Spend your money on crayfish instead of koi. You don't want koi reproducing and creating muddy water. Koi are omnivours eating a lot of benthic invertebrates and are aquatic pigs rooting up the sediments and roiling the water in their search for food. The more koi you have the muddier the water becomes. I doubt very much that YP-SMB can prey on all koi reproduced.
IF you are "green" minded people consider Peroxygen Carbonate as an algicide (Phycomycin, Green Clean, Pak 27); very environmentally friendly. Keep us informed of your pond's progress. I would like to know when you have your first meal of yellow perch fillets. Keep an eye on the numbers of SMB. If you want more YP reduce the numbers of SMB, fewer YP then protect and increase SMB or manually thin YP.
