OK all is good. Hubby can help you pull the pump apart if needed. All you have to do is clean the impeller and put it back together. Yes you can get a bag of LS from your LFS. All you need is one bag to seed the sand that you have. That is assuming that you already have enough sand in there to begin with. No you cannot use the sand from your FW tank. That will not have any of the critters that you need for your LS. In fact now is a good time to tell you that SW is really much different from FW. It is harder work and much more expensive. But then it is also much MUCH more fascinating. I just think it is fair to tell you now than for you to put all the time, effort and $$ inot it to find out you don't really like it. Not fair to you or the anilams you put in there.
So assuming that you still want to do SW now is also a good time to tell you there is no absolutley right way to do a SW tank. There a many ways to do a SW tank. It looks like your tank was a Fish only tank. This means that it only had fish in it, basically like a FW tank. This may be because the fish that were in there were aggressive fish or were not reef safe fish. Don't forget that many of the fish sold are predatory, or aggressive, fish. Also some fish love to eat shrimp and will eat any that you put in there. A lion fish is beautiful but it will eat anything that it can get it's mouth around, and the have big mouths.
So onto Fish Only with Live Rock. A FOWLR tank is similar to above but with LR in it oc fourse. Why have LR? Because it can enhance the look of your tank and also is part of the biological filtration like LS. ALthough it hold different organisms than LS and has the purple Coralling algae that is very deisrable in SW tanks.
Then there is a reef tank that is similar to above but with corals in it. This is of course the most fascinating and the most expensive tank. Although I would say it is the most popular tank here. With tis type of tank you really have no idea what you are going to see in your tank next month or 3 months from now. This is the type of tank where people have chairs near the tank so they can sit and star into their tank from inches away to see what is in there.
With that said it is kind of a good idea to try and decide what type of tank you are going to have. For instance you do not want to get a fish that is not reef safe, then decide you want to go with a reef tank.
Well I think I have blabbed enough, plus my wrist is starting to hurt. :scared:
