The link to the Pink Stuff at Amazon still works:
Kem-Tek 311-6 Pool and Spa 60-Percent Concentrated Algaecide, 1 Quart
Jacks Magic The Pink Stuff 1qt (60% HEDP)
But lets focus on basics first. You can use the CuLator regardless: if there is free metal in the water, the bags will capture some of it; if not, they will still work later. So:

1. Send me a set of *good* pictures of your current conditions. Please go for fully focused. When focusing through water, you may need to place something on the bottom for the camera to focus on -- a stainless steel fork will probably work. If using an iPad, send the pictures *full size* by sending from "Camera Roll*, one at a time, rather than from email. On my iPad3, you can also do it by inserting the pictures, and then going back to the top, tapping the CC line, and selecting the "Actual Size" option.

2. Do a set of tests on the pool, including CYA. It may help if you'll watch the Taylor videos: http://pool9.net/tk-guide http://pool9.net/tk-interfere

3. Go ahead and get the HEDP and the Culators -- but don't use them yet.

4. If you have any sign of algae, say so.

Lets's get your pool cleaned up, clear, and swimmable, and then see about next steps.
