There is no major flow in the tank at the moment. We are water changing from the sump and the tank is looking better than it has in a while, lol..
I use a syringe with a hose tube on it and feed into the urchin. Seems to work quite well actually.
Hubby made a slight calculation error with regards to the size of the holes in the containment area.....or they wouldn't be in there, trust me.
They will be getting a larger urchin made with straws this weekend to give them more room. That one was for the container.
