old 29 gallon craigslist. Reseal?

So I picked up a 29 gallon with a really nice stand for $50 off of craigslist last night. The stand is really nice, but the tank is pretty old, it was built in 1994, the sticker is still on it haha. Does anyone have experience resealing a tank? Is it risky or is it something that if you do it right, it should be fine? Should I even use this tank? I am a little worried so I thought that I would ask. I'll prob work on resealing it tonight if its safe and effective.

I bought a used 29 gal tank in 1997 and am still using it today with no problem. It has never leaked or anything else.

Fill it up with water and see how it holds. As long as it's holding water and the seals don't feel dry and brittle you should be fine. Resealing it certainly can't hurt if you know what you are doing.

Resealing doesn't mean just running a bead of silicone over the seam that is already there, just in case there was any confusion. You would actually have to strip all the previous silicone off and start from scratch. I have not ventured into that aspect of tank keeping because personally I don't trust myself. I'd rather buy it from someone else who I can blame when/if it ever fails...

Like everyone else said though, if it holds without leaking any water, you're usually good. Look at the seams head on and make sure there is little to no air bubbles in the silicone. It should be clean, even, and relatively clear.

^ This. All my tanks are used, take it out side on a nice dry day, fill'er up, check for leaks (let it sit for a few hours filled), if none you are good to go. If you see leaks then reseal.

Yes I know that I would be stripping the old silicone off of the seams. but I wouldn't mess with the stuff inside of the seams that holds the glass together. I just don't though, hell the tank is 17 years old... I may buy a new one. Decisions decisions.

Also I got a jebo/Odessea 4 canister filter for 20 bucks. its rated at like 310 gph haha is this absurd for a 29 of could I just do a spray bar and be okay?

The strength of the tank is at those glass-to-glass seams and not the corner bead seen in some production tanks.

I reseal all my used tanks (even tanks I tear down and plan on setting back up within a week). I would rather have a brand new seal for the long haul than an old one. I've seen tanks pass a water test only to fail a week later. a 5 dollar tube of silicone is a heck of a lot cheaper than flora, faun, and whatever incidental damage may arise.
