HOW EC-504 WORKS

When EC-504 is applied to the water phase, algae blooms are controlled through competition. EC-504 remove nitrogen compounds from the water column faster than the algae and, as a result, the algae are starved out of existence or bloom is inhibited. In addition, EC-504 degrades accumulated organic waste, top scum and bottom sludge for use as carbon sources. The overall result is clean, clear water, free from algae, odors and sludge. EC-504 is designed to treat the cause, not the effect.

For copper based algaecide, the toxic action is attributed to the ability of copper to denature cellular proteins and to deactivate enzyme systems in fungi and algae.

For GreenClean, a bioalgaecide,

b. Mode of Action
Sodium carbonate peroxyhydrate is transformed into hydrogen peroxide and sodium carbonate in the presence of water. The hydrogen peroxide oxidizes the critical cellular components of the target organism and thus kills them.
