i agree that vinegar might not get that stuff off, so easily. you probably need the clr. try it. as long as you rinse it off, completely and carefully, it's not going to harm your fish. also, apply lots of "elbow grese."
i bought a pre-owned tank that was also in bad shape. i filled it with soap and water and allowed it to soak it for several days. I then hooked up a hose and started scrubbing with a soft brush. i rinsed it out good and had no problems. i say go with the clr.
i figured it would be the same as coffee pots .. if you rinse it well .. after putting in the water if there would be any left it would be so diluted it would not hurt anything
i just figured the input of others would be nice ..
I recommend you use Muriatic acid at about 1 part per ten. It works very well to remove lime and will destroy any residual organic material. It will not harm silicone or glass.
Make sure you wear goggles and rubber gloves when your handling acid, or a strong dilute solution. Work in a well ventilated area. I've had a lot of success soaking used tanks for 24 hours and then again for 24 hours with tap water to remove residual acid.

yea live in a apt... so i doubt that will happen .. lol .. thanks for the idea . but everything will be done in my kitchen i think i will do it in a Rubbermaid tub let the tanks soak in a CLR and water solution and have a place to scrub them out as well
