odd Bubbles in Spa and Pool

Not sure why my signature didn't save all my pool equipment so added below. I was also hoping the link to the pictures and video would offer some insight.

The store hasn't seen that type of bubbling before. She was concerned because my readings the last couple months have been low on chlorine. She suggested shutting chlorinator off and add 2 tablets to each skimmer basket to see if chlorine levels rise.
 
A couple of things to start with. You need to get your CH up and your pH down. You need to get your CYA way down and your FC way up. Your pool is debatably not safe to swim in with those levels. Get your chemistry right and then we can address the foam IF it's still an issue. I find it hard to believe that you don't have any algae and that your CC level is only 0.4 with your CYA being that high and your FC being that low. You would probably benefit from a nice SLAM this weekend. Definitely get your SWG checked out.

Hello gss1537,

I too, as Jay above said, think it looks like the foam that gets formed from using splashless, low splash bleach, but can't be sure until we know what's been added in there. Kind of looking like a big ole bubble bath right at the moment, isn't it?

To help clear it up faster, I would recommend getting a bucket, cup, or something, and scooping out all the foam that you can.

I have just a few questions:

What chemicals have you recently used in your pool?

Have you recently cleaned it with anything?

What are you using to chlorinate your pool? Powder shock, 3" pucks, liquid chlorine, etc.?

I agree with Al above that IF the pool store testing is correct your pH is too high and needs to be lowered to 7.2ppm, use the Pool math calculator to see how much acid needs to be added to do this. http://www.troublefreepool.com/calc.html

Your CH is low at 187, and will need to be adjusted to the 250-350 range.

Your CYA is too high to properly maintain your pool if that 144 is correct. (The only way to remove it is to drain about 50% or more of the water out and refill with fresh water to get it at a manageable level), but of course knowing how inaccurate pool store testing can be, we want to be certain what your exact CYA level is 1st.

Your chlorine is way too low for that CYA, if it is correct, and the chlorine needs to be raised to around 14-20ppm.

Your pH and CH at those levels can damage your pool surface and your equipment, and that high CYA is not going to allow you to be able to keep your chlorine level high enough to prevent algae and bacteria from growing in there . http://www.troublefreepool.com/content/128-chlorine-cya-chart-slam-shock

The single best thing you can do for yourself, and your pool, IMO, is to get your own test kit, and to start testing your pool yourself, instead of using the pool store testing, as their tests are very likely not accurate.

We recommend 1 of the following 2 test kits ONLY

1)TF-100 which can be purchased from http://tftestkits.net/TF-100-Test-Kit-p4.html
or
2)Taylor K-2006 which can also be purchased from http://tftestkits.net/Taylor-K-2006-p27.html as well as various other places online, and some of your local pool stores may also sell them.

Due to their reliability these are the only 2 test kits we recommend you use. Getting one of these kits will be the single best investment you can make to accurately maintain your pool/spa.

Please review this link: http://www.troublefreepool.com/content/123-abc-of-pool-water-chemistry

We will do our best to help you figure out what is going on with the foaming, and help you get your pool chemicals adjusted correctly, so they aren't risking damaging your pool, etc. and are safe to be swimming in, but you won't be able to use our methods, and the pool store methods too as they are different. (so you will need to pick one or the other, but not both).

But if you want us to help teach you our methods of pool management we will be more than happy to do so, as soon as you test your levels using one of the recommended test kits, so we can see where they really are at.
Using the Pool Math Calculator http://www.troublefreepool.com/calc.html and only until your recommended test kit arrives,

1)I'd recommend you use Muriatic Acid (per pool math calculation) in front of a return with the pump running (Be very careful when handling MA and avoid breathing the fumes)to lower your pH from 8.1ppm to 7.2ppm.

Sweep/brush the pool bottom below where you add incase any settles, and wait at least 30mins with the pump running between each chemical add

2)EDIT:Add 1 gallon enough Regular Liquid bleach ONLY per day (active ingredient needs to say Sodium Hypochlorite), (Do not use low splash or splashless bleach because it will foam and you will again have a bubble bath effect). Do this with the pump running, slowly pour in front of the return, and sweep the floor where you poured it in case any settles until you can test your levels using your new recommended test kit.

This will prevent the issue from getting any worse until the levels can be properly tested. If the chlorine/cya levels aren't adjusted accurately it is not safe to swim in it, and you are going to without a doubt end up with an algae outbreak if you don't get the right amount of chlorine in there very soon, that is if you don't already have algae growing in there. END EDIT
It's very possible you already have algae/bacteria growing in there with those levels, depending on how long it has been that low, but only time will tell.

3)You'll need to adjust the CH to the 250-350ppm.

Test all your levels when your new kit arrives, list them here, and we'll go from there.

If you have any questions please don't hesitate to ask because we are all here to help you.

I hope this helps, and have a wonderful night :)

Welcome, GSS! gorgeous pool you have there!

I saw foaming like that once at a vacation spa after a party ;) It is not exclusive to splashless bleach, it can also represent a water quality issue combined with lower calcium.

It definitely needs to be slammed to oxidize everything, then sanitized properly per the cya:FC chart in my signature on a daily basis.

But as crackerjack mapped out, the first step in getting control of the water quality is the proper test kit so that you're able to read your cya and higher FC levels while slamming, and a partial water change to (with SWG) get to about 70 CYA.

I am betting that a 50% water change followed by a proper SLAM (shock and maintain) will eradicate the problem, but it sounds like thereafter you may also need to check and see if your salt cell needs cleaning/is operating properly. You won't be able to tell until you've cleaned up the water to give it a chance to produce enough chlorine. Don't run your SWG while slamming...use only liquid chlorine or straight bleach (NOT splashless bleach.)
 
thank all of you for responding. I will need to get a test kit ordered so that will take a few days to get it.

I noticed the term SWG used and that is Salt Water Generator, correct? I have a chlorine pool and not salt. I had some algae about half a month ago but got that under control and put new filters in 9/26. I say it is under control because nothing is visible.

I am using the 3" tablets in the chlorinator.

here is the chemicals i have used recently so not sure if that would attribute to the foaming effect.

Good job pulling the trigger on a proper test kit. If those levels on the pool store report are correct, you still have algae. You just can't see it yet. You should probably stop using 3" inch tablets because that's just going to raise your CYA even more. I would wait until you get your kit and know what CYA actually is before start draining. None of those chemicals you're using will cause that much foam. That algaecide will foam a little (even though it says no-foam) but not that much. That "chlorinating liquid" is the only one of those 3 chemicals you need to buy in the future. There is a good possibility that the foam is a combination of a few things, one of them being low calcium like Swampwoman said.
 
Hello gss1537,

Thanks for the info on the chemical adds. I'm researching them now to see if one or a combo could be the contributing culprit to the foaming issue.

+1 to Swampwoman, and AL's comments above.

If you have any 3" tablets in the chlorinator now please go ahead and remove those, and use ONLY liquid chlorine (bleach), no powder shocks, or pucks because they will continue to contribute, and add to your already too high CYA level.

Also please click on Settings at the top right of your screen, then Edit Settings under the MY settings bold tab and ensure your pool info is in there. if it's Not in there please add it; if it is already there, please ensure you click Save Signature, and also that little check box that says Show your Signature is checked at the bottom of your Quick reply screen. Perhaps that will get your Signature following you like it should :).

Order your kit today if possible because the longer those levels sit uncorrected the more chance you have of plaster damage to your new pool, and we certainly don't want that to happen if we can prevent it.

Just a FYI-The TF100 gives you a lot more bang for your buck and with a potential slam most likely going to be needed. You might want to also consider getting the XL option for this kit as to not run out of supplies while Slamming. When you are on the TF100 order page there is a little box on that page that says XL option just check that option to add it to your order. http://tftestkits.net/TF-100-Test-Kit-p4.html

EDIT: Also since you are going to have to do at least a partial drain and refill to get that CYA level down to keep from just dumping money down the drain, so to speak, let's just have you only add 1 gallon of bleach to your pool daily until your test kit comes in. That should be enough to keep the issues from getting any worse until you can properly test them. END EDIT

I hope this helps and have a wonderful day:)

I think I found my culprit on the bubbles from my pics and video. I am still waiting on my test kit to arrive and just adding liquid bleach since then so i had some time to experiment.

I filled a glass of water and added a few drops of this to the glass and it bubbled. I'm going to try filling our bath tub with this stuff tonight and see if it creates a bubbling/foaming effect.

That is essentially a phosphate remover and it will cause some foam in your pool after adding. It's usually only where water splashes though, which wouldn't explain your hot tub overflowing with foam. However, if you're using the recommended dose of 8oz/10,000 gallons once a week, there's no way it will foam as much as your pool is. IF that is what's causing the foam, then that's an easy fix because once you get your chemistry under control you won't have any algae and you will probably never use algae treatment again (unless you get lots of organic material in your pool often).
