I'd like to add a filter(s), to my pond, with 2" Plumbing which is currently using
aqauscape skimmer and BioFalls/BioBalls Filtration, and a UV Clarifier.
I have less than a 1000g pond, with Koi and Recently added turtles, and I've been advised that I should consider using MORE than JUST biological filtration as I currently have.
I've seen various filters, some allowing 2", however they all seem to have built in UV Clarifiers, which I don't need as I am using a dedicated unit for that.
What do you recommend, and will I need to add more than 1 filter?
