Thank you for all of your replies so far. I generally keep sand on top because it helps to keep all the floating organic matter out of the water.
I will reply more in depth later, as I have had a busy day. But I am very grateful for all of the time spent to reply to me.
I will remove the ground plants, as you’ve convinced me.
One more thing, has anyone ever attempted a paludarium type setup with grasses growing on a high bank?
