RECOMMENDED FORMS Form 24 (ss. 21, 31, 34, and 142) In order to filter aquarium water, it is known that external and internal filters may be used. In this invention, an external biological filter and an under-gravel filter are modified by integrating them into a single filtration system. This system can then remove large amounts of organic waste produced by aquatic turtles more effectively. An external filter is attached to a tubing system, which lies concealed beneath a modified under-gravel filter mat. The tubes are divided into long and short sections to increase the surface area covered in the filtration process. Consequently, waste which would normally have accumulated in the gravel, is sucked through it and the filter mat pores. The dirt is then siphoned from the aquarium to an external filter, where it is filtered by a semi-porous sponge and returned to the aquarium. The TURTLE FILTRATION SYSTEM incorporates a bracketed basking platform as part of its design. The platform maintains optimal filtration levels, and usable space. A light fixture was designed to fit over the basking platform. The external filter is modified to include a water guide and turtle guard. The result of this system is an aquarium that need only be cleaned on an annual basis, with a bi-monthly cleaning of the filter material. The system is therefore low maintenance, hygienic, and cost efficient. Added benefits are that the system is virtually noiseless, escape proof, and aesthetically pleasing.
