Fish Tank Filter Small Pond Filter for 100-200 Gal. Tank Crystal 420GPH Biochemical Filtration Powerful Submersible Water Pump Large Aquarium Accessories Air Supply

Very happy with the tank filter. The flow coming out was impressive. Very high flow. I would buy it again when I need more. Recommended.

I took in some turtles and the filter they came with was horrible. This one took the murky water(from sand that I washed a million times) and it is crystal clear!!! The turtles love the air stream they walk at the bottom, swim up to the opening and let it take them on a ride. It’s so worth the price. Easy to clean and came with clear instructions such as sit at the top of the take for fish and bottom for turtles. It doesn’t take up much room for it to be so powerful. IF I need to replace it I would definitely just rebuy this one but I highly doubt that will be any time soon.

Needs a flow control on the output otherwise works pretty good.

This is the best filter I've had so far. Usually I would have 2 of these type of filters in my 75 gallon tank, but 1 does just the job right. It's a bit noisy but pushes out enough flow to pick up the mess a turtle can make.

Came damaged. My old filter broke & not too sure how this one is working yet. I have 4 turtles in a huge 75-100 gallon tank. Hopefully this clears up the water.

I bought this for my turtle because I needed something that could clean 2-3x my tank size. I have a 55 gallon tank so this is perfect. I have a pet turtle and let me tell you, this thing added CURRENT to the tank. It's definitely very powerful! Be prepared. But he loves it, it gives him some entertainment as he races against the current for the turtle triathlon, and he likes the bubbles feature too.

It’s ok for the money but it’s not worth it in the end . I bought two of these 100-200 gal filter however they are cheaply made one type of filter media inside and it’s not doing it’s job!!!! a filter is suppose to filter out the impurities. Everything big an small gets stuck on the side of the filter and clogs it up. It’s not filtering the ammonia or nitrates or anything for that matter.However it has a great suction and stream ! so strong it blows my fish everywhere no matter how low or off I turn the knob. These filters should only be used for a wave maker an a water mover maybe but other than that it’s not a good purchase

We have a large fish tank we keep out on our back porch and we have had to replace the filter several times, we were using the large expensive ones. When my last one broke I decided to just get something cheap since we have to keep replacing it anyway, algae tends to take over the tank because of all the sun it gets. I really just wanted something to keep the water moving since we only have one fish in there... I stuck this in there and came back out a few hours later and the water was so clear! Most of the algae had been pushed to one area which allowed me to scoop it out too. Definitely impressed and very happy with the purchase. The amount of water this thing moves is crazy!

This is a great addition to my aquarium, while it is made for up to 200 gallons it works great in my 100 gallon tank. Keeps my water clear and the fish love it!

Tsunami. Should have got size smaller for my 75. Very very powerful. Decent filtration clear water

Works amazing in my 110 gallon tank. The water flow is powerful i also like the buble feature.

Was the same one I returned about a month ago, that was broken and missing parts. Will be returning it, again. Disappointing.

This thing really pumps out that water flow. It's too loud to be in a room you sleep in, but it's been amazing. Have set up in a 136 gallon
