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

Save Sanity (and Sinks)
Style: 20 Ounces, Size: 56 Count
These 20-ounce bowls have been a lifesaver for a big family with no time—or sanity—to spare for a sink full of dishes.
Don’t fill one with water and leave it overnight unless you’re running a paper-mâché experiment. For hot soup, I’d recommend using two bowls, but for cereal, pasta, snacks, or fruit, they’re perfect.
I even found one that had been left outside in the rain for a few days and it still hadn’t disintegrated—so sturdiness gets bonus points.
Also, three scoops of ice cream plus toppings? Tested and verified.
If you value your peace of mind more than your dish pile, these are the bowls you’re looking for.

These are great
Style: 20 Ounces, Size: 56 Count
These hold my hot and cold foods with no problem. I have not had an issue with leaking and it’s been safe to use in the microwave. I’ve even had liquidy foods in it. Like juices from the food. I have also eaten soups with no issues. Great price and durable.

Dermatologist recommended it!
Size: 1.3 Ounce (Pack of 1)
This is my 11th order of this product. I originally started using it a few years ago when my dermatologist recommended it during a period of hormonal acne. I’ve been using it ever since. I have very sensitive skin that usually reacts to almost everything, either with redness or breakouts, but I can use this cream comfortably without any issues. It is very gentle, deeply hydrating, and has become a permanent part of my skincare routine. It is definitely worth the price. Even a small amount provides excellent hydration and it lasts a long time. I also love that it has a natural ingredients and is fragrance-free.
