Hanna HI98319 Marine Salinity and Temperature Tester is used to measure the salinity and temperature of natural and artificial seawater in aquariums.

Designed for Simple Aquarium Salinity Testing

Within seconds, the salinity and temperature are measured, and then using the temperature reading, automatically compensated and displayed on the easy-to-read LCD screen. Ensuring the proper salinity in your reef tank allows your fish and corals more time to grow instead of having to adjust to constant salinity changes.

Not completly indestructible but good buy
Style: Black chew toys for dogs, Style: Black chew toys for dogs
Dogs loved this. I have 5 pot mixed and they all have enjoyed this. I ordered two more after they enjoyed the first one so much. So far my dogs have not been as destructive as they have been in the past (especially on my couches). I have been home more recently so it could be a combination, but I think the bones have been helpful. Sturdier than the red Kong toys, but not as indestructible as the black kongs. As durable or more than the ruff dawg balls, and much more affordable than all of those. Also, some of my dogs are more selective on toys, but this one was an immediate hit, even with my dog that has shown now interest in ANY chew toy. We even walked through pet smart one day, and i tried to get him to play with every toy on the shelf- and he was not impressed. I even showed him the scented toys that cost $40-50 each. Happy that he took to this immediately. Keep an eye out. I heard one of my dogs hacking and coughing from the other room, but by the time I heard it and got to the room, it wasn’t clear what he was choking on. I had three of these bones in the room at the time, but there was also food and such around so hard to tell. Recommend supervising your dog with the toy in the beginning at least.

Lasts with a pitbull
Style: Black chew toys for dogs
Good for very aggressive chewers. Even large, strong jawed dogs. My 70lb pitbull loves them and they usually last 6 months before we have to replace (because she's chewed slowly down the ends) Would recomment!

Great, but didn’t last
Style: Black chew toys for dogs, Style: Black chew toys for dogs
I have a 70 pound pitbull and he absolutely loves this toy. Unfortunately, within a couple of hours this toy started to crumble. Now, there are large crumbs breaking off that he started eating, so we have to toss it. He’s only had this for two weeks.
