hi i need some advice about this please, i have bought a 1/2 whisky barrel to replace the plastic pond i had. its 24" deep by 36" diameter. i filled it with the original water from pond and put lilies in it plus some pond weed and then topped it up with tap water which i then added de chlorinator. it has now developed a milky colour and bad smell also flies on the top. it has a lot of what look like tiny tadpoles but are not, in the water which i have in abundance. also looks like a oil slick on the top which i think is pollen. i guess in my haste i should have washed the barrel out, but i didnt. it isnt lined as no fish will be added. the water lily has bloomed twice but the leaves are not looking too good. as you can tell no doubt, i am a complete novice. i have no splashing water on the lilies but put a pump on the bottom to give some circulation. i also have no filter except what is in the water pump. please help as i dont want to lose my lilies or plants. would greatly appreciate any help in this matter. i have very little money, as a pensioner, but if there is any simple way to cure this problem ??? please help, thanks chrissy
