Silicone leftovers or something else?

[kilnakorr]

I have been testing my plumbing with tap water for the last couple of days.
I noticed last night the tank was very haze. I drained it today, and all surfaces are covered with this fine dust.

There's nothing in the tank or sump yet and only thing I can think of is I siliconed weir in the day before which might not have been fully cured.

I washed the tank down in RO water, and some of the dust collected at the botyom, so took a sample and a picture:

Question is, if I'm in any trouble or 'just' need to do a good clean, including taking all plumbing apart ?

Difficult to say what that might be from the picture. Is it soft and rubbery to the touch? When you drop it on a table top, does it bounce? If so, I'd say silicon.

Is your equipment out of the box new or second hand? If it is second hand, you may be seeing residue from the previous use.

I'm not exactly clear, +1 with Dom.

If that's coming in your tap water don't drink it!

Also, it is recommended that you use filtered water to make salt, but testing the tank with tap is fine. Silicone is generally safe but I would want to remove as much of that as possible to keep it from gumming up the works (socks, pump impellers, etc.).

But generally, silicone isn't a toxic worry. hth.

I can't really feel it at all. Very tiny so bouncing it isn't an option.
The picture is the dust at the bottom of a small test tube.

The return pump is second hand, but I cleaned it before trying it out.

It's not from the tap water
We have very high quality water here, without additives.
I will be using RO water later on, just testing for now

I was hoping, someone had made same mistake and could verify that uncured silicone would do this, as a good clean should be enough
