No way, either you are doing something wrong or the test kit is in error. a @ SSTP it is 6.5 mg / l @100 % saturation. 8 mg / l is 123% at sea level. Your tank would look like a fog bank with bubbles

123% it is!
Hmmm... well, I'm not at or below sea level. I'll admit that it's a cheap test kit. It definitely showed darker than 5 and looked very near 8 last time I checked. However, it did once show 11 so I will probably toss the kit when I get home. Thanks for the info! BTW, who makes the best (or reasonably good) test kit for O2? Salifert?
