What sits inside your aerate K1 chamber ?

Lots of 2" stones.
Pipe to fit base with mm size holes
9" disk.
5" Japanese Ceramic Air Stones style.

What do you use.

Thanks

Russ.

It's a square chamber so I've got a square loop of speedfit pipe with 1mm holes drilled in it every inch or so. The speedfit pipe is about half the size of the chamber so it sits part way between the outside and middle of the chamber.

Hi Russ,

I have the same as Ed above i use speed-fit pipe with holes i think mine are 2mm and it works a treat
