● Air Pump Type Aji Cooler Included: Shimano Fixcel Light NF-422V 22L White or Gray Self-made air lift protein skimmer x 2 Mame Design Wood Stone x 2 2-way splitter Stainless steel fittings x 2 Can be used if you have an air pump and underwater light. Air pump, underwater light, and piton fixing screws are not included, so they can be added as options. ⭕️ Expand the fittings included with your pump and hook them onto the stainless steel fittings, then attach Velcro to the bottom of the pump to secure it. When you want to put in a lot of horse mackerel, when the horse mackerel get bigger, or when the water temperature rises, or in a car where it's difficult to manage, there is a risk of oxygen deficiency. ⭕️ The hose from the air pump is split into two inside the cooler, allowing you to adjust whether to send air to the skimmer side or directly to the ceramic stone side for aeration. The pump and ceramic stones in the photos are not included. ⚫️ When you arrive at the fishing spot, switching both to the skimmers will quickly eliminate the bubbles. ⚫️ Options ⚫︎ Mame Design Wood Stone 2 for 1400 yen (currently a gift) ⚫︎ Piton fixing screws, 2 for a set 1000 yen ⚫︎ Underwater light, uses AA batteries (Constant white light) with suction cup 2000 yen If you put in a lot of horse mackerel, it will be in the shade, so two are better to prevent them from thrashing around. ⚫︎ I will change the price, so if you want any options, please write your desired options in the comment section before purchasing. Double-opening type that can be opened and closed from left and right. One-touch water faucet that allows you to drain water without getting your hands wet. The protein skimmer removes the waste from the horse mackerel outside the cooler. When you fold down the handle, the wastewater drain hose will bend, so remove the hose from the top of the handle (photo 4). Includes a pet bottle cap for draining in the car. 2L pet bottles are safe. Please transport it in a container such as a garment box while moving it in the car. An instruction manual with simple usage and care instructions will be included when shipped. I made it as carefully as possible, but it's all homemade as a hobby, so there may be small scratches and plastic burrs. Please understand this before purchasing. Aji Cooler Aji Live Bait Cooler
