Hello. There are a few changes I have made that to my setup that a likely to cause problems but I’m trying to narrow them down. I recently rescaped my tank and treated the Cyanobacteria with hydrogen peroxide after temporarily removing all shrimp, fish and filter sponges. Since then I have changed my water conditioner to api stress coat from seacheam prime. I have added api fast filter bacteria booster at each water change as I know that the cycle is disrupted. The deaths are all occurring on the hours following the water changes. I will stop adding the bacteria. Can stress coat kill shrimp? Is seacheam prime safer?
