Sad to say another fish died.. my paradise gourami. I am down to 5 fish now. The remaining live fish I have had between 3 months to 2 years and with my old tetra whisper filter before I made the switch. However, the fish that I did add after I made the filter switch to aquaclear, all of them died which i guess now that I read this is not surprising since I threw my tank into another cycle. As for the test kit, is this a good one to use vs the test strips? Amazon.com: API Freshwater Master Test Kit: Pet Supplies
