Large breeding tanks for ornamental fish, from 800L to 80L, plus other pumps, filters, etc.

This is a listing for FRP ponds and tanks previously used for outdoor ornamental fish keeping.
We paused operations for two seasons due to changes in our breeding facility, and have decided not to use them this season either, hence this sale.
The items included are:
800L (Blue: 109x165x60 cm, crack on the rim, no water leakage)
500L (Orange Large: 90x149x42 cm)
200L (Green FRP: 75x120x25 cm) x 2 units
180L (Blue: 66x100x29 cm) x 4 units
180L (Orange Small: 67x96x34 cm)
80L (Green x 2 units, Black x 2 units: 55x85x19 cm)
3 x 200L DIY Poly drum tanks for water storage
Electric pump used for water changes
Blower for aeration
2 x Water cleaners for outdoor ponds (with repair marks)
DIY PVC pipe air piping for blower (may not have all parts, considered a bonus)
Small items such as air valves
Several DIY bird repellent nets
We will include 10 packs of frozen brine shrimp if you pick up the items or if we deliver them.
All items have been tested and are confirmed to be working. They cannot be sold separately.
These items were used in a greenhouse for several years and did not leak water, but they do have scratches, dirt, and tape marks from insulation.
As we do not currently have access to water, we can only wipe them down with a bucket and cloth before shipping. Please understand this in advance.
The dimensions in parentheses are the largest internal measurements, all in cm.
Please note that there may be slight errors as measurements were taken with a scale.
Shipping will be cash on delivery. We will try our best to accommodate your preferred shipping company, but due to the large size of the items, delivery to the entrance of a private residence may not be possible. You may also be told that the shipping cost cannot be determined until pickup. Alternatively, if our schedules align and the distance is within approximately 400km one way, we can transport the items ourselves for the round-trip highway tolls and fuel costs. In this case, calculations will be based on departure from Omagari IC on the Akita Expressway. If you are interested, please contact us via comment in advance.
We do not intend to charge any additional fees such as commissions or meal expenses, but please arrange for someone to help with unloading. Of course, you are welcome to pick up the items if our schedules match, and we are considering a discount of about 5%. However, it may be difficult to load all items onto a light truck.
Also, please be aware that these items are listed on other sites, so they may be removed suddenly.
Thank you for your understanding. Please feel free to ask any questions.
