Hey guys I’m extremely new to keeping saltwater tanks so here’s what I have. Currently running is a 10 gallon with 2 blue devil damsels and 3 hermit crabs it’s been up and running around 3 months. I bought Imagitarium brand Pacific Ocean water and used that for the water and the tank of doing great. However I want to move everyone into my bigger 55 gallon (one day in the future a reef tank) but I have made a couple of mistakes during the cycle first thing was I didn’t have an RO/DI and the silicates in the tap water is keeping nitrites through the roof! Second. I never dosed with ammonia or used anything as a source eventually as time went on ammonia nitrite and nitrate showed up so I didn’t think much of it as I thought this was how the cycle goes. I did a 50% water change and my readings are ammonia .25 nitrite 2-5 ppm the colors are so similar I can’t differentiate. And nitrate 40 ppm I now have an RO/DI and have set it up. My question is should I do another large water change and add ammonia or just a water change?
