My tank filter aquaclear broke after like 5 years and was going to replace it, but I'm moving my turtles over to a indoor pond next month so I figure I would just use the new filter I plan to buy for the pond, for the month they have left in the tank. What is a good brand for an external filter/pump I can use in my 30G breeder and then in a 100g preformed pond that will only be filled up the first landing (i'm guessing maybe 40 gallons of water will be used). Any help would be appreciated? THANKS!!
