Tetra Pond AquaRem™ Working with a filter, AquaRem quickly clumps suspended particles and free floating algae.
This allows the filter to easily remove these "clumps" from your pond water without harming the natural balance of pond life and plants. For clear water in your pond, use AquaRem.
CrystalClear RapiClear is designed to clear water gardens and koi ponds quickly and safely by combining suspended particulate together. This process is commonly called “flocculation”. Flocculation basically means that suspended organics within the water column attract together, making the accumulated mass heavier than water. This “mass” will eventually drop to the bottom of the pond where a good bacteria colony can utilize the organic mass as food and remove it from the pond, or it will simply get removed by filters, skimmers, etc.
