TDS meter to borrow?

[reeferj]

While cleaning out my reserve saltwater container I noticed a few small patches of maroon/brwn scum. It seems to be deep down inside the plastic, because a good scrubbing did little to clean it. Im afraid my R/O water may be the cause. Im in need of a hand held TDS meter to check what im workin with. Wonder if I could just take a sample down to my LFS?

I have an inline meter you could borrow/have if you like...i dont use it any longer...may be of some help although i seen you were looking for hand held

I need to make a trip to check the place out anyways.
