As new pool owner since last summer I have yet to learn the TFP method in regards to chemical treatment but my reading has begun. With that said, I am still at the mercy of the local pool store for water tests even though I have test strips and a cheapo amazon test kit.
Brief overview......moved into a new home last summer and the pool was open and crystal clear when we moved in. I started battling a green algae problem several weeks after we took over because of some severe rain for several days and I didnt have the time to maintain the pool. However, after 2 weeks of scrubbing, chemicals and vacuuming to waste many times, the pool was clear for the remainder of the summer. I was using pucks in the chlorinator at the direction of the pool store and was told to keep it full at all times (like 8-10 pucks with the dial on almost max
). When I personally closed the pool in late October, I recall the chlorine levels being very very high right before covering it. I believe the number was around 16ppm for free chlorine. Nevertheless, the pool was closed and I just opened it this week.
So after I pulled the cover the other day, the water is clear but there seems to be yellow staining along the edges/sides of the liner and on the white steps. I hoped it was some type of algae but It does not come off when I scrub the liner (even with some serious elbow grease). Since the steps are obviously not covered in the liner, I put a wire wheel on my cordless drill just to see if I could remove the yellow staining. It worked but this is obviously not the way to clean the liner. My brief google search suggests that the yellowing could be from excessive amounts of iron but the water test from the store shows iron at 0.
I'm wondering if the extremely high chlorine levels when I closed my pool caused the liner to be stained. Is that possible?
Until I get a proper test kit and learn the TFP method, Im stuck with what I have now. Ive attached the print out from the pool store from Friday (and yes, I added the alkalinity and hardness they suggested on the print out). The test strip pictures are from this evening.
