Hi everyone, I just started cycling a 10 gallon. I ordered the filter (Tetra power 20 Gal) and had the water sitting for a little while because I couldn't figure out what was making the grinding noise ( I fixed it). I added fish food and a small peice of shrimp in two days ago but now the water is SUPER murky and gross. Am I supposed to do a water change or just wait it out? There isn't any ammonia in the tank yet either I tested it this morning.
