20g question

I have a 20g tank sitting in my basement, however, it had a guinea pig in it. I was going to see if there was anyway to clean it enough to make a marine tank? If so, how would I go about cleaning it good enough?

 

I wouldnt use any type of chemicals for any tank cleanings. I would fill it up with warm water and let it sit, then take a non abrassive pad and scrub it out. and rinse with clean water

 

Take some able salt to scour it then a good rinse then a gallon of bleach to up under and around the top rim let it set and dump then rinse

 

Is bleach a good idea?

 

I wouldnt never think about using bleach in my tank. But im sure he knows a thing or two about aquariums being since he is a sponser with over 4k posts.

 

I have used it numerous times on tank stuff. I even cook all my LR in it. Rinse and let dry. That is how I cleaned my 265g when I brought it home. Put straight bleach in a spray bottle and went to town. Do like Tangster said, get up under the rim real good.

 

As long as it is properly cleaned, like Tang said, AND the tank is suitable for aquarium use, then it is safe. Glass tanks used for retiles and rodents are generally not built with the same sealants as marine aquariums and will bust at the corners when the pressure of the water is added. Test the tank outside in the grass just in case it breaks. You don't want that in the house obviously. Personally, I would fill it up completely with water and let it sit outside for at least a week before calling it "safe enough."

 

Yeah it was an aquarium that we bought for the guinea pig, so its made for fish.
