Hi

Surpised nobody has commented on this !! lol I have several garden pools plus aquariums and often use the water from them to water the garden Obviously with the fish and other life in the pools it's actually a weak fertilizer solution while it hasn't replaced the need to fertilize I haven't found it harmful in the least . There is a branch of this idea called "Aquaponics " with the goal of reaching an equilibrium between plant and animal if intersted in developing the idea further ?? gary
