a TC of 10 and FC of 7.9, then your CC should be 2.1, which means you need to bring your chlorine up to "shock" level, which with a CYA level of between 90-100 would be 20-25ppm according to Ben's Best Guess Chart. This should bring your FC & TC into balance and your CC down to 0 (or at least down to less than .5, which is acceptable according to most of the "gurus" on the board).

Frustrated,

Looks like you have combined chlorine of 2.1. Keep adding the bleach, needs to be higher than 10, up around 20-25ppm to be effective.

Yours is a vinyl pool, right? The total hardness (calcium) is a bit high. It could be a contributing factor to the cloudiness. Once the combined chlorine is dealt with, then this needs to be addressed. Most advocate partial drain and fill, if fill water calcium is low. You may want to browse the "Dealing w/ Alk and Calcium" section.

PH and alkalinity look good. No worries there.

The TDS seems high, as mine is only in the hundreds. Calcium can factor into that value. Here's a recent thread: http://www.poolforum.com/pf2/showthr...ssolved+solids It, too, advocates a partial drain/fill to lower TDS. If so, fill water needs to be tested.

Keep adding the bleach to get the chlorine up, pump and filter 24/7 and have patience. It took awhile for the pool to get this way, will take a while to correct.

Good luck.

guys...when i first starting adding the bleach combined chlorine was .5 and now it's 2.1 after adding all this bleach...so you still advise to shock to 20-25?? seems like i just keep getting worse instead of better as far as the readings go....is that normal and just keep shocking and keep it at 20-25 until it clear??? just want to make sure??

[Sherra]

Yes, your CC can go up...it's the amount of chlorine that's been "used up" but is still in the water.
