"Aqua-Pics Turtle KH Buffer 4kg

Introducing Aqua-Pics Turtle KH Buffer! 🐢🌊**

Hey aquarium enthusiasts! Do you have turtles or other aquatic animals in your tank? If so, you know how crucial it is to maintain a stable pH level. Water with low pH can be acidic and cause painful acid burns in your beloved pets! 😱 That's where our Turtle KH Buffer 4kg comes in - it raises KH (carbonate hardness), stabilizes pH, reduces stress, and stops those nasty acid burns.

This amazing product also contains added calcium for strong bones and shells, as well as chemically clean phosphates that won't exacerbate algae growth. And the best part? It's easy to use! Just add 1 level teaspoon or 5g to 10 litres of water, and you'll see a KH increase of approximately 7dKH or 125ppm.

We have two versions available: Turtle KH Buffer 4kg (the one we're featuring here) and Axolotl KH Buffer 2kg. Both are designed to provide the perfect environment for your aquatic friends.

So, what fish would you keep with this? 🐟 Would you recommend it to fellow aquarium enthusiasts? Let us know in the comments!
