thanks bud,it's getting there slowly.
Good news !! i can get 7 @ 8 to 10" koi for £200,

a bargain me thinks,as one of them is beautiful and looks quality in my humble opinion, red and white and well balanced colours. I'm picking them up in 2 or 3 days and will post pics soon as.
ps pond conditioning about ready

water tests are
amm 0-12.5
nit 0-25
ph 7
water temp 20 oC
reducing the amount of k1 has done the trick + the bacteria boost
