First thing is you need to get your own kit. Pool stores are notorious for inaccurate testing. I can tell by looking at your numbers that they are totally bogus. Test strips are no better.

The test kit that we think is by far the best is the Taylor K2006 or 2006C (better buy). Not available locally but you can get it through this link that takes you to Amazon: http://pool9.net/tk/

But, in the meantime, go to Walmart and see if they have the HTH 6-Way drops-based kit (no test strips!) and get that. If they don't, get an OTO/Phenol Red kit (yellow and red drops) instead. Use it to test and then post your numbers.

It makes no sense for him to tell you that you can't use dichlor. That is totally ridiculous. However, many pool chemical companies are adding unwanted ingredients into their products that can cause problems. I have no idea what is in the AquaChem products. What are the specific ingredients in the dichlor and trichlor?

For this evening while you are figuring out what to use, why don't you just add a little bleach to your pool. Maybe about 2/3 of one of the 121-oz jugs of Walmart's generic bleach. Pour it slowly into the skimmer while the pump is running or in front of a return jet. That will keep some chlorine in there and keep algae away. It won't take long for a new pool to turn green! It is fine to swim a half hour or so after you add bleach. Just give it a few minutes to mix in.

Until you get some CYA built up, your chlorine isn't gonna stick around long. So, you may have to add bleach a couple times per day.
