Hello,
I have recently purchased a house that has a 2000 gal pond. The pond is built without a skimmer and has no filtration system in it. I have at least 20 koi fish that would like cleaner water to swim in. I have purchased a pump and now I need your help with what bio filter to choose. I am looking at Fishmate compact 16W bio filter, however I can't find any reviews. I would like to know if anyone tried this filter type.
Also I would like to know if any pond owners have a pond without a skimmer or how shall I correct this problem.
Thank you in advance.
Marta
