High Organic Load, Low Phytoplankton

Any pondBothTroubleshootingEmergency Response

01

What this protocol is for

An 8-day extended corrective schedule for conditions where high organic load is combined with low phytoplankton. Days 1 to 5 follow the phytoplankton crash, BGA, and overbloom protocol exactly. Days 5 to 7 add FytoGro and BactoGro to gradually rebuild phytoplankton alongside continued molasses. MinGro at 0.5 ppm is applied from Day 2 for 7 days.

Main Objective

Reduce organic load, correct ammonia, and gradually re-establish a stable phytoplankton bloom using an 8-day extended product schedule.

02

When to use this protocol

All pond types, both species, during grow-out when high organic load is combined with low phytoplankton

Important Notes

  • !

    Keep aerators running continuously. High organic load creates high BOD and low DO risk.

  • !

    This is an extension of the 5-day phytoplankton crash protocol. Do not skip Days 1 to 5 and go directly to the FytoGro phase.

Step by step instructions

1

Days 1 to 5: Follow the Phytoplankton Crash, BGA, and Overbloom protocol

Day 1: FytoShade. Days 2 to 4: SoilGro for 3 days. Days 3 to 5: molasses 2 kg per hectare for 3 days. Days 3 and 5: NitroGro. Apply AmmoTrap 0.3 ppm if TAN exceeds 3 ppm.

2

Days 5 to 7: FytoGro for 3 consecutive days

Apply FytoGro for 3 consecutive days to gradually increase phytoplankton.

3

Days 5 to 7: BactoGro alongside FytoGro

Apply BactoGro alongside FytoGro for 3 consecutive days to support microbial balance during bloom recovery.

4

Days 5 to 7: Continue molasses

Continue molasses application alongside BactoGro during Days 5 to 7.

5

From Day 2: MinGro 0.5 ppm for 7 days

Apply MinGro at 0.5 ppm from Day 2, continuing for 7 days.

04

Key parameters to monitor

Molasses: Days 3 to 7

2 kg per hectare per day

MinGro: Days 2 to 8

0.5 ppm daily for 7 days

AmmoTrap dose

0.3 ppm (if TAN exceeds 3 ppm)
