how to clean an older tank before use????

[dclegern]

Finally bought my 75gal. slightly used!!!
In good shape, but a little (foggy).....just needed a hint on the best way to clean it up.
there's a couple of the foggy patches on it, and just needs general cleaning. But I didn't want to make it worse with one of my own scenarios!!!

anyone!! anyone!!

Vinegar and clean rags is all I have ever used. I'm not sure if there is anything better or not, but I have used this method with reptiles and aquariums for years. I'm new to reef keeping, but I think everyone else uses the same.

X4 on vinegar, when setting up my 150 I filled it and the sump with fresh water and poured two gallons of vinegar, let it run for a a few hours then drained and filled with clean water ran again for 30 mins to make sure all was cleaned. don't know if it was the right ratio but it at the least gave me some peace of mind
