is this too strong for a 55 gallon

Answer by ChewyJan 08, 2020
The manufacturers of this product do not recommend using either of these filters in a 55 gallon tank. Instead, it is recommended to use a 100 gallon filter like the Tetra Whisper UL Air Pump for Aquariums for heavy-duty filtration in tanks less than 75 gallons.

Can I use this pump for a tank that is 100gal. with a lot of fish

Answer by ChewyJan 13, 2018
This pump can be used for tanks as deep as 8 feet, up to 150 or 300 gallons.

how long is the power cord and does it have a ground

Answer by ChewyOct 22, 2019
The power cord for this air pump is 6 feet and it does not have a grounded plug. Aquarium equipment should be plugged into power strips with surge protection, specifically rated for aquariums or a drip loop should be created with the power cord. Instructions on how to create the latter are included with the air pump.

does this air pump have a flow regulater to adjust the amount of air coming out of the stone?

Answer by ChewyFeb 06, 2022
The valves can be adjusted so you get the amount of air you need for each port.

I use this air pump for BIG aquariums. It's the only one I know that I can depend on to deliver lots of air deep into big tanks. It's also surprisingly quiet and lasts a long time. Well worth the higher price. I also like it because it has a single output...a double output (like the Tetra 300) wouldn't have worked for me.

Very pleased that this pump runs the entire bubble wall I have been trying to use in my 55 gallon tank.

Good silent air pump

This is a great air pump for running at least 5 air driven filters per pump and its completely quiet. I have 3 in my living room that can't be heard
