At 8:50 PM the main pump was started and the tank went into life. We had a brief scare that the pump was a dud but as it turned out some un-named people forgot to take the seal of the intake before attaching it to the sump. But that was quickly resolved and all went well. no major guisers or waterfalls. Nate and Vince did a great plumbing job. The only issue is micro bubbles since the Euro-reef is so *** kicking and puts out so much volume that even in such a large sump, without baffles, bubbles reach the pump intake. We dialed down the air intake which seemed to help but we may have to create a bubble tower to negate the problem. The lighting is bright! paul did a terrific job on the lighting set-up. Over the weekend, I will situate some more live rock. if anybody wants to contribute live substrate, please let me know.
