Want to try BBB but not sure what to do!

Postby Guest » Wed 05 Aug, 2009 10:11

I am new to pool care, we've struggled with learning what to do all summer and I am sick of spending hundreds to get rid of algea for it to return in a week! I bought 6 of the big GV Bleach from Walmart 6% bleach. My test strips do not show my CYA (which I know nothing about). I typed everything I know about my pool into the Pool Calculator and it says I should add 622 oz to shock it. I do have algea in the bottom though and earlier in the summer we had to fight mustard algea and am not sure if it is that or not. Should I add more just in case or not? Do I have to have my CYA level tested first?
Also, how do I add the bleach, into skimmer or just pour in front of jets? This won't bleach my vinyl liner?
Im scared and if this doesn't work my husband will kill me! He thinks we should stick with listening to these people that know NOTHING at the pool store!
Any info is appreciated!

I wish someone would respond so I knew if I am doing anything right at all! I added 5 182 oz jugs of bleach to it yesterday. I keep brushing the entire pool but it keeps putting a layer of yellow algea on the bottom. The shallow end is pretty clear but the bottom of the deep end is still tinted green. I ran out of the stupid test strips so I am going to Walmart to buy the 6 way kit. I know you all reccommend the FASDPD but I don't have the money to wait for it and hopefully can convince my husband we need a kit that expensive. Will the Walmart kit show me if I have the pool at shock level or am I wasting my money? I am going to go get a bunch more bleach and keep adding it until it's blue again. HELP! I will post my results from the kit later this afternoon. Thanks to anyone who can give me advice.

Why isn't TFP allowing new members? I wish I could get on a more active board so I can get advice. I am reading everyone's posts but need individual attention! I guess I am needy! Ha

Jessi,
the kit you need is only about $12.00 at Leslie's. 3 bottle Taylor kit for FC -free chlorine and PH. Have the pool store test your CYA and the Pool calculator will tell you how much chlorine is needed for shock, based on pool water volume. The test strips are more expensive. The kit will test more times and more reliably. BTW, you may just catch a sale for the calcium hypochlorite 70% strong, ideal for fast shock.

You have to keep in mind the effect that the chlorine you are using will have on your water balance. Calcium Hypochlorite, like liquid bleach, will raise your pH a considerable amount so you need to watch out for that. Also, Calcium Hypochlorite will introduce calcium into your water so you will have to keep an eye on your calcium levels and switch to a different kind of chlorine if it gets too high.

A CYA (stabilizer) level of 30 is alright, but if you want to raise it a little bit you can buy stabilizer at any pool store. What CYA does is protect your chlorine from sunlight so that the chlorine is not oxidized out of the water before it gets a chance to do any sanitizing.

As far as adding the liquid bleach, adding it in front of the returns is just fine and it won't bleach the surface of the pool unless the chlorine level gets very high. All bleach is is chlorine.

Let me know if you have any more questions!

Oh and if you really want to make sure you don't bleach the surface, you can always add the bleach in installments, predissolving each installment in a bucket of water and spreading it around the edges of your pool. :)

TFP does accept new members -- about 15 every day have been joining and there are over 10,000 of them now after about 2 years. It's The PoolForum that no longer accepts new members.

If you have to get a less expensive test kit, get the 5-way at Walmart so you at least get your own Cyanuric Acid (CYA) test. Pool stores often give inaccurate results for this test and test strips do not do a good job with this test. You can use the DPD (shades of pink/red) chlorine test in the Walmart kit, but need to dilute your water if the chlorine level is above 5 ppm and unfortunately you could get fooled thinking you have no chlorine in the water when you have a lot. An inexpensive OTO (shades of yellow) chlorine test won't bleach out, but won't tell you Free Chlorine (FC) vs. Combined Chlorine (CC). I'm sorry the FAS-DPD kit isn't less expensive.

I do not think that there is any considerable rise in PH after shocking with Calcium Hypochloride.
Calcium hardness after sustained use, yes. Cal-hypo is not nearly as acidic as is Trichlor and even there, we are more concerned about CYA accumulation.
PH has a nice workable range and in pools with fairly new plaster the rise of PH actually works in our favor for at least a year.
Further, you can limit the PH fluctuation, by introducing borates in your pool, by adding Boric acid or Borax.
Pool calculator will tell you the amounts needed to achieve 30-50ppm.

All hypochlorite sources of chlorine (chlorinating liquid, bleach, Cal-Hypo, lithium hypochlorite) are roughly pH neutral when used over time since the initial rise in pH from these sources comes back down as the chlorine gets used up. This is because chlorine consumption/usage is acidic. However, in water that has a TA of 100 ppm and CYA of 30 ppm (as an example), adding 10 ppm FC would initially raise the pH from 7.5 to 8.0, but when this added FC was used up (came back down), the pH would drop back down if there were no other sources of pH rise (such as carbon dioxide outgassing). So it is not true that there is no pH rise from using Cal-Hypo, or any other hypochlorite source of chlorine, at least initially.

You are correct that when there is new plaster in a pool, it's curing raises the pH so acid needs to be added and that is when Trichlor tabs/pucks become useful since they are acidic. One needs to be careful, however, since Trichlor increases CYA. Even at 1 ppm FC per day chlorine usage, after 6 months of Trichlor tabs the CYA would increase by over 100 ppm if there were no water dilution.

In the above example of pH rise from hypochlorite chlorine addition, if there were 50 ppm Borates in the pool, then the pH would rise from 7.5 to 7.7 instead of 8.0. Just note that if one uses Borates in the pool, then one should not have dogs drink cups of pool water every day -- teach them to drink from a bowl of fresh water instead.

The BBB method is no good. I am a pool proff. and a water chemistry tech. Your CYA cyanuric acid AKA stabilizer it helps keep the chlorine in your pool factors such as the sun take chlorine and your stabilizer will def help, but it wont help with the green you will want to get that in there though. I will start with why you should not use Bleach it has a PH of 13, right now your PH is good. You will need to Shock though i would give you a calcium hypochlorite shock one pound per ten thousand gallons. This shock has 74% free chlorine and the average bleach has 14%. You need tyo make sure you keep chlorine to it . Have the pool store also check your phosphates this could also play a role in the green. How long has it been since you changed your sand???

The BBB Method
There are over 20,000 users at The PoolForum and over 10,000 users at Trouble Free Pool who use the BBB system or variations of it (plus countless more who don't register at these sites). BBB does not mean only using bleach. It means understanding your pool and its chemistry by using a proper test kit, understanding the chlorine/CYA relationship at least as far as the appropriate FC to use at a given CYA, knowing that a high TA leads to faster pH rise when using hypochlorite sources of chlorine, etc. The system is simple, easy and very effective at preventing algae using chlorine alone. One hardly ever needs to shock the pool nor use any clarifiers, floculants, algicide, phosphate remover, or other extra products.
