If it were mine I would do 4 things at this point,
1, go buy a cheap OTO/pH drop based test kit, these sell for about $10 at wal-mart, will be called something like 2 way drop test kit.
2, while there get some pH Down (dry acid), or if your comfortable handling it buy a jug of Muriatic acid (either one will work, pH Down dry acid powder is just easier to handle)
3, Get some bleach for chlorination, sooner is better than later, the big mistake people tend to make is fill their pool and NOT add any chlorine, this lets algae start to grow and then they have to start off on the wrong foot fighting it.
4, get some CYA stabilizer (you will want to hang this in an old sock in front of a return jet, as it disolves VERY SLOWLY)
Pool calculator says you will need about 28 ounces of dry CYA stabilizer to reach a CYA level of 30 ppm or (we suggest targeting 30-40 ppm to start with, I would say aim for 30 until your good test kit gets there), go ahead and add it first hanging it in the sock in front of a jet, kneeding it from time to time to help it disolve.
Once that is out of the way you will need to lower your pH (target 7.5-7.8 for now), do this by adding acid (dry or muriatic) about 2, or 3 ounces at a time, then testing after about half an hour while the water is circulating (note the common test only goes up to 8 for pH, so it may be even higher)
You will also want to get some chlorine in there, if using 6% bleach, you will need to add 50 ounces for an inital target level of 3.5 (which you can read on a cheap OTO test kit), test after a couple of hours and redose as needed to maintain 3.5 ppm.
that should have it for now, retest after a few hours and adjust as needed, try to do so in small steps, and stay away from any powdered chlorine products that may add CYA also.
