So I have literally just got back from my local pet shop, bought some aquarium gravel, rinsed it and finished my pond section! I filled it with tap water treated with aquarium dechlorinator just as a test.



Very happy with this as a first build so far!



The water is only around 2 cm deep, which I will keep an eye on to know when to empty the false bottom.

Only things I need to do now are get glass to replace this excellent tin foil lid stopping the flies getting in, and plant it!
