Hello all. This is my first post. I first found the site because of a bad algae problem, but after reading up on Pool School, I decided to drain this little pool and start over doing things right this time.
I am refilling my kids' 12' round Intex vinyl pool (about 2200 gallons, cartridge filter) with water from a spring fed pond. In the pond, water is clear. If I fill a white plastic 55 gallon barrel with the water, it is clear.
I added bleach and some trichlor as soon as the water started into the pool because it will take about 2 days to fill and I wanted to be sure algae didn't start growing. Pump is not running yet. The pool had just been drained, scrubbed with bleach, then mopped clean. Now, even though water 4 feet deep in the barrel is clear, it is already looking very brown in the pool at only 12" deep. The water is not cloudy, just brown like weak tea.
I don't think it is anything growing because I tested chlorine and it is off the charts. I expected that because I put in enough to cover the full pool and it's still only about 1/4 full. I have only added Trichlor and a little bleach. I am waiting for it to fill before doing other tests/chemicals.
What is causing the brown, and what will be needed to get rid of it?
