what kind of pumps do you guys use? right now im using laguna pumps which is ok but loses power fast as the head height increses. i have rio pumps for the aquarium would they work ok in ponds? their quality dosent seem good enough for all the algae and stuff they might encounter but 2 rio 2100s looks good only 25 watts each and they pump 600GPH at 2 feet. but i just saw a site selling nautilus pumps a nautilus 30 pump is good for 1100 GPH at 3 feet. it uses only 70 watts and has a 3 year warranty. any brands that are recommended. not sure how big the pond is going to be but imma need 1000-1500 gph at 2-3 feet. Power usage is important since this going to be for a 3rd pond and its going to accompany about 3000 gph worth of pumps in the house. john
