In this video I show one of the (very) limited hidden and unique aquarium filters I have made.
They can be bought here: filterpro.co.uk/filter-kits-8-c.asp
Invisible / Hidden filter for tanks up to 100 litres (or as an additional filter to reduce nitrate)
This filter is made from the 'Okiishi' OR/5 resin rock which is 46x24x15cm and contains the following:
NEWA oxygenating water pump (450 lph)
Approx. 1kg of Biogravel in mesh bags
Medium density foam
Coarse density foam
3 x 'S' hooks
Carbon pad (optional use)
Fine pad (optional use)
The Okiishi OR/5 resin rocks were made by Unipac and were recently discontinued due to the high production costs.
Total cost for everything included would be well over £100 but we are selling a limited amount (9) of this a ready-made filter for under £100.
The 'S' hooks can be bent to allow for thicker / thinner tanks to get a close fit between filter and glass.
For buyers outside the UK please bear in mind the pump is 240V and to use it from a domestic 110V system you will need a step up / down converter plug or transformer.
