My dad recently turned off the electricity in the house while I was away at school to fix some lighting issues. He turned the power back on shortly but since my filter is a HOB, I needed to added water to restart the filter. But I wasn't home and my dad didn't tell me beforehand so the filter was probably out of water for like 4-5 hours.. I'm freaking the f out right now because I'm really worried that all my beneficial bacteria died and my shrimps are swimming around the tank like crazy and they won't stop. I did a 10-15% water change with a capful of Prime and some BorneoWild Shield. Should I be worried? What should I do in addition? Please help. ):
