Pond Filter for Aquarium

Congratulations on your new house and pond! It's great that you're looking to learn more about the existing equipment and make sure it's usable before getting your own fish. I'll do my best to help you with the information you provided.
Based on the dimensions you mentioned, your pond is approximately 5.25 meters long and 2.3 meters wide, with a depth of around 1 meter. This gives you a total volume of approximately 13,000 liters, which is a decent size for keeping koi.
To assess the existing equipment, it would be helpful to know what specific items were left behind. However, I can provide some general guidance.
  1. Filtration: As you mentioned, koi require good filtration. Check if there is a filtration system present in the pond. This might include a filter box, mechanical filtration media (such as foam or brushes), biological filtration media (such as bio balls or bio-foam), and a pump. Assess the condition of these components to ensure they are in working order. If they are in good condition, you may be able to continue using them.
  2. Water Circulation: Adequate water circulation is essential for maintaining water quality and oxygenation. Check if there is a functioning pump in the pond that is providing sufficient water movement. If the pump is operational and meets the needs of your pond size, you can continue using it.
  3. Aeration: Koi ponds often benefit from additional aeration to ensure proper oxygen levels. Look for an aerator or air pump, which can provide bubbles or spray water into the pond. If it's present and working, it will be beneficial for your koi.
  4. Testing Equipment: Consider checking if there are any water testing kits or devices available. These are helpful for monitoring water parameters such as pH, ammonia, nitrite, and nitrate levels.
  5. Additional Considerations: Take note of any other equipment or accessories that were left behind, such as UV clarifiers, skimmers, or waterfalls. Assess their condition and functionality to determine if they can be incorporated into your pond setup.
Given the importance of proper filtration and equipment functionality for koi, it's crucial to ensure everything is in good working condition. If any components are damaged, outdated, or inadequate for your pond's needs, it might be necessary to replace or upgrade them before introducing koi.
Remember, it's always a good idea to consult with local pond experts or professionals who can assess your specific situation, provide personalized advice, and help you create a healthy and thriving pond for your koi.
I hope this information helps you evaluate the existing equipment and get a better understanding of what you have. Best of luck with your new pond!
 
A pond filter system is essential for maintaining clean and healthy water in your pond. It works by removing debris, breaking down harmful substances, and controlling algae growth. Typically, a pond filter system includes mechanical, biological, and sometimes UV filtration to ensure the water stays clear and safe for fish and plants. By keeping the water balanced, a pond filter system helps create a thriving aquatic environment with minimal maintenance.
 
Such great advice. I never knew 600 gallons was equal to 13,000 liters. And now i know i need to keep my water "balanced".

Also i know its a dead thread but there is no vertical head loss, only friction loss from plumbing and the filter itself in a closed loop setup like the OP described. I think a traditional sump or overhead on another floor would be much less efficient for the pump than a closed loop pond/pool filter.

Stingray Biogenetics, pacu mom (and similar) are onto it, methinks: one of the heavy-duty fibreglass sealed drum/pond systems, even one of the retrofit pool systems, as the sealed unit won't suffer head costs (electricity) & overdoing the engineering won't(?) suffer pressure bow-outs. Pool-based pond systems are often kept a distance below & are engineered for it, particularly where you've got infinity spill-over walls etc.
Set plenty of valves & don't forget to close them during maintenance ;)

Edit: oops, yes, I looked-up the "GCTek WattMizer PLUS Systems w/ AlphaONE" & it seem about right.
If you're worried about turnover rates, increase the diameter of the travel-pipe & increase the the filter volume - this will 1) reduce back-pressure to max flow-per-watt, 2) give you more surface area within the filtration to reduce your need for that turnover rate & 3) increase total system volume to, again, reduce the need for that turnover rate. From there you can think about plants, decoration/in-tank filtration, aeration, wave-makers & (under) stocking.
