On our pond, running 2 years now I am trying to do both. Submerged matala in one filter, Biostrata in another submerged filter and 9 cu. ft. of lava rock in a shower with a flow rate of 4500 GPH. We also flow 15 to 20 GPH thru the system with a stocking rate of 1000 Gal. per fish. I am a suspender and belt type and a newbi to koi keeping, this being our first pond.
