Hi all, Looking for some advice. The tank is new about 2 weeks and the chemistry seems all within spec apart from ammonia levels of around 7ppm. From what I can gather it's still cycling, just concerned that it's high. What's the best way forward, small water changes or a larger water change, adding some good bacteria such as additives, waiting it out, or any other ideas you could point me towards. A bit about the tank it's substrate is a calgrit and river sand mix, 6ft tank with about a 550gph bio filter, however I think the biggest downside that's created my problem is feeding in the main tank and allowing a bit of waste to build up. It holds 4 very small Murray River turtles. Open to all advice.
