Thank you for viewing. This is an external filter for an aquarium. It was used in the aquarium shown in the last photo. Since it was used in a saltwater fish tank with powder sand as the substrate, some powder sand may be inside the filter, but it does not affect the operation. Please understand that this is a USED item before purchasing. No claims and no returns, please. ◆ About the product for sale ・Main body and motor head: [Used] (No filter media included.) ・Hoses and taps: [New] (I have kept them at home as a backup in case of failure, so I have not opened them from the bag.) ※ The current Kotobuki Power Box, which is sold new, has been updated. I think it is equivalent to the current "V1500" in performance. There is a "V1200" below it, but although the number suggests it is equivalent, it seems to be equivalent to the former SV900. ◆ Reason for selling I live on the second floor of a two-family house, but I have decided to stop keeping three saltwater fish tanks (reference: the last photo) due to concerns about the Nankai Trough earthquake. If the tanks on the second floor were to fall in an earthquake, it would cause significant flooding not only on the second floor but also on the first floor. I gave the living creatures to an acquaintance, and this led to this sale. I am also selling other filters (Kotobuki SV900X), protein skimmers, filter media, UV sterilizers, etc. ◆ About shipping ・We will ship within 24 hours in principle. ・Rarely, it may take about 48 hours if I have a business trip. ◆ Available for immediate delivery.
