Thanks, I see that now. I can use it just like the old Pool Math. It will recommend what I need to do and not just tell me what would happen. I could use it outside and not have to come inside and crank up laptop. So, let's say I added some bleach to get to 3 ppm like it told me to do. Then...

Although the App will tell you the effect of adding certain amounts of chlorine or other chemicals to the pool it doesn't just tell me how much I need to get to say 4 ppm if I only have 2 ppm. Maybe I need to subscribe to get that information. I like the way the old Pool Math would take...

Thank you. Pool Math is indispensable to me. That and all the support I have gotten here when I didn't know anything saved me. Moved in to this house Aug 2013 with 0 knowledge about pools. Somehow made it through the summer of 2014 and then looks like I found this website April 2015.

Please don't ever get rid of the original pool math.

I would do the chemicals yourself. Make sure you check your CYA and know how much chlorine/bleach to use.

Timb9, you have my sympathy. I wish, that I had a season as short as yours and glad I don't live in Florida. :cool: Anyway, I replied on another thread and you recently responded. From keeping the chlorine too low, I now have pink algae which is actually not algae but a bacteria. It is not...

FC does not increase but kills bacteria faster with lower PH.

I've had much the same experience as everyone on here with the stains coming back over the years. I've tried something new this year and seems to be working. I'm using Polyquat 60 so I can keep the chlorine low or just high enough to kill bacteria. Also, using HTH metal and stain defense. So...

I would put a half cup of ascorbic acid in if you think it is metal.

Believe it or not, later today, I saw Home Depot HDX 10% for $9 something.

Wal Mart Great Value bleach is now 6%. I had some bottles left from last year and they were 8.25%. When I looked at Clorox it also was 6%. Wal Mart has 10% chlorinating liquid for $3.64 and my local pool store has 12% for $4.60.

Thanks for your reply Swampwoman. The splotches appeared gradually. I use Muriatic mixed in water and then throw that in the pool. AA did not sit and if it had it would have turned the liner or made a splotch instantly. The liner looks like new where the splotches are as if I pored AA on that...

I've been treating for iron stains all summer and I am currently back at the point where stains had come back. I'm keeping PH at 7.1 and chlorine as low as possible. I'm now getting areas of the pool where the stain is lifting. Instead of the whole thing lifting gradually it is just specific...

Vinyl is a whole lot cheaper and isn't prone to algae due to smooth surface. It liner would need replacing after about 10 years or more but over all cost and maintenance are lower.

Thanks JoyfulNoise. So, 5.5 lbs of AA was about $48.00 and I used a pound of it. That turns out to be cheaper than the Citric Acid was and it works better and breaks down better. here's the link again if anyone interested. 5.5 lb (2500g) NEW 100% L-Ascorbic Acid Vitamin C Powder NonGMO...

Thanks, guess they were telling the truth. My liners only 7 years old though.

I guy in a pool store told me that the more a vinyl liner ages the worse it will stain and that when they are new they have some kind of coating that resists stains. Is that true or not?

Just wanted to share my most recent experience since I am becoming somewhat of an expert at this. I've done AA many times as well as citric acid. I have, in the past, dumped 5 pounds of Citric Acid in my 45,000 gal pool and another time 2 containers of Natural Chemistry's plus product which is...

Thanks JoyfulNoise. Thanks for confirming what I have been considering - using Polyquat 60. It seems to be a good solution because I have been through this cycle many times. It always seems that when the chlorine starts to hold then the staining returns and that is when I have been...

Thanks Swampwoman. As you know, the problem is if chlorine is kept at FC/CYA ratio then I am running the risk of oxidizing the metals on to the surface again.

I understand that Pro Team Metal Magic breaks down into phosphates over time. Can this develop into a serious problem? Thanks.

Why do you think your 3 year old got it from the pool? Adenoviruses are usually spread from an infected person to others through close personal contact, such as touching or shaking hands, the air by coughing and sneezing, touching an object or surface with adenoviruses on it, then touching your...

Welcome to TFP. The Aqua Chek strips are fairly accurate and cheaper. TFTestkits.net TFTestkits.net

Swampwoman, I would appreciate any update you could put in Pool School.

Anyone agree?

I agree there are many scams and bad products. Metal staining is a huge problem for a lot of us. TFP needs to have a separate section in the forum for staining be it metal or organic.

I really wish TFP was more open to different opinions. I understand the BBB method and the TFP method and it has helped me tremendously. There just happen to be new things coming out that may be beneficial. How about Polyquat 60? That is not really new but it is something accepted by TFP in...

So, the only time cellulose fiber will work is when the metal is out of solution and staining surfaces? - - - Updated - - - CuLator has good reviews on Amazon and other web sites - can you say they are bogus?
