About This
- WHY SHOULD YOU PURCHASE THIS INDICATOR SOLUTION: The biggest reason is that it comes with 4dKH fluid and ph reagent PRE-MIXED. If you aren’t using 4dkh fluid your reading is very unlikely to be accurate. The indicator solution comes with a flip top bottle for extremely easy use.
- IMPORTANT- MUST READ- It is very important to use 4dkh fluid and ph reagent in your Co2 drop checker. If your drop checker directs you to use tank water then it will not be accurate and you will not have a good idea of what the actual co2 levels are. If your co2 drop checker doesnt list 4dkh fluid then assume you dont have it. Its a must have for optimum accuracy!!!!!!!
- Highest Quality 4dKH/PH solution. Monitoring co2 levels in your planted aquarium is very important for the health of your plants and fish.
- EXTREMELY EASY TO USE Solution- To use simply fill your drop checker half way with the Co2 Indicator Solution. Place the drop checker in your planted tank. Wait 2 hours to read Co2 levels.
- HOW TO READ CO2 DROP CHECKER- When your co2 is off the drop checker solution will be a deep blue color. After co2 has been on for around 2 hours you should notice the color change. Optimal co2 concentration will be at 30ppm which will be a green-light green color. If it remains blue your co2 is too low. If the color turns yellow then your levels are too high and may harm your fish. USE THE COLOR CHART ON THE SIDE OF THE CO2 INDICATOR SOLUTION or ON THE PRODUCT INSERT-

Great quality & interest
Keeps my Shepard/Husky occupied for 30+ minutes. She hasn't even destroyed it.

Good for medium and large dogs not good for small dogs
Too big for dogs under 15 pounds. Treats are hard to get out of the four corners. My dog can barely pick this up. She weighs 12 pounds. She still found it interesting though trying to dig the treats out that she was unsuccessful. Even after I cut all the little triangle prongs off the four corners the treats are still stuck in there. There is a slot on the side that I can put half of a dental refill in the side and she can eventually get it out so there’s still somewhat of play and challenge received, but not that satisfied to me.

Great for aggressive chewers!
Size: Jumbo, Style: Peanut Butter
I have a very very aggressive chewer. She is a Rottweiler/Pitbull mix. Most toys she completely destroys within 2 days, sometimes 2 hours. I must praise this toy as she has had it for over 5 months and has not destroyed it! She loves chewing the ends and carries in her mouth squeaking it as she goes. I have 4 pups and they all take turns chewing when they can. I will be buying more Playology dog toys in the future.
Thank you for making such a great toy!!

They are her favorites
Size: Medium (VALUE 2-Pack), Style: Beef, Size: Medium (VALUE 2-Pack), Style: Beef
We’ve had many dogs, many very destructive ones and wish I had these years ago. The hard toys get sharp edges, this toy is the best and yes is far better than the other red ones. My bulldog wants tug of war for 30 min to an hour every night. We’ve gotten tennis elbow, tendinitis, and pulled muscles holding onto this thing. She has tons of toys but 9pm and this is only option for her. We don’t get a choice. Easy to hold, well for a few min until your hand gets tired. First you one was about 3 years ago and she’s only on her third one. They last forever, easy to clean, and aren’t sharp edges. Seriously, better than any toy sold anywhere. My phone has hundred of pictures of Pickle holding this. She’s doing it right now. If you have a strong destructive dog that takes pride in destroying toys, ruin their confidence and get them this one.

Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!
