I Need Some Help...

Hey, i just got the very samething a 20Gallon long that was used as a turtle tank. Just check the seams and make sure they are still in good shape. I am keeping mine in the garage filled up with water for a few days, just to be on the safe side. Whachta going to put in ? I am planning on figure 8's and i am looking for tankmates/bottom crew right now. good luck

I converted a large terrarium for a blue-tongued skink into a big aquarium (100 gal). the tank itself was fine, no burstage. good suggestion, gonecrazy, to try it first without critters.

for safety, tho, you prolly want to sanitize the tank. i use 1:10 bleach solution (1 part bleach to 10 parts water). wouldn't hurt to apply that with a spray bottle, then scrub thoroughly with a sponge or dishwashing brush (i have several devoted to fish-only use). rinse really well with tap water until the bleach smell is gone. a final rinse with dechlorinated water (e.g. tap water conditioner) will also help remove any excess bleach, as bleach is a chlorine compound.

As long as the silicone didn't dry out (like sitting in the cellar for a few years) or wasn't damaged during cleaning you should be fine. Test it for a day or two (FULL) & if no visible signs of moisture you should be off to the races!!
(the reason I say full is to put the max amount of pressure on the seams. If it's gonna fail, you wanna know now!) JMHO Good Luck
