I am considering an above ground pond solution for my three shubunkins (about 5.5/6" including fins) so they can stretch out as it were and such. Yet, in my ignorance, I am curious.
At present, I have them inside with a 20g with 2 15g filters and I still have to change 50% of the water once a week... so, going from inside aquarium to outside above pond, I do not see filters/etc in the mini-ponds I have been looking over.. so, just out of intellectual curiosity is there a sort of biological filter going on with this outside ponds that is not present with the indoor then? otherwise, it would seem the bacterial/algae growth would be very sweeping without filters for the water outside.
I thank all in advance for their comments.
