The guppies have been in the tank for nearly 24 hours and seem very lively, happy and eating well.
I have seen fish poo so this should help the plants pick up a bit.
At the moment the water is nice and clear and I feel the filter position and water flow is good.
I have decided I will get a picture backing for the tank. I am not a great fan of them but they do seem to give more depth to the viewing and help the colours of the fish stand out.
