With my first post here to TFP, I will say that I am a new pool owner in New Hampshire. Recently moved into a house with an AG pool that was mostly full from last year. I have been learning the pool owner game through different online resources as well as some initial information and products from my pool store, but ran into this forum a couple weeks ago and have decided to get all of my information here as I feel that it is a valuable resource and the information so far seems very good.
In joining the community, I have also ordered the recommended test kit (TF100) and received it today. Prior to receiving this in the mail, I had done several things to get my pool a nice clear blue and have gone through a few cycles of non-blue to blue by now. Those cycles have been mostly caused by the addition of chlorine turning my water to a yellow/orange color (all signs both from reading here point to iron in the water source). The latest cycle ended a few days ago when I was able to get my yellow water filtered out for the most-part and the pool turned clear blue. I took this opportunity to do some vacuuming, brushing and leaf raking in the pool to make sure that the next steps i took were unimpeded by a dirty pool.
Upon receiving the test kit, I tested the chemical levels in the pool:
FC - 0
CC - 0
TA - 180 (I realize this is high. I was using a pool store test strip prior to getting the TF100 and according to that test strip I am sitting around 100 here which is where I planned to be and adjusted accordingly)
CYA - 0
PH - 7.8
After taking these tests, I added 2 bottles of liquid chlorine (SHOCK-IT from pool store as I had a supply of this already), almost immediately, as somewhat expected, I noticed the water once again turning yellow. I have seen many posts about yellow water, but not many seem to be the same exact problem. All of those seem to suggest sequestrant. I am interested in finding out a sequestrant to use in order to try to get this to stop happening as I believe what will happen all summer will be everytime I add a significant amount of chlorine, the pool will turn yellow again, and I will have to wait a day or two before it will get back to blue and a day or two after that, it will be out of chlorine as it seems has happened.
So, what should i be looking for in sequestrant? Is this what the solution should be or is there something else that could be the issue here?
Thanks in advance for your help!
