Fish poop?

Ok I gotta do a water change on one of my large tanks. My question is would this old watter be good for watering? The area of my yard where I normally dump it grows some hugh ass bushes and roses bushes compared to the area where I don't dump it. I just throw the hose out the same window every time. Any chemical I use in my tanks are fish and live plant friendly. All fresh water with controlled PH levels. I can assume it would be ok but I just wanted to get input, mainly from anyone who has done this. Thanks:thumbsup:

i would imagine it would nourish where eevery you dump it, its still good water but we want great water for our babes.

For sure use your old rez water for houseplants, grass, trees, outdoor plant, vegetables. It is still good for that.
