the koi are to big for it now. 13 koi in a 300 gal is outragous. then add the 6 turtles. plus your filtration is severly under powered. id find homes for the koi and just stick with the turtles.NOLAGT;5089209; said:I agree 100%. I dont keep the koi in there too long. once they get too big I swap out to smaller. I also do lots of waterchanges so its all good.
