Hello. Cycling my 75 gallon tank. I put in 2 good size shrimps in a mesh bag. It's been 60 hours (2.5 days) and still no ammonia or nitrite. Shrimps feel like mush and looking decomposed. Is it possible I am not seeing any spike due to the live rock??? I put 3 good size pieces from the local fish shop. Ammonia 0, nitrite 0, nitrate 0. Using Api test kit. Just used red sea test to check ammonia and looks to be 0 as well. Thanks for your input and ideas.
