Seachem Prime raising TDS levels

[Jeffcccc]

I use Seachem Prime to dechlorinate my tapwater. I just tested it (after it passed through my RO unit) and the TDS level was .001. After treating the water with Prime I retested it and the level was .11.. Anyone have any theories.... and is that level high enough to be a concern? Thsnk you for your assisance.

The RO unit with carbon block filters should aready dechlorinate your water why are you using Prime?

Anything ionic will raise TDS. Prime has ionic ingredients (thiosulfate salts) and so will raise TDS. But that does not imply any problem.

That's what I meant to say.
