Anyway I left a small piece of market prawn in the morning till now.
I took out the market prawn to smell, it smell like shit!
But my tank ammonia and nitrite is still undetectable by tetra testkit
I'm wondering should I continue to leave the prawn there.
Using live sand and rock is cycled for 4 weeks. Using nsw... Just feel that if I remove the prawn, my aerobic bacteria will be deny of food source. Ammonia
