Your levels are very SLAM friendly. Usually, we see people coming here with CYA through the roof, which requires a partial or full drain and refill to get it in line.
Just follow the SLAM process, and you should get that cleared up fairly quickly. With a CYA of 30, you'll add enough liquid chlorine (use Pool Math so you know how much to add) to bring your FC to 12 and test every couple of hours or as often as you can. The more times a day you test and top the FC back up to 12, the faster the SLAM will go. The key is keeping that FC at the SLAM level (12 for you) so it can get ahead of the algae and kill it all. Otherwise, you kill some, but some keeps growing and you keep spinning your wheels.
Good job getting a good test kit. I know they aren't cheap, but it will be your #1 tool in managing your pool and it will save you money many times over. You will never get "Pool Stored" again. Call it an expensive lesson learned.
