Jesse what you having growing in your pond is called blanket weed , blanket weed is a nightmare , the best way to remove it is to wind it round a stick , but leave at side of pond overnight to let all the crawlies climb back in the pond, the if you have plenty of oxygenaters in the pond as spring comes and all the pond plants start to grow it will starve the blanket weed , best to cover half the pond with plants to , you can use barley straw to help to and also some peeps use a clay but not sure about that one ,
