what is the best way to clean a used tank i just recently bought a used 120galon that is pretty dirty how should i go about cleaning it just with water and a few clean rags?
I just bought a used 100g. and that is what I did. I would also recommend you check for leaks prior to setting up. Mine needed a few of the seams redone. Look for silicone that is peeling on the edge or a milky white color.
all the silicone is black in color only seen too little spots that were peeling but i think the should be fine im going to fill it inch by inch the tanks only 2 years old it was filled once then stored in storage for the rest of its life
Rinse it out first...if it still looks bad use a light bleach solution (20 parts water to 1 part bleach) and let it do its work and then rinse over again a few times
Test a few cheap fish on it to make sure its safe (most likely will be) and then you're ready!
Vinegar and water mix will safely clean the tank. Bleach will work if you rinse and dechlorinate well. If it's GLASS a razor blade works great for taking the crud off. That's the route I would go--if it's acrylic DON'T DO THAT! Ha.
