Aquarium Advice Apprentice
I recently made a DIY aquarium background and since then all my fish have died, except for 3 ghost shrimp. I thought it had something to do with hard water so I bought a test kit for hardness and a softening pillow. I got the hardness down to normal and all my levels were 0 except for nitrate which was 5. Ph was 7.6. And temp was 77. After the levels had been good for a few days I decided to try again. So I got 3 platys to start with. They acted normal for 2 days and were swimming this morning. Then I come home at noon and they are all dead. Please help me. I don't want to kill anymore fish.
