How many gallons an hour does the 60 pump
Answer by ChewyApr 29, 2020
The size 10-20 pumps 105 gallons per hour, the size 10-30 pumps 145 gallons per hour, the size 20-40 pumps 210 gallons per hour and the size 30-60 pumps 330 gallons per hour.

Does this item have the option to adjust the flow? I know betta fish don't like a strong current in their aquarium and I'm looking for a good one for my new 10 gallon aquarium.
Answer by ChewyMay 18, 2021
The Whisper 20, 30, 40 and 60 all have a flow control on the intake tube. Turn the knob backwards so the point faces the wall. You can also place plants in front of the intake tube to help the fish deal with the current.

Is there a power supply included with this filter?
Answer by ChewyNov 30, 2022
This filter does not include a power supply. The filter will require for it to be plugged in to a standard US outlet.

Does this need to be primed after a power outage or is it self priming after power is interrupted?
Answer by ChewySep 27, 2022
These filters will self-prime as long as there isn’t any damage to them when the power comes back on (we recommend power strips with surge protection) and they are maintained regularly. If the impeller or motor aren’t cleaned often enough they could be too clogged to bring the water back up. Also, the water level in the tank is important. It should be no more than an inch or two from the top of the tank for the best and most efficient filtration.

Doubt it’s a whisper

Just got it to replace a store brand filter. The store brand filter was quiet. This has an annoying decibel with constant whirr grind. This is an old school device no new technology involved. Very disappointed in the purchase. Despite the sale price which led me to the purchase, I do regret the purchase.

Garbage filter

I ordered this filter almost 3 weeks ago and it is only working maybe half the time. The motor quits working constantly and it shuts down.

Think twice before buying

I bought this to replace an Aqueon that stopped working after about a year. This was easy to set up, and does a great job filtering the water. The major problem is the noise. I never thought such a small filter could make so much noise. I can hear it over the window a/c. Very disappointed.

Works well, but not quiet.

A great working filter, and filters are very reasonable. However, if you need a super quiet filter, go for another one. With tank in a bedroom, would be annoying.

Good filter

I’ve owned aquariums for the past 20 years, and I’ve always used Whisper filter systems, they last years, work great, and keep the water crystal clear. My fish: Marigold, Marble, Paprika, Sage, Lemonade, Coco, Creamsicle, Maple & Tiramisu are healthy and happy. I downgraded my tank from a 55 gal. To a 30 but I still use the dual filter system because I like to change the cartridge one at a time to keep the good bacteria going at all times. The water is always crystal clear!

Good but.....

Replaced a previous Whisper filter that was probably 20+ years old. This new one works great but it is considerably noisier than the old one. That said, the filter works great, is easy to maintain and would recommend it over the Aqueon which is VERY noisy.

No thank you.

"Whisper" is just a name. This filter makes a grinding sound louder than any other filter I have ever bought, and we have 7 tanks both saltwater and fresh. We know filters. We can hear it all the way down a long hallway from the living room. Followed all instructions. Would not buy again, and do not recommend it. We unplugged it after a day and will only use it again if we are in a pinch. I understand why is it cheaper than others.

Whisper... hahaha not! More like Grinder

So these filters are so NOT what they used to be. I replaced my old filter unit knowing that Whispers were stellar products in the past but they are far from whispering these days it's more like grinding. I can hear it 2 rooms away from the tank and I have bad hearing as well... not good. Disappointed customer here...I am requesting a refund and I'll keep my old one since the whisper is not even doing half the job my Penguin was doing. SMH
