Soft water - but in a safe way Lowers pH and KH Adjusts the carbonate hardness Regulates the pH level For suitable soft and slightly acidic water Certain fish species, such as discus and angelfish, thrive in very soft water and particularly need these conditions for successful breeding. However, the water may have too high a carbonate hardness (KH), or the pH might have increased excessively due to natural metabolic processes, especially when housing different fish species. In such situations, sera pH/KH-minus offers effective and swift assistance. The pH and KH are quickly and accurately reduced and regulated. This establishes optimal conditions that significantly enhance the vitality and overall well-being of the fish. Tip: Set the KH to 4°dKH using sera pH/KH-minus, and then add sera super peat to the filter to maintain tropical soft water conditions permanently.Shipping Notes

Works as advertised
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
It appears to work as advertised very placed with product. I wish it was a little bit cheaper.

Just don’t do it
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
Be aware this is like drinking dry grass and water that very quickly turns to gelatin. I can’t imagine the Navy seal that must be able to do this. You would have to be trained for torture in order to enter this stuff.. Unless you were hellbent on suffering, avoid this like the plague. Absolute waste of my money.

Great!
Color: 2-Pack White, Color: 2-Pack White
I wish I’d have taken a before photo. But imagine a bunch of spices, on a little spice shelf that makes a U formation and a bunch of spices in the middle. So many spices. So much maneuvering to find the right one.
This- this is great! Organized, easy to see, reach. Neat. Excellent investment. It doesn’t even look like I have a lot in there, but I have 46 spices in there! And you’ll notice my cabinet has a lip. Easily fixed with a small piece of wood to raise the item.

Well thought out and easy to install
Color: 2-Pack Black, Color: 2-Pack Black
Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.
