New Pool Owner. Help!

[Lewis Seguin]

Hi all. I have a 14 chapter on my torid history with this pool since it was opened in June but I will save that for a later date. I need help know. I have a steel pool with vinal liner. 24,600g. Cart filter. Normal chlorine pool. We bought this house last june and the pool was open so the pool co that was caring for it told us to use the 3" chlorine biscuts and shock once a week. Nothing about testing. This year we opened it and there was baskets full of leafs, bugs and who knows what. We ended up having a local co come and clean it. Short of the long we spent much on nothing. I am a salt water fish guy and belong to a forum which got me through alot. So I looked this site up. Sorry, got off the subject. I bought the Taylor K-6000 test kit and these are my readings:
Day one: 9:00 a.m.
pH 7.2
ALK 40
CAL 160
2nd Test same day(i needed to make sure I was doing test right) 3:13 p.m.
pH: 7.2
ALK 100
CAL 200
The next day I wanted to run the TC/FC and i was doing the test that required the power dippers. I took a sample and I could not get the water to turn pink. I was up to 13 dippers and decided to stop cause I had no idea what was going on. I did test the cyn acid and it was at/around 110. The pool was green then started to clear up and know it looks milky/cloudy. I wana use the BBB method and I have all the chemicals. I live in southern Minnesota and I have already been turned off by the pool co around here. Can some one please tell me what to do? I have a party that was planned for Sunday and they are all looking forward to swimming. Thanks all for your advice.
