"Like brand new."

My tank is nice and clear and my fish are much happier. I had to cut the hood to make it work. I will never buy any other HOB no matter what deal they might be offering. So, easy is good, both for us and our fish. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. It started out silent for about 30 mins and then it got super loud. My baby turtle even loves it so much he won't let go.

SUN 07102 Final Thoughts

"A THUMBS UP."

A canister or in tank filter is ten times more work and messy. LOW and BEHOLD, LMAO, I missed where you had to put water in the back of the filter. I will never buy any other HOB no matter what deal they might be offering. However, lately I've purchased the Aqua Clear 70 and 50. I ordered 4 of these, for different tanks of course. This one is working perfectly good FOR RIGHT NOW. However, lately I've purchased the Aqua Clear 70 and 50.

"SAME THING!"

Firstly, I'd recommend taking the motor apart and putting it back together. I use Marinelands refillable cartridge for extra carbon on the extra slots. I sent a request for replacement and one came the next day. I want to answer some of the complaints I've read. Never ever ever use it past a year. , that's what makes this so funny. The instructions are a bit to much for me.

"Yeah, no no no!"

They can be very noisy at the impeller, which sometimes quiets in time, but may not. I will never buy any other HOB no matter what deal they might be offering. The filter arrived within 2 days and was the exact same as Petsmart's. This filter comes with a sponge, activated carbon, and bio material in a mesh bag. The first night I had the pump going it started making a screeching sound. This lives up to the praise that people give it. Early on it seems to be working as advertised.

"- Plug it into power."

I stopped the pump and I pulled it apart. I own 3 of these and besides my canister they are my favorite filters. Now I'm having the same issue with the Aqua Clear 50. It doesn't rise up hugely above the tank like a lot of HOB filters. You do have to unplug it for those two jobs. Your fish and you will be much happier and stun everyone else. It doesn't rise up hugely above the tank like a lot of HOB filters.

"That also didn't work."

I've been researching so many things on how to take care of them. I can take apart a car engine and put it back together. The ability to regulate the flow solves the loud waterfall problem. This is a good choice if you're tired of cleaning your turtle tank all the time. They were great to deal with and the new filter is working great! Doing research I learned that if I add more filter media, the noise will subside. I've been researching so many things on how to take care of them.

This lives up to the praise that people give it. The first night I had the pump going it started making a screeching sound. Marineland bio pumps have been around forever.

"Seriously."

Worst case is that the motor could burn out. Firstly, I'd recommend taking the motor apart and putting it back together. My old pump was not working very well so I had to make a major clean up. Doing research I learned that if I add more filter media, the noise will subside. A canister or in tank filter is ten times more work and messy. I was new to the hobby and didn't realize that Tetras were inferior filters. It's only rated at 25 gph less, but holds considerably less media.

Fill it up with water before you plug it in. The Aqua Clear is on the left and the Aqueon is on the right. You do have to unplug it for those two jobs. The bacteria eats the nitrates in the water to help keep it clean. However, lately I've purchased the Aqua Clear 70 and 50. SO I decided to order this for my 29 gallon tank. My baby turtle even loves it so much he won't let go.

The instructions are a bit to much for me. BUT after some YouTube research I was able to fix the noise issue. Clean the foam insert apparently it pulled a lot of dirt and needs cleaned. My tank is nice and clear and my fish are much happier. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. Works like a dream and can't even hear it!

One thing I think is worth mentioning is the need to prime the filter. I eyedball everything and put it together with a look back at instructions. I used to have a 37 gallon eclipse aquarium. With the 350's inexpensive price point, you can’t go wrong with this powerful filter. I still have my original wheels on the year old 350 with no issues whatsoever. It's easy to clean and we all know about easy. There must be a huge batch of these units at Amazon right now that are bad.
