Hi, my fish tank was running with a completely brand new fluval 207 for the past 3 or 4 months. It was making noise for months and it got worse over time. I recently cleaned it up a week ago and now, it leaks when I lean it on on the sides. It's the first time that I had lemon canister filter as I still have my 205 running on my freshwater. I do not have space for a sump. So, how long can my tank run without a filter? Plus, it's making bubbles in my tank that gets into my gha problem.
