I have a 1.5 gallon (5.7 liters) acrylic aquarium which I recently made the mistake of cleaning with a blue scotchbrite sponge - not a wise idea, I know, but I didn't realize that the sponges contained harmful chemicals at the time.
Now I'm trying to undo what I did and remove all traces of harmful chemicals from the tank. I was told on another forum that acrylic tanks were more likely to retain chemicals because they're more porous than glass.
What should I do? Would soaking the tank in vinegar help? If so, how should I do that (what concentration and for how long)? Any other suggestions?
I've already rinsed my tank pretty thoroughly and am currently soaking it in water and Bettasafe, which is supposed to remove heavy metals. I have no fish in the tank at the moment. Thanks for any help!
