Something else I like about a lot of these pond filters is that most (not all) now come with a UV clarifier, as shown in the picture above, which helps prevent and remove green water caused by algae. Something that is probably one of the most common issues I see in ponds. Now, I’ve discussed UV clarifiers here where I talk about why I sometimes recommend having separate UV clarifiers. You can use a more powerful model as the ones built into the filter are sometimes a little underpowered, that being said, most are generally good enough. To apply for online finance, you must be over the age of 18, work at least 16 hours a week, or be retired with an income. You must also be a resident of the United Kingdom and have lived in the UK for the last 12 months or more. The UV clarifier light is 5W so a little on the weak side. That being said, it will still kill the green algae and causes it to clump up. The foam filters then trap the clumps, or the clumps fall to the bottom of the pond, out of the way. As a pressurised pond filter, this AllPond Solutions model can handle more water than more conventional gravity-fed filters. It sits on the side of your pond where the filters work alongside the UV steriliser/clarifier to clean your pond water.

The Easyclear 3000 pond filter uses foam filters (coarse and fine) as its mechanical filtration to remove pieces of debris and waste. The Kaldness K2 biomedia is used as the place where good bacteria are encouraged to grow to break down organic pond waste. Credit scoring is the process used by financial services companies to evaluate the credit risk of new applicants. This technique will be applied to your application for online finance. Credit scoring works by awarding points for each answer given on the application form such as age, income and occupation, together with information obtained from credit reference agencies. The filter box has both mechanical and biological filters in it. The mechanical filters are Japanese matting and has both coarse and fine grade filters, while the biological filter is bio balls. It is all pretty standard stuff but good enough to get your water filtered and clean. This filter comes without a pump. And a downside, though not a deal breaker, is that it also comes without hoses. This is fine as you can choose your own pump or you might already have one anyway. Just make sure it’s the right size pump. Once the water is through the first foam, depending on the model you have bought (In the below picture I am showing the EasyClear 6000) there will be stones. The primary purpose of these is to act as a buoyancy aid for the unit, but they will also add surface area in which bacteria will cultivate. As well as this, the stones have the added benefit of trapping any solids. So it really is up to you if you want to rinse them out while cleaning the system.

As the dirty water flows into the filtration system, it first encounters the coarse pads that take out the bigger sediments and stuff, and then the fine pads that take out the smaller bits. The pump has a 2,300L flow rate and you know that it works perfectly with the other two pond cleaning appliances. The UV clarifier is a must and this one comes with a 9W bulb. All three pond cleaning units are designed for small ponds, that’s those up to 6,000L with no fish but the unit will be suitable for smaller ponds with fish. ( See the Buyer’s Guide for an explanation of how this volume changes with fish or sun). The Blagdon 9W 12000L Minipond 6-Stage Box Filter uses mechanical, biological, and chemical filters to clean and polish the water flowing through it. I like that the three sizes of hose fittings mean that it fits into most standard pond filtration systems so fitting yours be fairly straightforward. For example, the Blagdon model in this article does clean a 12,000L pond but one that has no fish, is in shade, and is deeper than 75cm. Just add some fish and the volume of water that can be cleaned goes down to 6,000L. Working out the correct size The Fish Mate 15000 Pressurised Bio Pond Filter with Powerclenz is a great alternative to a filter box. It doesn’t come with a pump or a UV clarifier light so you may need a separate UV clarifier, however, most filters don’t come with a pump anyway unless you go down the all-in-one filter route. Its three hose adaptor sizes allow it to fit into most pond filtration systems that already have these other pond appliances installed, so it should be fairly straightforward to install.

Pros

This pond filter unit is compact and discrete and won’t stand out if you situate it on the pond floor.

Basically, the size of the pond most filters are recommended for can be as much as half if you have fish and your pond is in the sun. So, a filter of 12,000 litres might only really be suitable for a 6000 litre pond if it has a lot of fish and is in the sun. They also sell smaller and larger models, so you will be able to select the right model that will be better for your pond.

You know when it’s time to clean the filters as there’s a float mechanism that raises up when the filters are dirty. And the cleaning task is easy as you just turn a handle on the top of the box. This lets water in to rinse the sponges inside; you don’t have to open the box to do the cleaning. However, some online reviewers report that this cleaning operation has been hit or miss for them. The dirty water from this process exits the filter via a separate outlet to the clean water. Pros A pond filter box is a necessity no matter how small or large your garden pond is. Sunlight encourages green algae to grow, fish always produce waste, and who knows what garden matter and debris will find its way into the pond. Keeping your pond water clear and sparkling enhances your enjoyment of the pond and creates an enticing habitat for all manner of wildlife. The sizes are based on ponds without any fish, so please bare this in mind when selecting a pump/filtration system that is right for you. Please take a look at the chart for a better idea of which size EasyClear is right for your pond. The Fish Mate 15000 Pressurised Bio Pond Filter with Powerclenz is a good choice of a pressurised style filter box if you already have everything else you need to clean your pond water (pump; UV clarifier). The three hose adaptor sizes let you fit this to the hoses of most filtration systems. And the automatic cleaning features reduce this chore to the minimum so this is a feature that is very useful, making cleaning and maintenance much easier.

The depth of the pond, whether it sits in sunlight or shade, and the number of fish you have in there all affect the production of green algae and waste which the filtration system is set to clean. The shallower the pond and the more sun and fish, the smaller the volume of water and hence the size of the pond that any given model can handle. Some pond filters come with a built-in pond clarifier. This is a UV light that kills the green algae in the water. The algae then drop down to the bottom of the pond and remain in the water and are caught by the filters as waste the next time through the filtration system. Within minutes of your application being approved, you will be presented with the options to either e-sign or print and return your finance agreement. As the pump and filter are all contained in one unit it means that there will be no need for pipes coming out of the water unless you want to feed a waterfall instead of using your fountain-head which is very simple to set up. This is a pressurised pond filter in a canister-shaped receptacle. This means that you can install it either above or below ground, which is one of the main advantages because it makes it easier to hide. It uses foam filters for mechanical filtration and a SUPRA+ bio media to encourage good bacteria to grow for biological filtration, something which is a must for healthy water. The single clamp on the lid lets you remove it for easy access to the filters for replacing them.The high performance pump is super efficient and has designed to last for years to come. It can be used to create a decorative fountain or waterfall in the pond. Two gauges are in the lid of the filter box. One tells you the temperature with the box and the other is an indicator that the filters are dirty and need cleaning or changing so this is a nice feature that not all filters have. There’s also a viewing window so you can see that the UVC light is working properly. The EasyClear 3000 and 4500 have a maximum flow rate of 1260 lph and include a fountainhead to produce a fountain. Suitable for ponds between 3000-4500 litres in size or fish ponds between 1500-3000 litres in size, they’re the ideal pond pump and filter combination for a small pond. For a great price, you get three great features - a pump, a filter, and a fountain. The filter sieves out solids that make the water cloudy and makes the water healthy for fish and plants.
