Why black? Blue is what most people imagine when dying a pond – think Caribbean, and we do not dispute the beauty of blue but most “true blue” dye applications are influenced by the clarity of the water. Clearer water produces richer blues – not every pond has this advantage. Black dyes do produce a reflective quality akin to a mirrored finish that many people find pleasing. Like all color choices there is a subjective preference.
Note: Over time all dyes photo degrade requiring occasional maintenance dosing. Each (Blue or Black) of these quality dyes is designed to filter sun light helping to decrease nuisance growths of weeds and algae blooms.
Easy to apply – just pour directly from the container. This concentrate goes a long way.
