I have a 90g in my shed it's been there for 1.5 years it is not an old tank and it never leaked before I will be setting it up in the next month and wanted to know if I put silicone over the old beads would it help at all or is it a waste of time I don't think the tank will leak as is but it has been in storage I will obviously check for leaks before set up but would love just to rebead the joints with out removeING the old silicone just wanted to know if there was no point to doing that or would it actually help

New silicone does not stick very well to old silicone. You would be wasting your time. Storing a tank should not cause it to leak.
How old is the tank? DO NOT rebead it with silicone do it properly strip it and apply. Being that it was in a shed and not a climate controlled environment I would not trust the seals. Humidity in summer and then freezing below temps is not good for them.
If it was my tank I would take my time and reseal it. Beats having 90 gallons on the floor

Storing the tank can cause the seals to go bad. Climate plays a big role. Constriction and expansion with the temps.
It would be a waste of silicone, I personally would reseal the whole 90 thats if it leaked .
You need to strip the old silicone to add more. There are some good youtube videos to show you what you need to strip.
I would water test it for a few days. check for bubbles in the silicone and how easily you can get your finger nail under it.

As others have already stated, new silicone does not bond to old silicone very strongly.
I am highly confident your tank's seal is fine from being in storage. Even with the fluctuation in normal temps, its not an issue. Silicone is designed for exactly the purpose of expansion and contraction......this is why it is used to seal exterior doors and windows for your home, and wood expand/contracts a heck of a lot more than glass. Just set your tank on a level surface using some 2X4 studs or cinder blocks and fill it with water to the top and let it sit their for a week. If there's no leak, after this period, your good to go. No need to strip and reseal.....you may actually be doing more harm than good stripping/resealing for no apparent reason.

If the silicone is hard and you can peal it off the glass with your finger you should reseal the inside of the tank. I have used a tank that was stored for years without resealing maybe I got lucky but knowing what I know now I would have resealed it. It's a few hours work to reseal 90g and 4 dollars for silicone at most
Hey everyone......,. There is no silicone on an acrylic tank. It won't seal. There is a special solvent used to melt acrylic panels together called Weldon. If there is silicone on this tank already, someone tried to fix a leaking tank improperly.
