PondZilla Pro

(4 customer reviews)

PondZilla Pro is a natural catalyst that accelerates chemical treatments by improving penetration.  When mixed with an algaecide or herbicide it speeds the breakdown of dead algae and aquatic plants while stimulating naturally occurring bacteria to fixate nutrients liberated during this process.    This complex blend of enzymes, cultures, fungi, and stimulants dissolves the dead algae and aquatic plants on a cellular level, reducing their contribution of nutrients.  By accelerating chemical reactions, PondZilla Pro improves copper algaecide performance.  This is especially critical in hard water applications when copper solubility and performance is reduced. PondZilla Pro alone does not kill anything.

Categories: ,

The cells of algae and aquatic plants can be thought of as a series of well-engineered structures. These structures are made of complex proteins, carbohydrates, lipids, and minerals. Chlorophyll is stored within the chloroplasts in the cell, and chlorophyll is how a plant gets it energy to grow from sunlight. This intricate framework allows algae and aquatic plants to grow and thrive while aiding in resistance to chemical treatments.

Improving the performance of contact algaecides and aquatic herbicides

Contact algaecides (copper products, peroxides, and diquat) must contact the cell wall and enter the cell to be effective.  Lack of penetration and intercellular movement of these chemistries reduces their effectiveness.  PondZilla Pro degrades dead plant cell walls and weakens cellular integrity when used with an algaecide formulation.  Killing all susceptible cells reduces the risk of algae developing any resistance to

Improving the performance of systemic herbicides

Systemic herbicides (i.e. glyphosate, imazapyr, or triclopyr) travel through the cell disrupting processes such as amino acid synthesis, cell division, and photosynthesis. Systemic herbicides tend to work slower, but they do translocate into multiple parts of the plant (1). However, herbicide resistance has been studied in detail (2) and can reduce overall treatment performance and consistency.  For this reason, we focus on a complete degradation of the dead plant structure and aquatic herbicide dispersion to all susceptible cells.

When combined with systemic herbicides, PondZilla Pro speeds movement into the cells by breaking down the cellular framework of dead cells, promoting rapid nutrient recovery, and decomposing dead plant material from the inside out. PondZilla Pro works synergistically with systemic herbicides and ensures thorough and complete degradation of dead aquatic plants.


NOTE: PondZilla Pro DOES NOT kill aquatic plants or algae.

    I add PondZilla Pro to all of my herbicide mixes and the difference it makes is significant! It greatly reduces the break down time of the targeted vegetation and it helps eliminate repeat treatments. I love the stuff!

  2. Zack C. (IA)

    PondZilla Pro has worked wonders for our customers ponds. It is helping with overall health of their ponds and showing long term improvements.

  3. Ashley U. (SC)

    Strong products, fast delivery.

  4. Chris S. (FL)

    I’m mixing pondzila with my herbicide mix on my golf courses. I can see that after my treatment , the weeds die and algae goes away but most importantly the algae doesn’t come back on the dead vegetation. This is very important on a golf course. Visible surface algae is one thing superintendents will not tolerate. The pondzila keeps the algae from regrowing and speeds up the decay of the treated vegetation. I use pondzila year round.
