2. The following [substances] disqualify [a mik- veh] and do not complete [it]: water, whether tamei or tahor; water in which fruits or vegetables have been soaked or water in which they have been cooked; and marc that has not fermented. How do they disqualify [a mikveh] and not complete [it]? If a mikveh contains forty se’ah less one kortov, and a kortov of these [substances] falls into it, it does not complete it. They disqualify it with three lugin. But other [defined] liquids, fruit juice, fish juice, fish sauce, and marc that has fermented, sometimes complete [a mikveh] and sometimes do not complete [it]. How so? [If] a mikveh contains forty se’ah less one, and a se’ah of these substances falls into it, it does not complete it. [If] it contained forty se’ah, and he put in a se’ah [of these substances], and [then] he removed a se’ah, it [remains] valid.

3. [If] one rinsed in it [in a mikveh] olive baskets or grape baskets and they changed its color, it [remains] valid. R’ Yose says: Dye-water disqualifies it [the mikveh] when there is three lugin, [but] does not disqualify it by change of color. [If] wine or olive-sap fell into it [the mikveh] and they changed its color, it is invalid. What should one do? He should wait until rain falls and its color returns to the color of water. [If] it contained forty se’ah, he can draw [water, carry it] on [his] shoulder and place [it] into the [mikveh], until its color returns to the color of water.

4. [If] wine or olive-sap fell into it and they changed part of its color, when there [remains] not forty se’ah with the color of water, he cannot immerse therein.

5. [If] three lugin of water — into which fell a kortov of wine and its color became like the color of wine — fall into a mikveh, they do not disqualify it. [If] three lugin of water, less a kortov — into which fell a kortov of milk and its color [remained] like the color of water — fall into a mikveh, they do not disqualify it. R’ Yochanan ben Nuri says: Everything follows the color.
