Im getting an awesome deal on a 90 gal tank from a friend of mine its totally empty just wondering what i could use to clean inside the tank before i start putting stuff in it thanks for the help.

Vinegar and water, anything else will kill the fish.

I got my tank from a friend and was told to use lime away and then flushed it with clean water for about 1/2 hour? Man, I hope this is good!!!!!

[RyanG]

I am not familiar with lime away, you have a link to it?

[Raymond3457]

It is the stuff you would buy at walmart or any other store. Not spicificaly for tanks. clean you bath and tile with it.

[Raymond3457]

I mean I rinsed it with a hose for at least 30 minutes.

I would wash it out with vinegar again then water. Lime a-way isn't nice stuff. It doesn't say that it will be absorbed by your joint glue, which is what I am worried about.

Stay away from Lime-away. It will eat the glue in you joints away. It ate the porceline off my bathtub!
I suggest filling a your tank outside first to be sure it will hold water without leaking. If a used tank has been setting without water, it just may need to be re-sealed before use. I know this from experience.... !

Yeah, don't use the commercial version of Lime-away. It's pretty harsh stuff. I've used a lime-away product made just for aquariums on a freshwater tank and had no problems with it. Cleaned up my tank very nicely (had lots of hard water marks).

Try a mag-float.
