Heading out of town for a couple of weeks. I have my oldest daughter looking after the system. Now I asked a couple of fellow reefers if she could call them if she had problems. DAY 1!! my clown tank decided that after being absolutely trouble free since the day it went on line that it needed to clog and overfill. DAY 1! it was unbelievable. David was one of the two people I asked, ArstenA, was the other (thank you Brian!) My daughter called David late last night. David was at my house until past midnight fixing the problem. PAST MIDNIGHT! If there is an award for reefers who go above and beyond the call of duty Mr David Grigor should not only receive that award it should be named after him. I owe you dinner big time David. THANK YOU!!!! To top it all off... We get to LA last night and our flight to Brisbane was canceled until 4PM today had we known I would have been there for the problem last night..
