Help - brown stinky dark murky pool

[waterbear]

thank you for making me feel even more clueless.

It was shock, as the bag name I wrote says. I needed to shock as directed by all other posters, and it worked, as evidenced by my overnight change from brown to aquamarine, a more hospitable color.

From the standpoint of not knowing what it was, I mean that it had a chemical formula name longer than supercalafragilisticexpyalidocious.

could you really make a brown mudbog pool worse? If so, don't tell me how.

It could possibly make it worse. It is never a good idea to put anything into your pool if you don't really know what it is. Some things that seem like they might be the right thing could be disasterous if used improperly or at the wrong time...and some products can cause more and bigger problems then the problem they are supposed to solve! I tried to look up the MSDS for it on the net to see what was in it but couldn't find it. If you would post the indgredient list it would be helpful. From what I was able to read about it I suspect it was a monopersulfate based shock with a flocculant in it.
As far as your filter pressure goes, I would suggest backwashing it and adding a bit more DE powder (check the manual for how much your make and model takes...if you don't have the manual post the make and model and ask for help.)

People on here are really trying to help you but you are not really listening to them. It is your choice whether you want to follow their advice or not but you have a lot to gain (and will learn a lot in the process) if you do.
Just take baby steps for now as you learn about how to care for your pool and soon you will see all the pieces fit together nicely. Paitience is a key word with pool care. Quick fixes don't always work but approaching problems methodically with tried and true methods (that sometimes take a bit of time and effort) do!
