Good morning....I've been monitoring this site for a while, but this is my first post...
A little history: I've recently been victimized by crazy pool store test results. My pool is a year and a half old, and I use chlorine tablets. 1 year ago, CYA was at 50...now one pool store was telling me it was at over 250, and I've never added anything other than what the tabs add. My own tests, and now the TF100 Test kit comes in at 60-70.
A few weeks ago, my pool developed a very small mustard algae outbreak. I've been following the process in Pool School to fix that...I have a couple of questions:
1) I have 2 dogs that shed quite a bit. They do not swim, but their hair is still in the pool, and works well as skimmer socks! Right now, my overnight FC test is losing 1.5ppm, no CC. Could the dog hair in the pool create FC loss, or would you say I still have algae in the pool?
2) Post shock, I have debris on the bottom of the pool that looks like feathers. What is that? Does it need to be vacuumed to waste, or is it OK to let the filter get it?
That's it for now...thanks for any and all help.
