Thank you Don. I will check out the link you posted, as I anticipated.
Let me clarify, my
MAIN FOCUS are the manufactured technological advances in last decade that have improved &/or grown the koi keeping hobby. Yes, I did mention bead filtration at the bottom of my original post.
I understand bead filtration has been around for DECADES, yet new bead filters continue to pop up. Have there been any major improvements and or developments in bead filtration technology over the last decade, other than better pre-filtration before sending water to the bead filter?
Respectfully,
