Rated 4 out of 5 by Oscargirl This product works great
When i first put the ex70 on my tank the water was horribly dirty but within hours of running the water was crystal clear

Rated 2 out of 5 by Brinords Seems to keep water fairly clean but VERY loud
I've had this filter- Tetra Whisper EX 20 for less than 3 months. I've been having intermittent issues where the pump is VERY loud. Make a loud vibrating/humming noise. When it wasn't doing that, it was a great filter. Now it's loud, annoying and irritating! I've attempted to clean it, nothing helps.

Rated 5 out of 5 by Kate20161 Very good
i Have the EX 70 and EX 30 and they are both Very good, nice and quiet! Cartridge changes are made easy with the little door on the lid for the EX 70. The EX 30 is GREAT for my aquarium, the noise is minimal and the water flow is good! same with the EX 70, very good water flow, my water is crystal clear and all water parameters are EXCELLENT! I love the TETRA brand, and if i have a questtion, Tetra always responds in a matter of time, and one time i needed a replacement, and they sent it to me within 3 days and it was PERFECT!! THANK YOU TETRA FOR SUCH A AMAZING PRODUCT!!!!!!!!!!!!

Rated 2 out of 5 by koiwade Not a long term solution
Bought the Whisper EX45 as a primary filter and water agitator for a 40 gallon tank that I use to overwinter my KOI. The filter motor seized and is not repairable. I only use my tank for 3-5 months of the year so I expected years of performance. Very disappointed.
