Dover are resin decorations for glass turtle tanks, all made from a special non-toxic food-grade resin that does not bleach. Except from Dover Corner model, they are equipped with a submersible pump Smart and consisting of two parts: an upper part removable for cleaning and a lower part which can be fixed to the glass (the use of the acetic silicon BLU 9015 is recommended).
Dover rocks for turtle tanks are complete with holes for water suction and may become efficient filters thanks to the possibility of adding some synthetic fibre Blufibre. Dover are available in six different models included Dover Corner, a specific resin rock which can be positioned in your turtle tank corners.
No problem for maintenance! It is enough to clean the pump rotor every 4-6 months with a soft brush and tepid water.
