Description

Overview

pH Alert® is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly from yellow to orange to red alerting you to shifts in pH levels between 5.4 and 8.0. Freshwater use only.

pH Alert® lasts up to 4X as long as competing products.
pH Alert® is also almost half the size of competing products. It’s small, clear, and unobtrusive, so it won’t detract from the view of your aquarium.

Interpretation

Simply place pH Alert® visibly anywhere in the aquarium or filter and match the sensor color to the corresponding pH reading on the color wheel. It’s that easy. No chemicals or test procedures are required. When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes.

Care

No care is required beyond removing algae with a clean, soft material. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Sensor exhaustion is indicated by a visible fading or washing out of sensor color. Once exhausted, it is time to replace pH Alert®

I got 3 rats from here and they are super healthy and very good with handling! I was texting the owners for a couple days about the rats and they had very quick replies. Had so many stuff in the shop for cheap! Basically anything you need for any pets. Heaps of cages. Heaps of food. And great customer service! Spoke to me the whole time about what rat I wanted and where I came from. Will definitely be coming here every week!
