Hi guys, im new too this pond stuff, but i always wanted to get one since i was in year 6. \nBut my parents wouldn't let me, so instead i got lots of tanks and raised fish and various other aquatic animals in them. \n\nI just need a few questions answered, i use a fly screen to cover the pond is this poisonous? \n\nThe water is yellow, and the aquatic plants are starting to rot. I trim them, will the grow back?\n\nI use gravel on the bottom of the pond, but many decayed leaves and other droppings are sliding into them, will they get naturally removed?\n\nI 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.\n\nRight 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 \n:wink:\n\nThanks ^^.
