Seachem pH 警報

After nearly burning through cheap test strips every week, this sensor is a relief — it just sits in the tank and changes color. The claim about lasting up to four times longer sounds about right given how little I've had to fuss with it.

I've been using this sensor for about three weeks now and love that it gives me a constant pH reading without having to mess with test strips or chemicals. The color indicator is easy to read, and it seems to be lasting much longer than the last monitor I tried.

Tossed this sensor in the tank and it turned the right color within a minute, so I finally know my pH is stable without messing with test tubes. It's been reading accurately for weeks now.
