Need help with starting chlorine after drain/refill

[aciam]

OK. so I will drizzle the bleach in when the new water goes in. How much should I try to get in? it is cloudy and cold today so no swimming today - maybe I should shoot for 5-6 and add 1/2 gal of the 12.5 % bleach?

I think I will start out by adding CYA to get to about 20 at first - rather undershoot than overshoot. Can I mix the powder up in water and add it to the pool shortly after the bleach?

And then do I put a puck in the skimmer?

How would you do it if it were your pool starting fresh? I really like the BBB method and have printed off the reference sheets for me to use as a guide. So I am happy to scrap all the chemical I have in my closet and start fresh with what you all recommend. Thanks. aciam

If you add 1/2 gallon of 12/5% to a filled 10K pool, it will add a little more than 6ppm of cl. If you drizzle in the same amount to a partially filled pool, it will be higher than that depending on how much water is in the pool.

CYA is slow dissolving. You won't be able to mix it in a bucket of water and have it dissolved so it would just sit on the pool floor. You don't want that. Just wait until the pool is filled to get the CYA in there.

If I were doing a fresh fill, I would just add the CYA separately. But, there is not right or wrong way of the ways we discussed in this thread. If you want to add about 20ppm of CYA outright, and then use some of the trichlor pucks for a bit, that is just fine. If you decide to do it that way, please make sure the pucks are just trichlor and don't also have other things in them as well like copper for example. You can put pucks in the skimmer but you must make sure to run the pump 24/7 the whole time if you do so because they are so acidic.

I just thought of one drawback to adding some CYA and then going with pucks. It will require you to test your CYA more often throughout the summer. That isn't a big deal really, but the kits only have a certain amount of the CYA reagent. If you just add it outright, you won't have to test but maybe 2 or 3 times and then once the level is set, you can forget about it for the summer. Like I said, not a biggie.

thanks watermom - I have an unrelated question right now - at the end of last season we had a bad bloom of pink algae - we were using baquacil at the time and it was very hard to treat. I tried to bleach my ladder as best I could. I just pulled it out of storage to put it in the pool this morning and in my inspection I noticed that there looks like there might be a lot of dried pink algae stuck inside the bottom step. impossible to clean - and I'm sure the other step have some inside too. The ladder has hollow metal candy cane shaped sides with plastic steps screwed in for the above ground pool - the whole thing then screws into the metal deck attached to the long side of the pool.

I decided not to put it in the pool this morning becasue I was worried that the algae would "reactivate" in some way. I had looked into getting a new ladder last year but found it wouldnt be that easy. Do I need to look harder? or am I ok to put it in? I just picked up some polyquat that Ben had recommended for the pool and was planning on putting some in this morning ( although I admit I'm not sure of the dose - he didnt tell me that) Would that help? Thanks. aciam

My thought is to spray bleach on the ladder and then hose it off a half hour later or so, but I am not sure. I'll ask Ben about this. He is pretty busy this weekend and it may be a bit before he gets an answer back to us.

Regarding Polyquat, it should tell on the label what the dosage is per volume. Be aware that it will cause your FC to drop drastically, so you'll need to add more chlorine after a few hours to bring it back up. Having said that, I have a question for you. Did Ben suggest that you add Polyquat when you were battling your water problems before you drained and refilled? If that is the case, you don't have to add Polyquat to a fresh fill but you can if you want. It actually isn't necessary to use algaecides if water chemistry is maintained properly. I never do. But, it is ok to do so if you want.

I did bleach it last year but then put it back in the pool to use for the remainder of the summer once we cleared the pink algae. I am in no rush to put the ladder in - would rather wait and be sure than create another problem.

So, I did not use polyquat on my troubled water but spoke with Ben last night because my new fresh water ( after I added the bleach we talked about) tested a CC of 5 - which had me in tears. We discussed a plan to move forward which included polyquat because the man who brought the water suggested I test for metals before adding chlorine because he had seen some pools that he had filled go green after adding the bleach. Ben suggested polyquat to prevent that from happening since he figured the water man must know his water.

I haven't added it yet because I only have a FC this morning of 0.5. ( my cc is still 5.5) I added 3 lbs of CYA by the skimmer, and also put a puck in this morning - but I am assuming this will only bring the FC up a little bit. So, what should I do now? I had asked Ben if I should try to get the FC levels up by pouring in bleach but he said not to lest I turn it green. I think he wanted to bindup the metals with the poly first. But my sense was he just wanted me to run it at the low swimming doses for now and see what happened. So, should I add a little bleach first then a little polyquat? add polyquat then bleach? My pool is not green at all - should I scrap the polyquat? Can i add bleach with the puck in the skimmer? ( I know that is a basic question - sorry - I have no idea how to manage a chlorine pool)

The bottle of poly offers 2 doses - one for freshly filled pools ( 8-11 oz) and one for maintenance ( 2-4 oz) I could always just dose low to start, protect the pool from oxidizing metals and different colors and then I am free to raise the chlorine levels if I need to.

Sorry for all the questions and confusion. My ph is fine btw 7.6 and 7.8. alk 70. so not doing a lot on those ends. I went to Ben about my CC because it is just too complicated to post here. He had me check my reagents and we plan to watch the numbers for a bit. Apparently we are in unchartered territory - again. aciam.

It makes it difficult to help when we aren't given all the info. It may be best if you let Ben help you through this.

[PoolDoc]

+ Add the polyquat right away, and keep doing so at 1.5x maintenance doses. Get it in RIGHT AWAY; we don't want your pool to turn green, while the chlorine is low!!!!!!!!
+ Add the CYA
+ Run your trichlor tabs, and gradually increase them to gradually bring the chlorine level up, over a week's time.
+ Don't use bleach before then.
+ Use borax if the pH goes below 7.0

I understand. It is hard form me too because I don't always know what to do. I was hoping to still be able to ask the basic questions here through the forum if that's OK. And I figured you all worked together. The last time I had run into trouble you all sent me to him so I figured I would be proactive this time is all.

Like for example just now I tested : FC is up to 1.5 and CC down to 3.5 with no bleach smell for the first time since yesterday. My alkalinity is still 70 but my pH dropped to 6.8-7. ( probably from all the cya and puck this morning) I think I should add Borax? is that right? just can't figure out how much though. Is that OK to ask?

He didn't give me all the specific nitty gritty of how to proceed - like in terms of the poly and the FC dropping so that information is truly valuable for me. I hope I can still ask that here since I think you all are probably more available and more accustomed to answering those types of questions. thanks. aciam
