Crash

I rinsed it fairly well, just so most of the black was gone. Chemi pure is a good product I'm not knocking it but its the only thing I can think of that did it. I haven't used it before did it shock the tank or something. I don't know what's going on I tested my ro water from culligan tds meter was 3. Params are: nitrite 0, nitrate 5ppm (normal), ammonia 0, calcium 420, no phos I don't get it
