I am always fighting metal in my pool water and staining on my fiberglass pool shell. I have always tried to stay on top of my chemicals but recently I noticed a slight amount of green algae appearing, just very slight. I was considering Slamming the pool but my CC calculation is always around .2-.3 so I held off besides my CYA is around 90 so lots of Chlorine. The other parameters are pretty much on the money so I took a sample to my local pool store to have them verify my numbers,,,, LOL ,,, you know what that means..
The guy was actually pretty good about it as I do buy things there when needed.
He said that pretty much everything was on the money as far as my number but he could not understand why the Phosphates were off the chart... He said they were so high his testing equipment could not give me an accurate number.
Being a salt water aquarium owner I know that any amount of phosphates in an aquarium lead to so unwanted algae problem so I purchase a product to bring down the number whatever they might be..
My main concern right now is how did this high phosphate problem develop... I have a very light pool load and its early in the swim season.. I do use a SunGuard product called Metal-out-plus do to the staining problem about 18oz every other week so I'm thinking that may be the source. I can not find out any product information on this Metal Out product.
Any members out their have an opinion on this??
Thanks in advance
