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.

Super Sucker So Sleek

So far so good with this penn plax. Everyone says that the canister filters will leak, but I think if you maintain them well, they will do just fine. I am loving mine so far, and it had helped to clear up a bacterial bloom and a tank crash within a week. I will continue to use this on my 75 gallon tank that is heavily planted and medium stocked with fish. I think it is small enough to hide in the corner. I am going to put it in a tub just to make sure that it doesnt leak on the floor, but its really not leaking and the seals are good. I'm sure you can buy seals 10 years down the line if they dry rot.

Works well

Great canister filter. Pretty easy set up as far as putting it together. Did have some Trouble getting the pump started. Overall great pump pretty quiet wish the output house could extend more into the tank but I'm very happy with the purchase.

Difficult Setup

Took quite a while to get this filter to prime and run correctly. Once we were able to get it to run it has done a great job keeping the water clear and clean in for our two turtles.

Very good and economical

Very easy to set up. Quite operation. Good water flow and ample aeration. Adjustable Intake and Outflow Lengths.

temporary use only

I bought this in November 2021. It burned up in July 2023. No filter is worth $100+ every 1-1/2 years.

Best filter for your money!

I have these on my turtle and fish tanks. They can take lots of different media and are very quiet when maintenanced correctly. Only negative is researching proper gph requirements, because if you go to small they will need cleaned alot and the motor will get loud.

Not as good as I thought

Hooked it up, works fine, but the filter that came with my aquarium kit works better than this filter. Very disappointed. Went back to using the hang on filter that came with aquarium kit. This canister filter does not pull as much water as it claims. The Top Fin hang on filter has twice the pull as this canister filter. Waste of money. Still looking for a place that might have the old Vortex diatom filter. Those were great for once every 3 month cleaning.

I love it!

Love how you can customize the filter media. Had it for 5 years now and it’s starting to make a rattling noise, it’s showing it’s wear but it still works

definitely worth buying

Honestly I’d say it’s worth buying but only when they do the half off sale tbh but I wish it came with better instructions so I would recommend to watch a ton of different tutorials before you set it up and i didn’t know that you had to put the outtake fully submerged into the water, would’ve been helpful if it came in the instructions honestly or maybe it’s just mine that was being weird but it doesn’t make a lot of noise just a humming noise I guess. I personally prefer it over a waterfall noise. Also it can get super messy setting it up so make sure to have a lot of rags with you and use garden scissors to cut the hoses for a clean cut. Also buy bio media before setting it up because it doesn’t come with

Takes a little persistence...

This filter does an amazing job. But getting it to actually prime was a major effort. Don't give up! My filter is for a red eared slider and they are notoriously dirty. Because the water level is not to the top, the sound of the outflow water hitting the tank water is extremely loud. I'm still working on that. But very happy that this works so well.
