Why Use an Aquarium Filter?

An aquarium is a “closed” environment. By this we mean that the water in the aquarium is not constantly being replaced as in, for example, a stream or river. Any deterioration in the quality of the water can have a disastrous effect on the livestock in your aquarium. Filtration is essential for healthy fish and plants and a clean and clear aquarium.

For many aquariums, a simple HOB (hang on back) filter will adequately aerate your tank. Many filters have outputs that drop the water into the surface of the tank and, therefore, provide adequate surface agitation. This surface disturbance increases the surface area in contact with the atmosphere and, therefore, increases oxygen absorption. Additionally, the filter circulates the water in your tank which is important because it moves the water at the bottom of your aquarium (water that is not gaining oxygen from the air) to the top surface so it can increase its oxygen concentration.

Filtration Foam Features

Mechanical Filtration

Mechanical filtration is the term used to describe the removal of particulate waste from the aquarium. This includes uneaten food, dead plant matter, fish waste and surfactants such as dust. In the PF filter, the plain foam performs the primary mechanical filtration.

Chemical Filtration

Chemical filtration takes place in the black foam of the filter. This foam is impregnated with carbon. Water is forced through this foam after having been pre-filtered by the plain foam. The carbon will help remove odours, toxic heavy metals and chlorine, water discolouration and unwanted treatments. The carbon foam has a finite life span and should be replaced every 3-6 weeks. The carbon foam must also be removed if treatments are in use, as if present, it will remove these treatments rendering them ineffective. Once the treatments have run their course, the carbon foam should be placed back into the filter.

Biological Filtration

Decaying plant matter, fish food, fish waste and other organics will break down into a highly toxic compound called “ammonia”. If untreated, ammonia is lethal to fish, even in very small concentrations. Fortunately there are naturally occurring bacteria in the aquarium that will break down ammonia into less harmful compounds.

The bacteria (known as Nitrosomonas) require an oxygen-rich environment and a media with a very high surface area in order to flourish. Once they have broken ammonia down into nitrite, a different type of bacteria (nitrobacter) breaks the nitrite down into a compound called nitrate, which is far less harmful to fish. Nitrate content can be kept at safe levels by performing partial water changes (10% every 1-2 weeks). The bacteria mentioned above will thrive on the plain foam(s) included with the PF filter. The plain foam(s) must never be washed in tap water, as this will kill the beneficial bacteria. If it does require rinsing, this should only be done using a bucket of water taken from the aquarium. When you need to replace the foam(s), ensure you do so suing 50% old and 50% new to ensure a continual supply of bacteria. To monitor ammonia, nitrite and nitrate levels in your aquarium, we recommend Interpet’s liquid or tablet test kits.

  • Directional Flow Control -This is achieved by attaching the flow deflector to the outlet nozzle of the PF Mini. Use the flow deflector to push water in the desired direction. Remember that to achieve maximum oxygenation of the water; the flow deflector may be used to push water upwards, thus disturbing the surface of the aquarium.
  • Fixing Bracket - The PF Mini is supplied with an easy to use fixing bracket. The bracket and suckers can be left in place while the filter is removed from the aquarium for cleaning.
  • Maintenance - The Interpet PF Filter has been designed to give high performance with low maintenance, giving you more time to enjoy your aquarium. However, regular maintenance is an essential task if your aquarium fish are to remain healthy. Spare parts, replacement foams and accessories are available for all Interpet PF filters.

Troubleshooting

PF Filter flow rate drops considerably

Check for blockages to the filter inlets. Ensure fibrous material such as plant matter have not formed an obstruction. Remover the foams and clean them if blocked. If the foams have lost their shape, they may be fully blocked and will need replacing. If this does not resolve the flow rate problem, check the impeller.

PF Filter is noisy

The impeller of the pump may need cleaning/replacing. To do this the impeller should be removed. The impeller should be carefully cleaned using a soft cloth. A small brush or cloth may be inserted into the impeller chambers removing any debris inside. Once the impeller has been cleaned the magnet should be inspected for any damage in any way, the impeller should be replaced.

Power cut

Any interruption of more than 2-3 hours of the water supply through the filter will cause the bacteria in the filter to die. Should this occur, do not simply restart the filter. You must thoroughly clean ALL the filter material and start the filter again. In an aquarium fully stocked with fish, this may lead to water quality problems. The filter should be seeded with Interpet Filter Start. Regular checks should be made on the ammonia levels and if they reach detectable levels, we recommend the use of Interpet Ammonia Remover.

Water will not stay crysal clear

If the aquarium does not contain large, messy fish it is recommended that you consider using Interpet’s Filter Aid which clumps together fine particles and allows them to be removed more effectively by the filter foams. Additionally, cut down on feeding levels for two to three days and ensure you regularly perform partial water changes.

Replacement Consumables

After running this filter in my 40 L tank for 2 months I have nothing bad to say against it. It has kept my water crystal clear and has required absolutely zero maintenance. The pump is very quiet when used correctly. If you are finding that is making excessive noise then there are a few very simple things to check before saying "this is s***!" and leaving a one star review:

- Check how low the pump is riding in the water. If it is sitting too high with the venturi valve fully open air bubbles will form inside the impeller outlet and make a bit of a racket. If this happens move the filter down into the water and see if this stops the noise

- Close the venturi valve (the O/I blue switch on the top of the filter), this should stop the noise. Now, slowly open the valve by pushing down on the correct side of the switch until bubbles start to come out. Opening the valve further will cause too much air to enter the impeller outlet and this will make it noisy. You need to get used to how much you can open the valve to allow air in without having it make noise.

Fitted this into a 60 litre tank. Keeps the water crystal clear and is really easy to clean. Not very noisy at all and stays put with the suction pads. You can adjust the flow rate which is quite handy too.

I have a PF2 for my Fish Box 64l and that model has a place for the white foam and the black (carbon) foam as well as for ceramic rings that lets the good bacteria grow. The PF1 is smaller and doesn't allow you to use the rings, so the filtration will not be as good as a system with them (obviously). I would recommend this for a basic tank with perhaps a small fancy goldfish and only if you did weekly 50% water changes on a fully-cycled tank with the properly de-chlorinated water, and if you obviously used a vacuum hose to remove the waste from the gravel/substrate.

This filter will not clean as well as the PF2, so if your aquarium allows in terms of space I would go straight to the PF2, which filters more water per hour.

In terms of construction, the PF1 is nicely built and has the same quality of the PF2, it comes with sucker pads that are removable for cleaning and the filter itself attaches to the aquarium via a plate. This plastic plate contains three holes for the suckers, you attach this to the aquarium and then you lower the filter into it, kind of cradling it into place, which allows you to quickly remove it for cleaning without having to deal with the suckers.

If you make sure that the glass is algae-free and clean when you first install the filter, the suckers will not keep dropping off.

I would recommend the user to clean the white foam every week when doing the water changes because it will get quite nasty with the debris and waste, and gently clean the carbon foam too. Since there is less parts than the PF2, this will be easier to clean so there should be no excuses to let the fish suffer from a poorly maintained filter.

Style Name: PF 2
I've just bought another one of these after the first one died at 3.5 years old, which is probably reasonable for an £18 filter...

Pros:
I've got a 68 litre tropical tank, and this is very efficient at keeping the water very clean.
I use the interpet "filter start" just 1-2 ml into the tank every week which is supposed to keep the biomedia happy.
As others have pointed out, the main carbon and mechanical filters are quite coarse, I have found that adding the superfine thin pads on the carbon side make an enormous difference to the water quality. As I am in Scotland and have very soft water, I found that it tended to go green, but could not use the algae treatments due to pH issues.
The superfine pads completely removed this problem.
It is easy to take apart for cleaning, just make sure you remove it completely from the tank before opening

Cons:
It's pretty huge - 68 litres is absolutely the smallest tank I would put it in if you don't want it to totally dominate the tank.
The sucker-attached bracket that holds it to the tank wall tends to slide gracefully down over time, so if you want the venturi to keep bubbling you need to make sure the bracket does not keep submerging the air intake.

I have a Juwel BioFlow Mini running in my Juwel Korall 60, and it does an ok job but only has a single sponge for filtering. I had a Marina25 running alongside it, but decided to swap it for something new. The PF mini, so far, seems great. My tank always suffered from yellow water, but the PF mini seems to have cleared it already (after about 10 hrs!), maybe due to the carbon filter inside which my other filters don't have?? I got a free sample of water polisher in the box, but haven't tried it yet - I haven't read the booklet fully so not quite sure where to put it.
I have the PF mini sitting quite high so it produces some bubbles on the surface, to allow gas exchange. I think it's quite quiet (I like the sound of trickling water).
For the price, I'm very happy with it.
I also think running 2 filters is a good idea, in case one starts failing, or for during maintenance, you can always have one running...and this only runs at 4w.
