I now have a (new to me, but 5-6 yr old) 24' AG vinyl pool, 13500 gallons, Hayward pump and sand filter, just set it up within the last couple weeks. I live in a small village with city water, but it has metals in it, and in the past with an 18' easyset pool everytime the shock hit the water, it would turn brown. No exception this time either.
Last week the pool store suggested I put Revive in it, so I did, then 2 -3 days later I hooked up the pump/filter, vacuumed the little brown shadows out that had pooled at the bottom, which stirred it up a little and made it a touch cloudy, and then I shocked it with a bag of Booster from the pool store suggestion. This was a couple of days ago, then yesterday morning it was mud brown, no green tho. So I treated it with 3/4 bottle of Metal Free yesterday, as suggested by pool store. I also put a couple ounces of Tru Blue clarifier in it. We've had a lot of rain, so I keep emptying the debris from the skimmer basket, and periodically backwash the sand filter, which is pulling brown water out each time.
Here's the problems. 1) its still brown, but the Metal Free should clear it up, it just is agonizingly slow, from past experience. 2) Yesterday the readings were all good, except that Calcium Hardness was 325, and after a bad t-storm and lots of rain last night running the pump constantly, today it was 550 YIKES! The pool store guy was stumped as to why it jumped from 325 to 550 when the only water added was all the rain!
Other readings (by the pool store) were:
FC .2 (so I was told to put a 3" chlorine tab in the skimmer - done.
pH 7.0 not too bad, just a bit low if norm is 7.2 - 7.6
The pool store sold me and recommended for weekly use one 3" chlorine tablet in the skimmer, 3 scoops of EZ Pool, and 1-1/2 caps of Pool Perfect + Phos Free. I have not opened the EZ Pool or Pool Perfect and would consider returning it if I get better advice thru here at TFP. What are your thoughts on this regimen.
I am at a loss as to what to do next except what I have been so far, and that's keeping the filter/pump running, empty the skimmer basket of debris from the hard rains blowing yick into the pool, and periodically backwashing the brown water out. I also, today, ordered the TF 100 test kit. Should be here next week, so until then, I'll keep taking the water to the pool store to be checked as the test strips they sold me are junk in my opinion.
Any help will be much appreciated, thank you.
