We have a 15,000 gallon fiberglass pool that I've been taking care of for eight years the way the previous owner taught me. Well, it turns out she was mistaken about a few things and now I've got a situation on my hands. I've just ordered the K-2006C test kit but it won't get here for a week or so. Until then I've got to wing it with the kit I have. I know this is just a first greeting. but I wanted to let you know what I'm starting with. I'll find the right forum to post in to get help.
Everything looked great all summer until I swapped out filter cartridges and then the pool got hazy. After a week, I re-swapped the filters and they were covered with a brownish slime. I cleaned them off and put them to soak in water with a fair dose of chlorine while I used the other pair. The haze kept getting worse. I took a water sample to the pool supply store and my calcium was a little high and my phosphates were off the charts high. I've been told before and was told again, to do a partial water change. I've been afraid to drain water out of the pool for fear of damage to the pool (not popping out of the ground as we are on a hill well above the water table), but this time I did it. We took out and replaced over a third of the water. While the water was low, I checked the pool light well and found a light brown, bubbly slime. I sprayed it all with pool chlorine but without the pump running, I couldn't vacuum so didn't clean it out yet. So I have some sort of algae but I can't identify it from internet photos and the pool store guy didn't have a clue.
Here are my readings from the pool store computer. They mostly agree with my basic test kit except I show my alkalinity at 210.
Total dissolved solids 3500
pH 7.5
Total Alkalinity 145
Calcium Hardness 300
Optimizer 25
Free Chlorine 0.7
Total Chlorine 3.2
CYA 150
Phosphate 3847
That's where I am. I've started using liquid pool chlorine. Anyway, thanks to this site, I've learned a little over the years and hope now to learn a lot more.
