Full Cycle
Product Application Guidelines: Plastic-Lined and Concrete Ponds
01
What this protocol is for
Complete product application reference for plastic-lined and concrete ponds from preparation through harvest. The grow-out dosage schedule is identical to the earthen pond protocol. Differences are in pond preparation only: no soil drying, use soft tools for liner cleaning, and the optional high-organic-matter pre-treatment step is not applicable. For plastic lined ponds with plastic lining on the sides but an earth bottom, follow the earth bottom pond protocol.
Main Objective
Provide a complete reference for product application in plastic-lined and concrete-bottom pond systems, from preparation through harvest.
02
When to use this protocol
Plastic-lined and concrete ponds, all species
Important Notes
- !
Do not use lime, dolomite, or zeolite with Blue Aqua system.
- !
No antibiotics, disinfectants during culture, pesticides, or herbicides.
- !
No water exchange. Top up only.
- !
For plastic lined ponds with plastic lining on the sides but an earth bottom, follow the earth bottom pond protocol.

Step by step instructions
Drain and clean liner
Drain completely. Remove sludge using soft tools. Remove debris and biofilm from liner surfaces and walls.
Optional: post-disease chlorination
If pond had a disease event in the previous cycle: fill to maximum level. Wait 2 or more days for pathogen spores or eggs to hatch. Apply 10 ppm free chlorine (bacterial) or 30 ppm (viral). Leave 3 days. Aerate on Day 4 to evaporate chlorine.
Incoming water disinfection
Disinfect incoming water with AlphaSep 1 to 2 ppm (10 to 20 kg per hectare). Leave for 1 day.
Mineral pre-treatment
Apply MinGro 10 kg per hectare (1 ppm) for 2 to 3 days with aerators running.
Phytoplankton check before stocking
Confirm Secchi disk reads 50 cm before stocking.
Day 1: Artemia supplement
Apply Artemia at 1 can per 200,000 PLs.
Day 4: SoilGro
Apply SoilGro. Following day: apply molasses.
Regular dosage schedule from 1 week post-stocking through harvest
Identical to earthen pond schedule. See Parameters table. AlphaGuard*L Plus applied daily via feed throughout.
