Hanna HI774 Phosphate Ultra Low Range PPM Colorimeter Marine Checker

Hanna HI774 Phosphate Ultra Low Range PPM Colorimeter Marine Checker is used to accurately measure phosphate levels from 0.00 to 0.90 ppm in marine systems, including reef tanks, to help ensure long-term coral health.

The HI774 Ultra Low Range Phosphate Checker® is a cost-effective way to measure phosphate in marine systems, including reef tanks. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompete sessile organisms for light, nutrients, and space, jeopardizing long-term coral health in your reef. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health.

The HI774 Phosphate ULR checker provides an accurate way to measure phosphate from 0.00 to 0.90 ppm in a few easy steps.

Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize. I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Strong and holds up to aggressive chewing
Color: Blue, Color: Blue
This was a fast favorite for our extremely aggressive chewer ('indestructible' toys are typically destroyed within hours)... this has survived about a week and still going strong.

My dog is a very aggressive chewer.
Color: Blue
My dog is an aggressive chewer and this lasted about 3 weeks before he started to get into the plastic and I had to throw away. It lasted longer than other chew toys so it was good. However the tail makes it easier for him to chew off into pieces. He gets nervous and needs to chew on something. I find the hard cheese sticks a better option for his nervousness.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.
