The Iwaki MD-70RLT type aquarium pumps handle back pressure and can be used for almost any application. They are recommended for high-head situations or when using cartridge (pressure) filters. The MD pumps have quality long lasting Japanese motors, which can last up to 20 years or more.
Note: Iwaki MD series pumps do not come with a plug cord tip at the end of the power cord; this is done so these pumps can be universal, being used around the world, where AC/DC variance is allowed.
I recently purchased one of these 70R models, which is spectacular for my 125 gallon reef tank. And my other 70 R model has been running for 16 years on my 90 gallon. I do highly recommend them. Also this is a sweet price, you can find them priced on sale this low anywhere...
