PH of 7.4 is good. CYA of 30 is ok but I prefer 40-50. You can worry about that after the pool is clear. TA is ok at 140 but you might want to lower it just a bit after this is cleared up. Click on the PoolSolutions Guides link in my signature. There is a guide to lowering alk in there. CH of 100 is ok but actually in a vinyl pool, you do not need calcium. If it gets too high it can contribute to cloudy water.
