Do anyone know what i'm doing wrong or what I can do to improve my tancho kohaku hi.

I want to thank Nancy M, Mike M, fish breeder, Baytek Data Solutions K.K., aquitori, Papa Bear, moikoi, and etc. All your inputs had help me rethink what I should do about my koi pond.

Being a student still... buying a better filter system isn't the way for me to go at this point, but will happen somewhere later in time.

But realizing crowding is actually my biggest issue... The logical thing for me to do is to get rid of as much koi as possible and sliming it down to my only top 10 instead. Thats my best bet at this time! Especially when summers is about to roll in soon, decomposition of koi fecal matter will be really high.

Again thanks for everyones shared input...
