I just set up a second tank as a quarantine tank if I ever need I rather be safe and prepared for future events. Anyway I got a Tetra Whisper EX30 and set it up on the tank. It is making a very loud noise that sounds like maybe something might be lose I the motor or something. I have a Tetra Whisper Ex70 on my main tank and it is very quiet and keeps my tank clean. I was wondering if anyone might know the problem. I have pool filter sand as a substrate in my 20gallon long and yes I rinsed and rinsed till it was clear then rinsed it more after that. I will try to upload a video to let someone see if they can pinpoint the noise. The video I am uploading lets you hear the sound but it doesn't sound 100% like it does in person all the noise from the video comes from the EX30 Whisper on my 20gallon long the EX70 on my 45gallon makes zero noise.
