https://www.youtube.com/watch?v=4Ne9bMTN98EI set up my first in home ap recently.now I used 1/2" poly pipe.thats all trhe hardwear store had.so I have the same size fill and drain pipes.i have a ball valve on the fill side.my bed fill time is 5-6 min.
drain time under 1 min.
30 gal. fish tank
2 50lt. beds.
should I try to get 1" drain line.the drainage is very concentrated.
Looks good to me. I've never seen it shown that slow drain VS fast drain makes any difference with respect to plant growth, health of bacteria, fish, etc.
thanks for the reply.the fish seemed a little freaked out at first but have now settled.
