Eheim Air Pump 400 Lph, 3rd Feb 2015
Reviewer: Niall Gribben
Having recently got back into the great hobby of keeping freshwater fish & plants, I set out to replace some of my equipment.
The Air Pump.
Reading many reviews from multiple sources I decided upon the Eheim 400 Lph.
Got it up and running around 2 weeks ago and boy, what a joy.
Quality & quietness are the two words that would describe it.
The staff at SeaHorse were very knowledgeable about the pumps they stock and after all the information I gleaned while researching this item they answered my question's without hesitation or fault.
Yes, you will get cheaper imports / copies from China and from your local shops or on the web but there will be no comparison when it comes to turning it on.
The 400 model has it all, two separate controllable outlets, comes complete with 2m
of hose and two diffuser's that each have an additional air flow / bubble effect adjustment.
You get what you pay for at the end of the day, why put up with vibration & a background hum. Highly recommended. By the way I have it installed above my aquarium on the wall (easily hung up with the purpose built-in screw holder) for ease in adjusting the control's, so even though it's located outside the aquarium cabinet I find it non-evasive to the ear. Hey, it looks cool too!
