Hi, I want to fill in the pond in the picture below (sorry for the bad photo). It sits just above my pool - water from the filter is meant to flow into it and waterfall into the pool, however there is a leak in the underground piping somewhere so I have removed it from the circuit - the problem now is that it sits empty and fills up with rainwater, leaves, mosquito larvae etc, so I want to fill it. What would be my best way of filling it? I don't want it to end up like a swamp or for anything loose to wash into the pool when it rains
I was thinking of trying to break up the bottom and then filling with gravel and then rocks on top. My wifes suggestion is to "just fill it with concrete"......
Size is aboutj 1.8m x 1m x 200mm deep
Any other suggestions? Looking for something easy as it is quite hard to get to as you can't wheel a wheelbarrow up to it
