Pump suggestions

[aquatechy]

Plumb two Mag's in series (one feeding into another), either 7 or 9.5. Same speed, usually 1.5 - 1.8x more pressure. (and don't plumb ANY aquarium pump in parallel ever, they're not designed for that)

In case you don't believe me:

On the other hand, if you want good quality pumps, go for Reeflo Pumps. Reeflo also recommends doing the same thing if you need more pressure. A bit fancy for your use, but reliable. Either way, make sure your plumbing fitting are solid, as higher pressure means even small holes may start dripping.

Is that a typo or are you suggesting you can't plumb pumps in parallel?

It depends on how much water you're moving. A MAG 5 might pump it that high, but how fast? I do 50g changes using a MAG 12 on the same floor, and that makes me impatient.

I was suggesting that AQUARIUM pumps cannot be plumbed in parallel. I have spoken to Reeflo and Iwaki America about this for my previous pumps that I've owned from them, and both have told me that for pumps to run in parallel, they need to have been designed to do so and have to run off a single power source (Reeflo) or a single-phase power supply (Iwaki). Reeflo also stated that most manufacturers of aquarium pumps, themselves included, dont intend their pumps to be used in such a manner.

That being said, the guys over at Iwaki said that the consequence of running aquarium pumps in parallel is just more noise and wear-and-tear on the pump. The only reason I made the above statement is to ensure that someone who's never heard of the concept of pump-linking doesnt use it inappropriately. I appreciate quiet in my house, which is why I went to such lengths to do the research.
