filtration of my pond

[abominus]

i allowed my pond to cycle for about 2 weeks. after a bacterial bloom, it became crystal clear. i added fishes and after doing a water change, it became blur again. i did even more water changes, but no affect. i had added a filter. cleared the pond in about a day but become blur again. what's going on with my pond. why does it stay blur. the pond has been running for about 2 months. the fishes are doing fine

I used a protein skimmer (DIY foam fractionator) as filtration on my ponds.
It constantly removes algae, detritus, DOC, and nitrate precursors, and spills them onto the ground as waste foam.
The plans were found on Koiphen.com under the title Phoam Phractionator.
Video of it working below.

so basically the bioballs or something like that needs to spin at a high speed to create foam and catch particles?

The vertcal column, is filled with lava rock, and the water is pumped from the pond and cascadesover the rock, fractionating the air water interface enough to separate particulate, planktonic algae, and other deleterious material as foam, that billows from the port.
It is the same concept as the foam that builds up under water falls, and under heavy wave action in takes and I'm the ocean

thanks a lot duanes
