Hi guys, im new too this pond stuff, but i always wanted to get one since i was in year 6. But my parents wouldn't let me, so instead i got lots of tanks and raised fish and various other aquatic animals in them. I just need a few questions answered, i use a fly screen to cover the pond is this poisonous? The water is yellow, and the aquatic plants are starting to rot. I trim them, will the grow back? I use gravel on the bottom of the pond, but many decayed leaves and other droppings are sliding into them, will they get naturally removed? I want a natural pond, with no filter running, is that okay? Or do i have to use a filter?, and if so are there any solar powered ones since i have no idea how to get a power source into my garden. Right now i have a Shurbunkin and a comet in the pond to test if the water is ok, i have 1 30cm koi, 3 baby kois and a comet soon to be in the pond :wink: Thanks ^^.
