Hello all,I wonder if you could give me some advice,my pond is about 1000 gallons I think,it is 8ft x6ftx3ft deep,I have 3 koi which weigh 26lb between them, also 2 x koi/goldfish cross which must weigh 4lb between them,also7 x goldfish which must weigh 2lb between them and3 x small rudd,My mum is getting rid of the fish in her pond because she is getting to old to look after them,she has 4 x goldfish/koi cross which must weigh 7lb between them,i would love to put them in my pond because they are her pets but would it over stock my pond,and if it did would it just need me to put another filter in, Thanks
