Works well fits well does the job

I bought the top fin fish tank that comes with one filter. My tanked looked awesome! I switched out some water once a week and really didn’t even want to do a complete clean at 4 weeks because it was sparkling. I do a full clean and replace the filter with one of these. Within a few days it had started to look a little funky and within a week I had to do a complete change. I hoped that filter was a dud and tried a new one. I’m less than 24 hours in and the tank is already showing signs of muck. I’m really disappointed :(
