A look at my filter - the Eheim professionel4+ 600

One of the most commonly asked questions we get asked in the shop is “what equipment have you got on your tank at home?” and the area that we think is the most important is the filtration.

Everyone will have a difference of opinion when it comes to equipment on aquariums. We will always advise customers on equipment we have either used in the shop or have on our own setups at home.

I have a Juwel Rio 240 at home with African Cichlids, Synodontis Catfish and some gorgeous L-number Pleco. These fish are big and messy so filtration needs to be good.

 

 

For a couple of years I had an AllPondSolutions large external filter bought for me as a birthday present. I had no end of trouble with it. Cleaning was difficult, spare parts very difficult to source and when you read reviews on them it was scary how many leaked.

As my fish were getting bigger, I decided I needed something serous to keep the water clean and more importantly the fish happy.

I spent a lot of time researching filters, looking at the technical specifications, customers reviews and costings. I decided to choose a filter that should last me a lifetime and fit any size aquarium I upgrade to.

I went for an Eheim Professionel4+ 600. It is without doubt the most expensive thing I have put on my aquarium so I was really unsure if all of the good reviews and technical spec could justify the price. But I could not be more happy with it.

It has a total filtering capacity for a fish tank of 600 litres (almost three times what I have) and an output of 1,250 litres an hour. It has four large baskets of biological and mechanical media, a polishing pad and prefilter.

Two baskets are filled with Eheim Mech Pro, ribbed plastic rings designed to strain out the larger particles of waste. Then another two baskets are filled with Eheim Bio Mech and Eheim Substrate Pro, biological media with a huge surface area for optimum biological breakdown of fish waste and organic debris. At the top is a polishing pad and prefilter designed to polish your water for crystal clear results. Once your filter is connected a couple of presses on the large priming button on the top of the unit fills your canister ready to go.

So the filtration side is amazing, and setup is a walk in the park, but without doubt the best feature is how easy it is to clean.

The hoses are disconnected from the top of the unit by the simple flick of a switch and press of a button. Not only does this mean the pipes stay primed (full of water) but it also means that they cannot accidentally come off.  When you disconnect the filter from the pipework, thepipes close so no water leaks onto your floor. For those of you with young children like me you will know what can happen! You can then take the filter away to the sink to be cleaned. Just four clips need lifting and away you go.

Then reconnect the tap, flick your switch and away you go again.

It has a ceramic axle which has been specially designed to run quieter. This filter is like a ninja - you don’t know it’s on!

The final feature, which for my hectic lifestyle is a huge help, is the filters “Extender” function. As I have big, messy fish, the fine pads get clogged quickly. The Extender allows you to control the water flow within the filter to counteract blocked filter media and extend intervals between cleaning. A simple turn of a dial redirects the water around the blocked section so keeping water flow high but maintaining biological filtration.

This really is a fantastic bit of kit and I can say my aquarium has never looked better. Not only will this filter be able to handle a huge fish tank if I ever upgrade, but the build quality is superb and will last for years. Eheim are known for their reliability and longevity. My record is a customer who has had his original filter for over 18 years and it’s still running as well today as the day he bought it.

It’s an old saying but very true in this instance, you get what you pay for!
