So I'm new to the saltwater setting up and need some help. I have a 16 g Fluval Edge Tank and it's been fishless cycling since Monday (4 days). When testing both my nitrite and nitrate are at zero but my ammonia is at around .25 to .5 how do I get this down. Bare with I'm still new with all the fish lingo and what's what. I also have one live rock around 2 lbs 10lbs of live sand and some fake decor. Let me know any advice would be great help
