Roy,

That sounds like a good start on a koi pond. Moving from your self filtered
lake to a recirculating pond will present some start up headaches, but the
improvement in viewing is worth it. BTW. Welcome back. RTB

I think the lake will still be the same, RTB. Roy, is going to build a
separate koi pond (just like the rest of us) joy, joy, happy, happy. )
