I have a new tank, 20 gallon. My stock is slowly dying off!! All of my original fish are doing fine! But my mollies and platies are sick! I bought API TRIPLE SULFA. It tells me to take the filters out( I'm running penguin 100 & 150 with 3 filter cartridges combined). When I take them out should I use some tank water to keep the BB safe? My cycle is not over !
