How to Clean Your Fish Breeding Mop

Why cleaning spawn mops matters

This step-by-step guide explains how to clean your fish mop properly, so your fish spawn mops remain safe and effective for many years.

Remove the mop: Holding from the center of the mop, Swirl & Lift the fish breeding mop out of the tank carefully checking for fish or fry in the mop. Then move the mop to a clean bucket with aquarium water and lightly swirl again to double check for any fry/shrimp/snails. If any are found, put them back in the aquarium and move to next step.
Hold from the center and swish well in a bucket of tank or dechlorinated water. Spray with a hose sprayer if needed. Lightly rub together. Holding from center, shake well to release algae and dirt.
Avoid twisting the mop. Do not hold the mop from the ends of the strings.
Optional disinfecting: If you’re can’t remove the algae with simple swirling or you suspect pathogens, disinfect with 3% hydrogen peroxide. Mix 1 part peroxide to 3–4 parts water, soak the mop for 10–15 minutes, then rinse thoroughly.
Final rinse: Rinse the mop again in clean water until the water runs clear.
Add back to Aquarium or let dry: Gently squeeze the mop underwater to remove air and lightly swirl to bloom your AquaNest . Or air‑dry completely before storing.

Inspect regularly: Check for tangles; replace the mop if tangled.
Store spares properly: After cleaning and drying, store extra mops in a sealed container to keep them dust‑free.
