Recycle fish tank water for your garden

Updated Apr 21, 2022

Dear Cathy,

When I change the water from my fish tank, I toss the dirty water onto the lawn, not into my sink. The question is, will this water be good for my indoor plants?

– Bart Varacchi, Holbrook, New York 

Dear Bart,

Absolutely! If you have a filter on your fish tank and the ammonia levels in the water are normal, go ahead and recycle that fish waste by dumping it onto your lawn and plants. Your plants will love it.
