Try a Red Sea test kit. I think you're good to go! Excited to see your progress on this tank!Thank you! The Waterbox tanks were my second choice initially. I had my heart set on a Red Sea 250. But the place I wanted to buy it from was always sold out. I actually love this tank, now that I have seen it in person.
My ammonia was at or around 8ppm initially. I will try a couple of snails to see. So far, my 3 hitchhiker snails are moving around and about on day 4 here. So, maybe you’re right, the cycle is complete?
