r/Koi

Things are looking up. He spent about 8 hours laying on the bottom of the tank last night but today he's able to stay oriented in the water and is even showing some signs of grazing behavior. Still super weak and spends a lot of time on the bottom but not dead so that's a win.

Still curious about this fin growth if anyone has any ideas.

Hi
I have a poorly shiny orange Koi. It started around 7-10 days ago when I noticed the dark mark marks above his eyes. The last few days he has been sitting on the bottom more, clamped fins and flashing a few times in a row. He still comes up for food, swims a little but is not hanging around with the other fish very much.

I’m new to all this so any help or guidance would be greatly appreciated!

Thanks

I just love how they all follow me around 🥰

Hi,

I'm building a DIY aquaponics/pond filtration system and can't figure out this problem.

From right to left: a 600L radial flow filter (RFF), a 300L moving bed with K1, and three IBC bog filters.

Flow is:

Pond → 14,000 L/h pump → RFF → Moving Bed → Bog filters → Pond

The RFF and moving bed are connected with 2 × 63mm pipes. The moving bed also drains through 2 × 63mm pipes and maintains a perfect water level about 20cm below the top.

However, as soon as I turn the pump on, the RFF fills completely and overflows, while the moving bed level stays fine. If I seal the RFF airtight, pressure builds and it works, but obviously that's not how I want it to operate.

The RFF → moving bed pipes have a couple of 90° bends and drop about 50cm.

Why can't the RFF gravity-feed the moving bed fast enough when the moving bed itself drains perfectly through the same 2 × 63mm pipe size?

Thanks in advance,

Dwayne

Hey everyone!

My partner and I recently bought a house and the previous owners left this gorgeous Koi pond setup in the backyard along with the water conditioners, food, and spare filters. I noticed this morning, the water levels have dropped significantly and I’m wondering what the best way to fill it back is? Should I use a bucket and pre mix the water conditioner or can I just fill the pond with the hose directly then add conditioner after?

Thanks in advance for the help and here’s a pic of our lil tank 🫶🏼
