ditto above - we are using the floating planter rings that koiguy described.
We also have a few of the regular planters up above the milk crates that are used for their houses and in those we have large rocks.
Our koi are not interested in the lil pads so far...they are smaller - anywhere from 4" to 8" (ish), but the previous koi didnt seem to bother the plants either and they were in the 14 to 16" range.
