"Thanks, AquaTech."

I'm currently in the process of receiving another replacement on that model. I used to work as a marine biologist for a major state aquarium. That water got so dirty we had to keep changing it every 2 or 3 days. Months later, this filter is still working great on my 29 gal set up. Never ever ever use it past a year. One thing I think is worth mentioning is the need to prime the filter. That water got so dirty we had to keep changing it every 2 or 3 days.

"This thing is super loud!"

It's easy to clean and we all know about easy. I used to work as a marine biologist for a major state aquarium. SO I decided to order this for my 29 gallon tank. The Aqua Clear is on the left and the Aqueon is on the right. Early on it seems to be working as advertised. You do have to unplug it for those two jobs. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges.

"Great product."

I had to cut the hood to make it work. Typically just below the flat part of the outlets. SO I decided to order this for my 29 gallon tank. This one is working perfectly good FOR RIGHT NOW. I also like the fact that it is relatively low profile and discreet looking. First they are simple and designed to pump and filter aquarium water. My baby turtle even loves it so much he won't let go.

"I like the design."

Now I'm having the same issue with the Aqua Clear 50. Also the maker should review the pump design. I wasn't able to fill my tank fully because there was little to no surface agitation. I ordered 4 of these, for different tanks of course. I own 3 of these and besides my canister they are my favorite filters. I have always used Marineland filters and been happy with them and their quality. You can't really tell though, and the filter is working great.

"Really like the filter."

I stopped the pump and I pulled it apart. I was using a Tetra in-tank filter previously. The instructions are a bit to much for me. The current is strong but you can adjust it with the midsection lever. Clean the foam insert apparently it pulled a lot of dirt and needs cleaned. Overall I would recommend this item. I wasn't able to fill my tank fully because there was little to no surface agitation.

"I love this filter."

Lightly clean the silver roller pins on the ends. A canister or in tank filter is ten times more work and messy. The bacteria eats the nitrates in the water to help keep it clean. Works like a dream and can't even hear it! I own 3 of these and besides my canister they are my favorite filters. Following morning it was running quietly. , that's what makes this so funny.

"I bought this filter."

This filter comes with a sponge, activated carbon, and bio material in a mesh bag. SO, I sat down and read EVERY little thing in rhe instructions. Once it loses its charge, you'll need to replace it. I've been researching so many things on how to take care of them. Fill up the media slot with water until it's full. I have had no issues with it being to loud. I have always used Marineland filters and been happy with them and their quality.

Clean the foam insert apparently it pulled a lot of dirt and needs cleaned. The current is strong but you can adjust it with the midsection lever. You do have to unplug it for those two jobs. The bacteria eats the nitrates in the water to help keep it clean. I thought that U had put it together wrong so I took it all apart and started over. I used a small pair of pliers and carefully got the pebbles out. What I don't like is how much smaller it is than the Aqueon.
