Penn-Plax Under Gravel Filter System-For 40-55 Gallon Fish Tanks&Aquariums(Pack 2)

Good

We bought these to put in our 75 gallon tank so that our fancy goldfish had extra filtration. We already use a canister filter for them but I had an extra air pump from when I got an under gravel added on to my 55 tropical tank (because I'd accidentally ordered 2). I use this same brand in that one, as well!The price is awesome and they work amazingly. Helps keep the water oxygenated and they fit perfectly. Once you get your gravel or substrate in you don't even notice them.Also, these don't make noise: whatever noise you hear comes from your air pump, and if the air is too strong or you have a crappy pump, then yes, they're loud-but do it right, with air line adjustable knobs and a good quality pump and you'll have no problem. The lines were great and they gave plenty with the set up to get it up and running! Will be back to buy another one soon since I'm setting up a 3rd tank soon!

Es del tamaño perfecto y con los accesorios necesarios

The media could not be loaded. Back in the 80`s & 90`s, i used to keep fish, but had a break from it till 3 years ago, when i purchased my current setup. Back then, pretty much the only filter system around, was undergravel filters and they always worked great. Nowadays though, with modern systems, undergravel filters sort of died out, or so i thought. I have an Ocellaris 1400UV canister on my tank, which i have to say, does an amazing job, but because i`ve now had the tank 3 years, i decided to do a complete clean out of the tank and i have to say, i was blown away by how much muck was in this tank, especially in the gravel. One of the biggest causes of it, was the volcanic substrate i`d put in the tank when it was first setup, as it worked it`s way through the gravel, it had literally turned into lumps of mud and then along with all the other muck, well, you can imagine. So, after coming across these undergravel filters and the fact you could still buy one, i decided to fit this one to my take, because lets face it, you can`t have enough filtering. It all went together great and the only thing i had to do, was trim about 20mm off the width, because it was slightly wider than the tank (front to back). The kit comes with everything you need, even the air stones, all you need to buy, is the pipework and the air-pump. So far, it`s working great, but it has only been a few days. I`ve uploaded a video to show it working. The tank looks a little yellow/orange, because at the time, my full spectrum light was going into sunset mode, but you can see what you need to :) Great kit, easy to fit and great value as well, certainly worth fitting.

Ich habe mir zwei Packungen bestellt, entsprechend der Aquariengröße zugeschnitten und bin sehr zufrieden. Das Aquarium läuft gut und ist gepflegt wie nie zuvor. Verwende zusätzlich einen Aquarieninnenfilter.Allerdings: Die Filterkartuschen sollten angeblich alle 2 Wochen getauscht werden. Aber wtf kann man die kaufen??? Von Amazon werden sie nicht an meine Wohnadresse geliefert und wären außerdem teurer als das Gesamtset!!! Scherz oder???Fazit: Gutes Produkt aber trotzdem überlegen, wie es dann weitergeht ...
