(Filters page is currently under construction and we have information on dozens of filters to add to it - please let us know if any links below are incorrect)

This page has lots of notes on various types of filters - search by manufacturer and any model we have notes on will be displayed, helping you to understand your filter better.
There will be notes on the best type of media to use in the filter as well as how much the filter (or part of filter) will hold, water flow direction and the best layout for foams, biological media and any chemical media used.
Links will also be given if you want to buy filters.

This page also has links to any videos we have made on specific filters as part of the 'Pimp my Filter' videos series on the Pondguru Youtube channel. If the manufacturers have good videos on their filters they will also be linked - please advise us of any broken links.

The figures given below for 'MAX. TANK SIZE' is based on the filter being able to achieve a FULL CYCLE which is the reduction of Ammonia, Nitrite AND Nitrate so they will not match the manufacturers 'for aquariums up to' figure - we only deal in proper filtration and aim to set filters up for a full cycle, not half a job where Nitrates are out of control.
The amount of media any filter will hold are based on it being unmodified and without using a 'booster' or extra filter on the intake to free up any trays. If a booster filter is used on a canister filter it can free up the tray which would have been used for the foams and fine pad.

1.2 litre and 2.3 litre booster filters

We sell FILTER UPGRADE KITS in various sizes which contain the necessary filter media, coarse and medium grade foams, fine pad and filter starter balls to upgrade filters of many types (see below).

Please advise us if any of the information below is not correct - we try our best to keep up to date with the filters available around the world and much of the information has been kindly given to us by people who have set up their own filters using our products.

Feel free to share this information or links to videos with anyone you think may benefit from seeing it.
