Used tank, preuse care questions???

I just bought a used 80 gal tank off craigslist. The fellow is a long time fish keeper and is just ready to move on. The tank appears to be in great shape. He has a magnum 350, 2 aquaclear 70s, and undergravel filtration as well as a Lifegard ql-8 UV sterilizer. Pictures to follow. Right now It is still in the van and I trying to figure what to do next.

His water was very clear, with a few healthy appearing cichlids. There were a few spots of black algae. We rinsed out the tank with a hose before leaving his house. My question is do I need to do anything further before I bring it in the house.i.e. clean it with bleach or vinegar or something?

I will try to find information on the web, but if you have ideas let me know!

Thanks

So far the advice I have been reading is to be conservative. Clean with water only, clean with baking soda, clean with vinegar. I believe this makes sense.

Will go ahead and wipe with vinegar and bring in, then on to the next step.

I cleaned out the tank with water and baking soda.



Looks a lot better. Now has a spot in the family room. I'm glad I did not use any bleach or otherwise cause mischief. Thank the stars for the internet. What did people do before?

Here is the tank:



Will open a separate build thread to gather assistance in preparation for this tank.

Thank you,
Peter
