Hello friends. A am new in reef aquariums. I have a question. It's already been 10 days since I started the aquarium. There is a shrimp in the aquarium for 8 days, where it has already started to decompose. But still the ammonium test shows no ammonia. At the start of the aquarium, I used aquaforest live sands. I do not use other bacteria. What could be the reason? Or just have to wait?
