We are very new to the fish keeping world. We bought a 28l tabk for my sons birthday and we have 6 neon tetras and a couple of cherry shrimp in there. The ammonia levels are constantly between 0.50-2 0ppm (nitrites 0 and nitrates 5) how can i get this level down? I have been doing approx 30% water change every other day. Would buying a bigger filter, using our exsisting filter media, help?
This is so much harder than i ever thought it would be! Any advice would be greatly appreciated.
