hello to all ,

wanted to know if anyone can please explain what the meaning of "square feet" and "surface area" means in terms of filter media. I never knew what it all means in terms of filtration capacity.

for example thinking of getting these 3000 bioball 1inch for $80, would this be enough filter media for a 2000gallon pond with about 12 koi about 12inch each.

thanks to all for all the input, can never really find a clear answer on this topics. hopefully someone can help. thanks again

An
