B. Scott,
Thanks for your input. I'm still a little confused though. Even though I plan to flush koi stuffs out to a sump area (gravity fed) no pump required just to remove the heavies at the pond bottom. I will still incorporate another separation system and still cycle pond water through filtration system (some bead system) and then possibly a trickle tower to introduce added oxygen and then back to the pond. I'm hoping this will address other impurities still in the water (I guess like the amonia)
Question 1: With a seive or micro-seive to handle separation, how often would you need to clean/flush those screens or the vortex? I guess the same concept except that the doots will be in the vortex sump and not at the pond bottom. Hmmmmmm.
Question 2: When you do water changes, do you run all water out through the vortex/screens or a separate sump area? Sorry, still conceptualizing a effective system to fit in my space allowed that will maximize my pond area. Thanks again.
