My algae issues

[True Blue]

I just tested my pool with my new K 2006 test kit. The DPD power top was open, so I lost most of the powder, but I was still able to get a reading with a bit that I found in the container.

Here are my results:

free Cl = 7.0 ppm
combined Cl = 0
pH = 7.2
CYA = 0

I went ahead and added another 3/4th gallon of bleach. I added five on Monday and have added 1 or 2 each day since. Due to the CYA reading, I went ahead and added some clarifier.

Yesterday, I could vaguely see the bottom of the pool for the first time.

I have a 7600 gallon above ground pool.

Any recommendations beside patience?

Keep adding bleach. In your pool, each quart of 6% bleach will add about 2ppm of chlorine. Until you get some stabilizer in there, you'll probably need to test it at least morning and evening and each time, add enough bleach to get back up to about 10-12pm. The more times per day that you can test and shock the pool back up, the faster it will clear. Also run the pump 24/7 while you are trying to clear this up. Backwash the filter as needed. Once you get it clear, then you can add some CYA.

By the way, I don't understand your sentence where you said that "due to the CYA reading, I went ahead and added some clarifier." Clarifier has nothing to do with CYA. CYA is cyanuric (or isocyanuric) acid. Not clarifier. Don't add anything else right now except bleach and Borax if your pH drops any. And, you're right --- patience is needed.

I would also call the company you bought the kit from and tell them the powder was spilled when you got the kit and ask them to send you a replacement bottle ASAP.

EDIT: What company did you buy the kit from? Please email us at poolforum AT gmail DOT com and let us know.

EDIT again: I read of two people today who had their kit arrive with spilled DPD powder. That is why I thought there might be an issue that we needed to look at. But, when I investigated it further, I realized that it was the same poster (True Blue) who had mentioned it in two different threads rather than two separate incidences. Thus, it is probably nothing we need to be concerned about. If it happened several times -- maybe -- but only once, I doubt it. I'm sure if you call them, they will replace it. Especially since we have problem sent hundreds of customers their way!

[True Blue]

Will do.

Also, I mentioned in another thread, I've been having problems with my multiport. I've determined that it isn't filtering properly. My pressure guage was broken, so I couldn't quite tell, but I suspected a problem. I read in another thread on here how to test for proper filtration using DE. I did that and my suspicions were verified. My question is, do I need to replace only the multiport? I assume that the filter does nothing more than hold the sand.

[Watermom]

Post this new info about your multiport in that thread instead of this one. You're more likely to get equipment help there rather than here in this algae forum since some of our equipment people don't frequent this section as much as that one.

My multiport issue is solved, so now I am just working on getting that "perfect" pool water. At the moment, the water is slightly hazy. I'm not sure that it even has any green hint to it. Here are the results from my morning testing:

FC= 20
CC= 0
pH=7.2
Alk= 85

I know that the pH is a touch low. I have always had difficulty in maintaining a higher pH. it was a 6.8 yesterday, so I added some pH plus (had it left over from last season - next time I'll use the BBB method).

Here are my questions:
1) How do I maintain a more controlled pH?
2) Do my readings indicate that my pool is safe to swim in? I'd really like to get in to vacuum it out.
3) How do I go from being a "restricted user" to a regular one?

[Watermom]

Try bumping your alk up a little with some baking soda to maybe around 100 or 110. It may help make your pH more stable. Start with a lb. of baking soda and test after a few hours to see what that does for you. Then redose if needed.

So that I don't have to reread this whole thread, please post your CYA reading.

Regarding not being a restricted member anymore, the fastest way is to bump up to subscriber level.

CYA level is 0.

I just skimmed the thread again and found this statement that you made earlier:

"Stabilizer...hard to tell, originally it looked to be less than 30 ppm, but later looked to be above 50 ppm"

So, now you're saying it is 0? Have you added anything with CYA in it other than the 8-oz. bag you mentioned earlier? Any trichlor pucks? Any actual CYA bought separately? When was the last time you tested CYA?

Those readings were with an old test kit and then with some old "dip and stick" checks. Once I received my K 2006 kit, I tested it and it was a zero. This was late last week.

I have added another bag of shock and used a couple of trichloro pucks. I have not tested the CYA since late last week. It appears that I was 3 more CYA tests left in my kit.

[Watermom]

Since you have no CYA, or very little, it is ok to go ahead and use dichlor shock and trichlor pucks for awhile, but monitor the CYA level periodically or else you may end up with too much. Until you start to get some CYA built up in the water, you may have to add bleach morning and evening. Once you start to see a CYA reading, you'll be able to test and dose in the evenings only. You asked if you could swim with cl at 20 ---- that is pretty high but with little cya, it won't stay that high very long. it is probably ok to swim but I think I'd wait until it came down some if it were me, maybe to 10 and then I'd wear an old suit. You really don't want to take the cl that high as it may bleach out your liner. I wouldn't take it any higher than 10 right now. Keep filtering and hopefully the haze will soon be gone. You're almost there ...............

EDIT to add: Dichlor adds 9 ppm for every 10 ppm FC added and trichlor adds 6 ppm for every 10 ppm FC.
