Penn-Plax Cascade 300 Power Filter – Hang-On Filter with Quad Filtration – Great for Freshwater and Saltwater Setups

Finally able to keep a clean tank!

Bought for my mother's 70 gallon tank. After a day the water looked clean and clear.

I first was looking at the Tidal 110 but decided in this one because it was more in my budget range. I already have several canister filters on my 150 gallon tank but needed something that I could put carbon in to get that extra little bit I needed for my tank to be clear. I think the one thing that stands out about this filter is that there's no way for my eels to swim up into the filter to escape the tank. Most other HOB filters don't do that. The water output is hard to see a difference whole turning the adjustment tho. It's hard to turn amd I don't see any difference in the flow. Other than that one useless feature, I'm happy with my purchase

After reading the instructions, installing everything as instructed, I filled it with water and put the plug in and nothing happened. I emptied the water and took the filter off the tank. I was very disappointed it didn't work right out of the box. It appeared the impeller and shaft wasn't seated properly and there's a lot of play in it even when it is seated properly. So I fiddled with the impeller and shaft, got it to seat properly, tested it in the sink, and then put it back on the tank, filled it with water, and it worked. So, hopefully people will read this review prior to installing the pump and make sure the impeller and shaft are properly seated and working prior to filling it with water and putting it on the tank. Otherwise they will be unhappy like I was having to empty the water and fiddling around with it to get it to work after it was already installed. It seems to work well and has good flow and is very quiet.Update: Filter has been performing well and I cleaned it for the first time. It is much easier to clean than my Aquaclear 110's. It isn't quite as powerful, but much easier to handle and keeps my 38 gallon tank very clear. I don't think I would use it on my big tank though because it doesn't have quite the power and flow that the 110's have. Good alternative if you want to save yourself time and trouble cleaning the Aquaclears.

Arrived completely cracked. I was very disappointed. It was in bubble wrap and if it still cracked that easy, I’m thinking I probably won’t get another one considering the other reviews! Returning it tomorrow! So disappointed.

The media could not be loaded. I bought three one for my 20 gallon and two for my 55 gallon, they're very quiet they've got good water flow and for the price you can't beat it

Best for your dollar. Really good filter. Simple. Easy to clean. Inserts are good enough. It has a high flow rate. I have 6. And one that the housing broke and it was leaking water. But 6 out of 7 are powerhouses.

not deep enough to reach the bottom of my tank even with the extension tube. and it's KINDA NOISY!!!!
