    Uhm, the vinager test tests the PH level... Not the TDS level. Two toatally differnt things.. Yes, you want the sand to not react to the PH of the peat... But also, you need it low in TDS.

    You can jsut make a pot, and run lots of water through it... But i've found that MUCH less effective and MUCH more time consuming....

    there are electron TDS testers available for 20-40 bucks. That's what I use. And yeah, i just test the run off... like the water i squeeze out of the peat, the rince water of sand... or if a plant is doing poorly, i run water through the pot and test that.... I don't know how effective other hardness tests are.. Like for fish tanks and such (kh and gh)

    Well, since I don't wanna pay 20-40 bucks, how bout I just wash it a few more times with distilled?

    hehe, if you just do it as described above it should be fine. BUT ALSO! keep in mind, that many many CP growers don't do anything to their planting media. So the rince procedures by many people is said to be "extra unessasary work"

    Arrg! Maybe I should start over with new sand and wash that with distilled instead of tap! This is getting too confusing I think.

    actually... If your tap water is decnet hardness wise, it is most likely lower in TDS than you peat was... i have tested peat at a starting point of 2000 PMM TDS wich is pretty high! So, just rince what you got a few times.. and it'll be fine i'd say.
