I just got my first Salt Water aquarium from a friend at work and I’m starting to set it all up. The aquarium had gotten “out of balance” (infested with creepy bristle worms) so I needed to completely empty the tank, throw out the substrate, sun bleach the rocks and start all over.
I’ve had fresh water tanks since I was a kid, but I’ve never had salt. It’s a whole different world, so I felt like I needed a lot of help and advice. Of course, I went to PETCO to buy all the things I needed. I bought new substrate (aka crushed coral sand), salt and a filter refill.
