Hello,
I just recently got a 30g sump with overflow. Now the thing is it come with (2) U-tube going from the overflow box to other. my question is how can I get the U-tube to syphon the water out to the outside box and down to the sump.
any trick with this..can some one guide me step by step. What do I miss or need to do.
Here is a couple of picture how my overflow look like.
