I picked up a used acrylic frag tank. It has either really caked on salt buildup or possible just bleached coraline with how difficult it has been to remove. I’ve been trying vinegar soaked paper towels but it doesn’t seem to be doing a ton of good. I’m worried about scratching up the tank by scrubbing too much. Any suggestion would be appreciated!
