Hi everyone!
I'm Roman from Argentina, i'm new to hidroponics and aquaponics... i have been reading the forum for a month or so, looking at the different systems and setups. Sorry for my english, it's not my primary language.
I got really exited with the idea of growing my own vegs without using soil and fertilizers.

I have been searching for an answer to my question but couldn't shed much light to it.
My question is if i can do aquaponics to grow vegetables (i don't want to eat the fish) using my current pond as the FT? (attached images)
The pond has been working and cycling for 6 months now, i has arround 750 liters, 10 small kois (arround 70mm long average), i have a pump in the bottom going to a gravity biofilter i made myself with a 20liter bucket filled with river gravel and some filtering medium.

I was thinking in a suspended grow bed to the right of the pond.
Will this work? Since it gets 5hs of direct sun there are a lot of algae and some floating plants.
if so, how large can be the grow bed? Should i add more fish? Should i remove the biofilter?




Thanks!
Best regards,
Roman
