The professionel 4+ represents the latest evolution in our advanced external filters, showcasing high-quality filtration technology along with integrated features. Its square canister design offers stability and a generous filter volume while being suitable for corner placements and not occupying excessive space. Thanks to the innovative Xtender function, the intervals between filter cleanings can be extended.
Available in three sizes, the professionel 4+ filters cater to aquariums with capacities of up to 250, 350, and 600 liters. Both the 250 and 350 models are offered as thermo filters (T).
These filters are distinguished by their impressive flow capacity and energy efficiency, along with several additional features:
- Self-priming: Eliminate the hassle of complicated suction methods! The self-priming aid prepares the filter system for a quick and effortless start.
- Safety hose adapter: The tap unit includes two hose connectors; for safety, the hose adapter can only be detached when the valves are closed.
- Prefilter: The top prefilter captures larger dirt particles and can be routinely cleaned, which helps extend the maintenance intervals between media cleanings.
- Filter baskets: The individual filter baskets are designed for both biological and mechanical media. They can be easily removed, and their contents can be cleaned using the 'Easy Clean' grid. Simple to take out and easy to maintain.
- βXtenderβ Control Function: If the media (fine filter pad) becomes clogged, the flow rate can be adjusted using the control function. This redirects the water while maintaining biological filtration, allowing you to delay cleaning the filter for a few days.
- Quiet operation: EHEIM's high-performance bearings and ceramic axles ensure smooth, quiet operation, long-lasting performance, and durability.
All professionel filters come ready to connect, including original EHEIM filter media along with all necessary accessories: inlet and outlet pipes, EHEIM quality hose, and setup tools.

Great confidence booster for dad - techniques can be successfully implemented immediately after birth!
Format: Paperback
This is an excellent book! My husband read this book before our baby was born. Although I found a synopsis to be enough for me (no need to read a whole book for five main techniques), as an engineer, he really liked understanding all of the "whys" behind the methods, and understanding the reasoning gave him more empathy for our baby. My husband started implementing the techniques in this book immediately in the hospital right after the birth, and they really worked! It was extremely helpful for his confidence as a dad and for my confidence in him / us as we started the adventure of parenting (especially when I was recovering from childbirth in those early weeks). We have continued using these techniques for months, and they make a huge difference. Sometimes babies get overly tired and don't even know why they are crying anymore, and these techniques help to soothe quickly to get down for a nap. Truly, I do not know where we would be without a good swaddle and turning our baby on his side while swaddled, because he can be losing it completely and then the swaddle / gentle bounce calms him down very quickly. The one thing I wish the book did mention but does not is that it IS possible for a swaddle to be too tight on the legs - the latest research shows that babies need room to bend and straighten their legs for safe growth of their hips, so it's ok to do a fairly tight swaddle such that their arms cannot escape, but there does need to be slack at the feet.

SAVED MY SANITY!!!
Format: Paperback
I don't know why I didn't leave a review on this book as soon as I finished reading it! My daughter was quiet for the first week home from the hospital, but along came week two and around 8 pm one night she began to cry, and this time it was different, we literally could not get her to stop. She cried until around 4 am, and I was terrified that we had a year of colic crying ahead of us, but prayed it was just a fluke and that the next night things would be different. However, 8 pm rolled around, the crying began, and we had a repeat of a night full of inconsolable crying. I had never felt such all encompassing exhaustion in my entire life and I just prayed that there was a book that would have answers for me. So the next morning I took to Amazon and began my search. After reading reviews I decided to give this book a try - the length was perfect, thank you Harvey for getting straight to the point and telling us exactly what we needed to know! I was able to implement the S's the following evening at 8 pm when the crying began and I believed with every fiber of my being that it was going to work - AND IT DID!!! Simulating the womb experience was exactly what my daughter needed to soothe her overstimulated little newborn nervous system and she calmed down in less than a minute and fell into a blissful sleep that lasted until her next feeding, after which we repeated the process and she was asleep again. She was sleeping through the night after a couple of months, and we continued to use Harvey's method until eventually she didn't seem to need it anymore. This book was a lifesaver, I have given it as a gift at every baby shower I've attended since I first discovered it, and I'll continue to give it as long as I live!! This book could just as easily be called Happiest Parents on the Block - I am so very grateful that I found it when I did!

Ignore the sales pitch and absorb the advice
Format: Paperback
I agree with other reviews, great advice but the dr really pushes his products in it. I guess the guys gotta make some money. Worth the read though.
