NH3 MARINE WATER TEST KIT Ammonia (NH3) is excreted by fish directly into the water, and is also released from the breakdown of solid waste and uneaten food. Ammonia is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter. The only way to know what the ammonia level is by testing the water with an Ammonia test kit. Regular testing, will prevent damage caused by ammonia poisoning.

• Continuously monitors pH in freshwater
• No tests, no strips
• Lasts up to 4 times as long as competing products

Seachem pH Alert is a small unobtrusive sensor with a size that is almost half and lasts up to 4 times as long as competing products. It monitors the water 24 x 7 and changes colours according to the pH level. Seachem pH Alert continually monitors the pH level of freshwater aquarium and visually alerts you by colour changes on its sensor. Simply place the Seachem pH Alert in the aquarium or filter and it will monitor pH continuously. Its sensor changes color reversibly from yellow to orange to red, alerting you to shifts in pH levels between 5.4 and 8.0. Seachem pH Alert is for Freshwater use only.

Directions

Simply place Seachem pH Alert visibly anywhere in the aquarium or filter and match the sensor color to the corresponding pH reading on the color wheel. Its 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.

Indications

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.
