Multiple AL 7m from pond + discharge 40cm below water level

Post by slk »

Hi,

Maybe this helps someone.

My 6x AL are 7 meteres away from pond. This is also unusual desing because of using 2x 30 bends - AL discharge is 40 cm below water level. Also all the feeding pipes from POND (BD + SKIMMERS) to FILTER have many bends. So there is a lot of head.

There was no other option to run it.

I have tested below AIR PUMPS:
- SECOCH JDK-30 - not enough water flow
- SECOCH JDK-40 - better but also not enough to get 100 m3/h via 6x AL
- JECOD / JEBAO PA-60 - it was ok at the beggining, total flow was about 100 m3/h (about 180W total) but after two months it started to deliver less and less water, I do not know why. Maybe airpumps have worn out?

So finaly I have installed SECHOCH JDK-S-80 - 5 of them. Now the total flow is asbout 100 m3/h (about 250W) via 5 AL.

All the info about my pond is here - https://www.koiforum.uk/pond-constructi ... 90-m3.html

If someone needs any aditional info pls let me know.

I have converted all the AL to protein skimmers - works really well - dirty water at the end.

Hey SLK,

Thanks for sharing, looks really interesting.
I had a quick look but I'll leave a proper reply later when I have time.
Your setup looks great!
