Patio spring cleaning

We've had a busy day.  We've cleaned out the fish tank (Marlon, named for DCI Grace (Peter James), is currently residing in a plastic box), power washed the patio, and refilled the fish tank with rain water.  You may notice the "go faster" stripes on the fish tank - copper strips, in the hope of keeping out the snails, which 2 years ago devastated the plants in the floating baskets, and then took up residence in the tank.  

The water is now resting, before adding the fish.  We'll go to the garden centre on Monday to get some fresh plants.  I'd like some proper water snails - the Ramshorn type which I believe are not so keen on lobelias!
