Evolution Aqua K1 MediaMaturing the K1 Media bio media is important because a delicate eco system is naturally developing for the bacteria involved in the nitrification process. K1 Media provides the maximum active surface area for the bacteria to colonise, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water. As the K1 Media moves within the filter, it causes the old dead bacteria on the outside to be displaced.

I loved this sunscreen on my vacation to Cabo. Super effective even though it’s lightweight. Not sticky at all. I didn’t burn and I didn’t have to reapply continually. (I always burn lightly, initially, but I tan easily. Use your discretion if you tend to burn more.) And I love that the ingredients are clean!
