See if you can get some in a small container, then add some vinegar. If it dissolves, then it's probably some minerals (carbonates, iron, etc.).
If it doesn't dissolve in the acid, get another sample and this time add some dilute beach. If it goes away in bleach, then it is probably bacteria.

Does this mean that the RO filter needs changed? I'm waiting for new ones to arrive any day now. Do I dare use this water?Originally Posted by BeakerBob
Had you used the bucket or power-head to mix salt previously? I often see a similar appearing residue on the bucket and power-head after mixing saltwater (RC) - even when using zero TDS water. I've read that many encounter the same.
