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

Effective
Size: L (up to size 11)-Pink
Fantastic. I put lotion on my feet & wear them when I go to sleep. I often wake up during the night and will remove them to find my feet soft and smooth. They are strong and fit my size 10 womens’ size.

Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌
