Seachem Alert Combo Pack

The Alert Combo™ pack combines Ammonia Alert® (1 card) and pH Alert® (1 card). Ammonia Alert® and pH Alert® are almost half the size of competing products. At 1.5" x 2.5", they are small, clear, and unobtrusive, so they won't detract from the view of your aquarium. Simply place Ammonia Alert® and pH Alert® visibly anywhere in the aquarium or filter. It’s that easy. No chemicals or test procedures are required.

Ammonia Alert

Ammonia Alert's® sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. It detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia. Marine or freshwater use.

pH Alert

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. When first put in service, pH Alert® response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. Freshwater use only.

Care

No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with fingers, since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit.

To ensure Ammonia Alert® is functioning properly, the response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle (e.g. Windex glass cleaner): color should develop rapidly.

Sensor exhaustion is indicated by a visible fading or washing out of sensor color. Once exhausted, it is time to replace pH Alert®

Very sturdy legs!
Style: Zig Zag, Size: 28 inch, Style: Zig Zag, Size: 28 inch
The legs are very well built and good looking, however, the screws included for installation are only 9/16" long which is not nearly enough for table legs of this size. I installed the legs on a 30" x 83" live edge oak tabletop that is full 2" thick. I purchased 1 1/4" screws for the install making the table very solid.

Good and attractive with a few finish issues.
Style: Zig Zag, Size: 28 inch
These are attractive and functional and work well. Some of the welds were not as precise as I would have liked, and a few places (not conspicuous) are missing a little of the finish, but overall they do what they're supposed to do. I used them with a butcherblock counter top to create a desk for my office.

Very versatile table for many uses.
Style: Rectangular, Size: 28 inch
These legs work great for replacing a free standing rv dinette by reusing the table top . We didn’t need a table that converted to a bed. Nice fit and finish and great quality.
