OASE BioMaster Thermo 850 77118 sku-699916737 706759771184

The OASE BioMaster Thermo 850 external filter, model 77118, is an All Fish Tanks and Supplies item with a built-in heater. Its EasyClean pre-filter module can be removed separately, making maintenance simpler, improving filter efficiency and extending the life of the main filter foams. The enclosed heater keeps equipment out of the tank and prevents inhabitants from touching it directly.

It uses bi-metal temperature control, a thermal shutoff and an adjustable range of 66°F to 90°F, with a secondary knob for fine adjustments within +/- 2°F. Sealed 4-stage pathways move water through activated carbon foams, foams of differing pore densities and Hel-X Biomedia, which provides surface area for beneficial bacteria.

Locks on the handle, pre-filter and aquastop help prevent maintenance spills. The detachable aquastop lets you move the filter without disturbing the tubing. Made in Italy with German engineering from OASE, it has a 4-year warranty (3 + 1 year with online registration).

Included are an intake tube with inlet strainer, water distributor nozzle, spray bar, inlet and outlet adapters with flow control, tubing, fittings, a heater adapter and 6 ft power cords, one each for the filter and heater. SKU sku-699916737; UPC 706759771184.
