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

Smooth sunscreen
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Great for mature skin. Not easy finding something for mature skin that doesn’t cake or flake off. Moisturizing. I will buy again !

Very glowy
Style: SPF 50, Size: 5 Fl Oz (Pack of 1), Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
I just opened this to try it so I can't speak on if it breaks me out but the expiration date is good it doesn't expire until next summer. It's not thick at all very liquid actually but not a messy. I skipped moisturizer today to see how the hydration will be. I have severe dry skin so we will see. Very oily, glowy, moisturizing. I used it on my face and arms. It left a beautiful glow on my face so we will see how long it's takes to soak in. No strong smell which is nice and it's a large bottle!

Very moisturizing but clogged my pores
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
I like the texture of this sunscreen a lot, and it gives me a nice glow. However, it did cause me to break out a lot with small whiteheads so I had to discontinue using it.
