So I’ve just recently gotten a used 75g for my Bearded Dragon and I was debating on what was the best way on deep cleaning it since there’s a ton of confusing information online saying this is bad but this is good I just really want a definite answer on what I should use, the tank itself looks clean but I don’t want to take any chances since I don’t know where the heck this tank has been previously so if anyone could help me on this one I’d appreciate it, thanks!
