Questions & Answers

I have a 75 gallon salt tank which pump is best. Am thinking of buying the 900 is that ok?
Answer by ChewyJan 18, 2019
When choosing a pump, it depends on the fish you keep and whether you are using it for circulation or surface agitation. We generally recommend that on average, you turn over your aquarium volume four times per hour. This means that if you have a 75 gallon tank, you need a pump and filter with flow rates of around 300 gph.

I'm wondering rather to go with a strong air pump or the 1200 for my under gravel filter.... your thoughts?
Answer by ChewyFeb 04, 2022
This pump is perfect for operating under-gravel filters and offers your tank excellent circulation.

is it compatible with a Penn pass 50 gallon under gravel filter?
Answer by ChewyDec 07, 2018
This circulation pump could be used along with the Penn-Plax Premium Underground Aquarium Filter.

On the Marineland penguin submersible power head size 900 is good for what size tank
Answer by ChewyNov 27, 2018
It's generally recommended to turn over your aquarium volume four times. For the circulation pump mode, the 900 would be for a tank of up to about 225 gallons.

Great Buy! Comes with Circulation Parts

These pumps work great! Much quieter than others I have tried.

This is a quiet but strong pump

This pump comes in four sizes this was the biggest one I am thinking it’s too strong for what I need but it will work just fine.

Great Water Circulation but Little Oxygen

As mentioned in title. Powerfully circulates water and moves debris around which settles and collects over time, allowing for easy maintenance. I used this for over a year and was satisfied for what it could provide. However, it requires routine cleaning as food and debris are often caught in the vents, creating sludge and other bio-hazards.

Powerful inexpensive pump

I bought this pump to provide a little extra circulation for the large fish tank where I work. It certainly does the job and was inexpensive to boot. Great purchase.

Excellent you need it!

We purchased this to get the water flowing better and circulating better. Our fish swim a lot more now and the tank hasn’t had any algae since putting it in the tank a month ago.

It works for me but.

This moves a lot of water in my 38 gallon tank. When ever i turn it on i see a lot of debris and stuff getting suspended and floating all around. The reason why i give 4 stars is because when you turn it into a different function sometimes as you are putting one piece another one is getting disconnected and falls apart, and then you fix the piece that got disconnected and the one you had previously put together starts falling apart. and so an and on until you get the thing to work after several tries. Sometimes i get so frustrated putting it all together without the thing falling apart.

purchased some items from chewy for the first time because of this epidemic and I order this pump and once I installed it as I had pumps before in the past. and tried this one because It was recommended to me. I install it and than it doesn't it turn on. so I decided to leave and than I tried again today and it turns on slowly. and than turns back on..horrible product. not what I expected from CHEWY and MARINELAND! NEVER AGAIN

Mainland jet pump

This product is fantastic. I the fish love it and keeps them motivated. It's like their swimming upstream.

It’s ok for what it is

As the title states, it’s cheap, loud when configured as a circulation pump but seems to move water well, at least for now. It’s pretty cheaply made but this was expected.
