Well Water: Why you DON'T shock BEFORE using Sequestering Agent

[ChuckD]

Lesson Learned - why you should be sure to properly use sequestering agent BEFORE you shock you pool when freshly filling.




Ugly, isn't it? Yes, we did get it straightened out, but it required a couple of pump/filter setups running 24/7 AND several bottles of sequestering agent.

Some people cannot have water trucked in and have to use a well, but you really need to be sure you take care of the metal issues!

yup, saw my pool do that a couple times last summer (first year blues...or greens). Even after many, many hours spent on this forum I somehow missed the warnings of spectacular reactions you can get shocking well water with iron content. I thought then that I was adding untreated water that was sparking an algae bloom. So I'd shock and filter and brush.

Now I know better and run the hose directly into the skimmer and my DE filter seems to clean it pretty well, without adding too much to the DE load.

That's exactly what ours looked like. Yesterday we emptied it, scrubbed it down then refilled it. Right now there is A LOT of rust settling on the bottom & the top & we keep scrubbing the bottom to get it to come up then we get as much out as we can with the net b/c it's so thick or else the filter gets nasty too quickly. The water right now is actually green - big improvement from nasty brown but we are still working on clearing it up completely for blue water. So what can we do now to get it blue & get the rust out besides what we are doing? The chlorine is high - off the chart & the ph is around 7.2 - 7.3. I don't have other measurements b/c this is all the kit measures.
This is what it looked like before we emptied it

MsSmiley,
Read through all of the posts, you will need a sequestering agent. Add this to the water, and bring your ph down to 7 - 7.2. Keep your filter running 24/7. It will take some time, but it should clear up. Happy swimming!
