Questions & Answers

I have a turtle and his tank just gets too dirty . Will this help with that ?
Answer by ChewyJan 30, 2020
Keep your turtle’s swimming water filtered by using a canister filter or power filter. The more powerful the filter, the better for your turtles, unless they seem to be fighting the current. This filter uses mechanical, chemical and biological filtration for crystal clear water and it would be perfect for your turtle tank.

Do you need under gravel filter or other filters when using the penn-plax? Do i.need power heads or anything else?? Can you use the 100 gallon one on a 55. I am setting up for ciclids
Answer by ChewyNov 02, 2017
A power head does not need to be used and this filter will cater to many needs but you can add an extra filter if you would like. Also, you can use the 100 gallon for a 55 gallon tank.

I like to turn all filters off while feeding will I need to prime them when restarted?
Answer by ChewySep 01, 2018
If the flow control valves are shut off before the power and the canister is not opened, then there should not be a need to prime the unit again.

How long are the input and output tubes?
Answer by ChewyMar 28, 2018
The input and output tubes outer diameter is 7/8 inches while the inner diameter is 5/8 inches. The tubes measure approximately 6 feet long.

Easy and efficient

This was my second purchase of this product. I originally purchased the smaller version and could not pass this up when I saw the price. So far I am very happy with my upgrade.

Great small canister filter

I bought this filter to use as a gravel washing filter for my freshwater tank. It is extremely well made and works like a charm. I've read other reviews that complained about difficulty priming the unit but I usually fill it with tank water before starting and have not had any problem even thou I only use it to gravel wash. However the unit is so well made and reliable, I would have used it as my primary filter if I was at all unhappy with my Seachem hang on back filter. I highly recommend this filter for tanks in the 20-30 gallon size.

It works great so far.

It was easy to put together but it is tall it was almost 12 inches high plus the hoses at least the hoses can move around it almost did not work for me I built the stand many years ago for my 55gal tank and it barely worked. I had other tank filters under it.

Penn plax cascade filter

Having more than one aquarium and aquariums for many years I'm not a fan of this filter. Added media to the top 2 trays, set up correctly but does not keep aquarium clean and clear. My other tanks are perfect with no issues. Always over compensate filter size as well. Been almost a month running getting ready to change filters. Not impressed don't waste the time.

Impeccable filtering system!

Keeps the water crystal clear for months!!! Not recommend for shorter tanks though (e.g. a 30 long tank)

I have four of these canister filters running in my home and I love them! Won’t pay the ridiculous price of competitors these work amazing my oldest one has been running for two years no problems!

Over rated

This is not adequate for 30 gallons. For any tank 30-60 I recommend at least the 700. 60-90 recommend 1000. You can't have too much!

No way never again

I’m having to replace this filter yet again I’ve had two in the past year and a half and now I’ve spent two days trying to pump this one to get it to start sucking the water up again it’s awful

Cascade filter

This filter replaced the same brand and model that I had used for twenty years. I hope that this one will last as long. I wouldn’t use any other type of filter.
