I just bought two Hydor Koralia 1 pumps. They work great, but I found the power cords are way too short for a deep tank. Definite con. I'll have to purchase extension cords to run them in my 31" deep tank. On sale for $28.99 each at Petsolutions.comLord Barium;1927762; said:Hydor Koralia Water Circulation Pumps
Pros: Doesn't generate any heat, powerful, quiet, scatters water instead of blasting it in one small area.
Cost: fron 35$-80$ (also depends on where you buy it)

I'm not sure how I feel about the clear plastic mounting legs, but they are very effective and very sturdy. I'm thinking of painting them black but i'm not sure yet.
