I water my houseplants and potted patio plants with the water drained from my aquarium filter as part of its routine maintenance. The canister filter is full of fish waste and nitrates that would provide a fantastic organic fertilizer supplement for plants. But that filter water is also full of nematodes (the scavenger, gravel-dwelling variety seen here).
I know most nematodes are harmless, but some nematodes feed on the outside surfaces of a plant, while others burrow into plant tissue. Does anyone now if this variety of nematodes can survive in the soil and harm my houseplants or produce?
