We just moved into a house with an IG pool about 8 days ago. The pool was opened on the second day we moved in, but it had an old cover on it and it was filled with polywogs and toads and the pool (after the cover came off) was brown. That all was cleaned up and the pool company that opened the pool said they added a lot of algae-cide and slammed it. We "slammed" it again the next day, and the next, and the next and every day since. We clean/brush it every day. It is a greenish-whitish-just a hint of blue and today we could see the third step on the ladder but can only see the bottom in the shallow end. We have a 28,000 gallon pool. The pH is 7.3, but after 6 days of slamming the FC=0, and the CYA=0. The pool company says we do not need to add CYA until the FC level is above 0, but from reading this forum it seems that's wrong? They also had us add a bunch of calcium, but since our pool is vinyl, that seems to have been a waste of time/money.
The DE filter is older, but is plugging away. I took it apart and cleaned it and added DE to the pool again - the pool company says I should clean it again with their "degreaser" if I want it to work better. I backwash it a few times a day and add a little DE each time.
So I have some questions - should I add CYA to the pool along with the chlorine (we are using store-bought 6% bleach now as recommended here to "slam" it)?
We have only one skimmer and we put in two 3-inch Chlorine tablets as recommended by the pool store, but they have dissolved very little if at all. Should I take these out?
We have found 3-4 dead toads in the pool each morning of last few days. Given the number of polywogs I'm not surprised to see toads, but dead?
Last question - the pool company says we should replace the DE filter with a sand filter as it would do a better job on our pool and if we had had one, we would be able to swim by now. Any thoughts? Sorry for all of the questions but we are very new to this. Appreciate your help very much
