I would do a search for aquarium clubs in your area. If you post on a decent one Im sure someone would come over and help you get your tank going. Im with the above poster,I dont believe that pump is really broken,by the look of the sump(the tank under the tank) Id say it just needs a good cleaning,Ive seen Mag pumps run for ten years and still run. I know I couldnt wait until tuesday to get that sump going especially with all of the debris in the tank. If you do get the pump(its called a submersible return pump)running then before you do ANYTHING,clean all that crap out of the sump,take it outside and use the hose on it but NO SOAP. You dont have to go buy the exact pump if you cant get it running,just about any of them will work as long as you have an adaptor that will fit your hose,but you need to get a decent size one,you can take your hose with you buy a pump and go to Lowes and they can get the right adaptor for you,dont glue the adaptor to the pump,a few wraps of teflon tape will hold it fine.When you clean out the sump get rid of everything in it(bioballs,filter pads...). I have a similar sump and I use one fiter pad right above where the bioballs are,I change mine once every 3-4 days,you will want to change yours everyday for several days,they are very inexpensive,until a lot of the gunk is cleaned out. Now they probably wont have filters that fit your sump but you can buy it in a roll and use scissors to make the pads. The purple stuff is coraline algae and it is very desirable on your rockwork. Look through your rocks and find a few decent size pieces that dont have much/any coraline on them,break them apart with a hammer and put, them in your sump where the bioballs are now,or use little pieces,the more the merrier,my sump is stuffed with rubble. When you decide to start stacking your rockwork try and leave spaces in between the rocks for good flow throughout as well as giving your creatures places to hide,also stack your rocks with the algae covered areas showing so they are exposed to light. If all else fails with the pump you can use one of the powerheads in your tank. Just take it out of the tank and get an adaptor from hardware to fit your hose or make your hose fit it,it can be done for a dollar or two,stick it in the sump and it will move water,enough to get you by. You really have had a bomb dropped on you thesethings are far removed from goldfish/guppy tanks,they require an extreme amount of time and a lot of money. It is truly a wonderful hobby/addiction/sickness,and it isnt for everyone. If you dont think its for you at least get the fish and other creatures to a fish store,the damsels are a dime a dozen,and if you intend to tough it out and stay in the tank I would go ahead and take them out right away,the fish store may give you some credit for them. It looks like you have at least one coral or anemone in there there may be more that are just closed up because of the difficult conditions,if so they probaly wont make it til tuesday without some filtration and those are the coveted items in this hobby,well I hope I helped ya out some and good luck :/
