Seachem Alerts Combo

Seachem Alerts Combo is used for continuously monitoring ammonia levels and pH in freshwater aquariums without the need for tests or chemicals.

  • Seachem sensor technology
  • Continuously monitors ammonia and freshwater pH
  • No tests, no strips

Ammonia Alert™ is an innovative color device for continuously detecting and monitoring toxic-free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.

In the absence of free ammonia, the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. 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.

Why it is Different

Ammonia Alert™ lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia 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

As little as 0.02 mg/L of free ammonia will produce a greenish hue on the detector surface. This corresponds to a total ammonia (both ionized and free ammonia) of 0.25 mg/L in marine water at pH 8.3. In freshwater at pH 7.0, this corresponds to 3.6 mg/L total ammonia. Free ammonia is much more toxic than ionized ammonia. As free ammonia, the ALERT color corresponds to about 0.05 mg/L, ALARM to about 0.2 mg/L, and TOXIC to about 0.5 mg/L. The ALERT concentration is tolerated for several days, ALARM for a few days, and TOXIC is rapidly harmful. This product is not recommended for use at acid pH

Care

No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with your 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. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly.

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 to alert you shifts to in pH levels between 5.8 and 8.2. No tests, no strips, just constant readings. Freshwater Only.

Why it is Different

pH Alert™ lasts up to 4 times 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.

Directions

Simply place pH Alert™ visibly anywhere in the aquarium or filter. 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.

Happy Doggo
Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

Dogs love them
Flavor Name: Beef, Size: Small
My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!

Durable Nylabone That My Dog Loves
Size: Large
This Nylabone chew toy is a winner! My dog absolutely loves it and has been chewing on it daily for months, and it’s still holding up great. The durability is impressive, especially compared to other toys that don’t last nearly as long. It’s become my dog’s favorite chew toy, and I love that it keeps him entertained without wearing out quickly. Highly recommend for any heavy chewers!

Worth the money
Size: Large
My dogs love these! I was buying them on Chewy, but there a little cheaper on Amazon. I guess they're flavored because both of my dogs love to chew on them. They hold up pretty well too.
