Thanks Mr. Salty, Sometimes I could smack these lfs, they take such advantage of newbies, this doctor contacted these people to setup and maintain this tank, 180gal, it has been up for only 2 1/2weeks, we stoped at this lfs on the way home from the hospital and the owner seen our address on my check and started bragging about putting this tank up, he said we should stop in and look at it, fixit stoped by yesterday and OMG, they have 3 yellow tangs and several clownfish in it, all have finrot and ick, fixit about flipped, he had the doctor and everyone out there in the waiting room, telling them this was not going to work, the doctor doesn't know anything about this hobby, nothing! The lfs didn't even have them feeding anything but brineshrimp...Fixit sat for about an hour telling him what he need to do, get rid of the fish,let the tank cycle,etc...They won't be able to get rid of the fish til next week so fixit went over there today with some Formula One and algea sheets for the tangs. This guy has about $8000 tide up into this, he has asked fixit to take over the care of it for him. We plan on opening a petshop with a service for people that want saltwater but might need a little help, so this is a way to start I guess. It gave fixitsomething to look forward to and put a little bounce back into his step. I think this was sent from heaven...The doctor wants anemones, but he only has 250watts on this huge tank, that is why I asked about MHs with acrlic..Thanks for the info...Later Lisa
