PondMAX · SludgeMAX
Natural pond sludge & muck remover
Slow-dissolving pellets of natural bacteria and enzymes that sink to the bottom and digest the muck your net can't reach — leaf litter, fish waste and organic sludge. Less bottom muck means cleaner water, fewer odors and a lighter load on your filter.

Digests bottom muck
Bacteria and enzymes break down sludge, leaves and fish waste at the source.
Sinking pellets
Drop them in — they sink and dissolve slowly right where sludge collects.
Cleaner, clearer water
Removing excess nutrients means fewer odors and less algae fuel.
Easy maintenance
No mixing or measuring liquids — just toss in the pellets on schedule.
