thanks for your quick reply dogghound.

i can't make the pond any deeper, because it is a large planter tub.
but i have put two oxygenators in the bottom which are already spreading across most of the pond and a tall grass/reed plant.

i have already put some ceramic plant pots on the bottom for them to hide in.

i will give it a couple of weeks and then make the swap..
