Something's in my water

[ihaveadane]

I have a Typhoon iii RO/DI unit. I guess I have made at least 80 gallons of water and all looked well. Last night I filled two containers and both have a blue, plastic feeling sediment. TDS meter shows the water is "pure" but I don't know what the sediment is...

1. Can I still use the water if filter out the particulate?
2. Where is it coming from?

Is it black? Could be carbon.

No it is a bright blue. Almost the same color as the web header color in this forum. It is about the size of sand grains. If I filter it out, I guess in a 5 gallon container of water I would get about a tablespoon full of blue stuff.

looks like my color changing filter is defunct. The seal broke and all the crystals are coming out.

Thanks for the help
