@ai6yr Looking good in the photo. My understanding is that with crossflow tests, after the full 15 minutes, ANY visible T-line, no matter how faint, is positive. But nothing also means nothing.
Back in February, when I had it full blast, the T-line would appear the instant the liquid reached it. Haha. No need to wait 15 minutes. That's, uh, positive. Lol.
@shuttersparks It was pretty instant up until today. On Tuesday the line went positive as soon as the liquid hit, and STRONG.
