Watch out though on the Aquaclear 70's though the inlet plugs quickly so either run a prefilter on them or use it as your pump to mix your salt or in your fuge. I had them and scrapped them after they burned out after 4 months. I celebrated when the Korillas came out. More flow for not to much more cash and heck 2 of mine are now 3 years old and not one issue except for losing the madnets that mounted them to the outside. Replaced them with a cheap alage magnet from Wal-Mart.
