You would be doing yourself a favor to leave the SWCG off for now, get the water balanced, and THEN turn it back on and use it for maintenance. They are much more efficient at maintaining chlorine than they are at clearing up water issues. The problem right now is that we are just guessing at your water parameters with strips, which isn't going to get us/you anywhere. Try going to WalMart and see if they have the hth 6-way drop kit that sells for around $20. If they have it, get it, run a set of tests, and post your results here. If they don't have it, then get the cheapie ($6 or so) OTO kit (it uses red and yellow drops for pH and chlorine) and test with that and let us know the results. If all of those aren't possible, then take a water sample to a reputable pool store and have them test your water, give you a printout of the results, and then come post those here. Resist the list of stuff they're going to tell you you have to buy--just smile and tell them that you already have it at home. Once we have a set of water test results to look at, then we can give you helpful advice. (Make sure they actually give you numbers for your test results--not just "good", or "low", or "high".

In the meantime, you need to keep some chlorine in the pool. How much to keep is really dependent on your CYA level, which is why it's crucial to know what it is--but at least try to keep 4-6 ppm of chlorine in there until we have some definitive answers. I calculate your pool's volume to be around 13,500 gallons. In that amount of water, each 1/2 gallon of 6% bleach you add will raise your FC by just over 2 ppm. So..I would add a gallon of bleach every evening until you get test results, and then we can help you go from there.
