Hi Everyone, this seem like a great site. I'm currently thinking about expanding my pond from 2500 gallons to 5000 and adding a stream. I'm currently running a 6000 gal pond skimmer, 2 2500 gal biofalls, and 2 pumps 3600 and 4200 (bio falls are roughly 4ft high). Currently each biofall is connected to a pump. I'm looking for input on two subject !st I'm trying to decide whether to add a pressurized uv filter for the new stream and best economical kind? Saw a jabeo 6000 w 18 wat uv for $179.00 "any input on this product" limited online information. OR make a planted sand /bio ball filter that feeds the stream? 2nd I know that i am currently over filtering my pond ( All eggs ended up in the skimmer) does anyone have any information regarding proper pond surface ? stability (how much top movement is to much) I look forward to talking with everyone further and thanks for any input
