Hello to everyone here on the TFB boards! I have been spending some days trying to educate myself better and in more dept. as I try to resolve what I thought was a stain at the bottom of my vinyl above ground pool. I found this website and must say that I am really impressed with the amount of information and help this website provides. I admire the helpfulness that everyone offers in the forums, and although I am not much of a forum poster I thought I would reach out for some advice on resolving a very draining problem.
I will not list all I have done thus far as I have been working on this for some time but here is the latest.I did a test with a triclor tablet and vitamin C to see if my stain would disappear, however it did not respond. Two different pool stores have guided me bc I never really feel like one of them is quite interested or knowledgable . They suggessted I Shock with a non clorine product and add soda ash, and test with the vitamin C and clorine tablet, which i did. Stain still there. A few days later we took a sample to the other store (2) and explained our situation and brought pictures of the stain. They said it is black algea and said to add chlorine tablets to the skimmer, add Black Algeetrine, 1/2 gallon or muratic acid. The stain went away over night but came back two days later. It rained yesterday, so I shocked the pool in the later afternoon (we are running temps. at around 100 degrees in daytime and low to mid 70's overnight here). This morning the stain was gone so I took water samples to both pool stores so I could have a comparision to how equivilant or different the two stores were and to see what was going on. Here are the readings.
Store #1 Store #2
FAC 0 FAC .05
TAC 0 TAC .69
PH 7.0 PH 6.5
TA 0 TA 0
CYA 90 CYA 50
Calcium Hardness 300 Calcium Hardness 274
TDS 900 TDS 1500
Saturated Index -3.1 Corrosive
Pool #1 told me to add 1.5 pounds of Soda Ash and 2 pounds of Chlor Brite
Pool #2 told me to add PH plus and shock it. He said the Black Algea is "at bay" right now and to keep the chlorine high.
I am hoping I can get your opinions on this troubling problem. The stains are now reappearing as of 2:00 pm. I have not added the suggested chemicals as of yet but understand that I need to do something as soon as possible because of my results. Any help you can offer would be greatly appreciated. I am somewhat new so please forgive me if my questions seem very basic. I am continueing reading this site in hopes of having it all done at some point.
