About this part

An open filter chamber and a lively return can churn the surface and push your decor around. This one-piece lid and baffle closes the top of your AquaClear 50 and calms the returning flow at the same time, so your aquascape stays put and curious fish and shrimp stay out of the filter.

Legacy AquaClear or Fluval AC? Fluval redesigned the AquaClear filters as the Fluval AC line, and the lids of the two versions never fit each other. If you are not sure which one you own, check your filter before you order.

Compatibility
  • Fits: the Legacy AquaClear 50 hang-on-back filter (made before the Fluval AC redesign).
  • Does not fit: the Fluval AC50. See our Fluval AC lids.
Why it helps
  • Lid and baffle in one part.
  • Calms the return flow for a quieter surface.
  • Seats firmly, with no rattle.
Installation
  1. Take off the stock lid.
  2. Set the lid and baffle in its place.

I bought this as well for my aqua clear 50 filter to baffle the flow for my floater plants and betta. Lid is snug but fits and doe not make rattle noises.

Ordered this after my lid went missing and then my cat took off with the bio media, effectively killing my cycle. I needed a new lid anyways, plus the current was just way too strong for my fish and new plants.

After ordering I sent a message to the seller explaining and requesting as fast as possible shipping. I had this in just a matter of days!! At first the lid didnt seem to want to go on. But after moving it around a tiny bit in the back it's a perfect fit and doesnt rattle like original Aquaclear lids. Plus its tight enough that I doubt the cats will knock it off intentionally or accidentally.

The baffle/diffuser works PERFECTLY. The water goes through and instead of being a waterpark slide current shooting straight out and down, it breaks the stream up, causing the water to instead trickle straight down into the tank.

Works great, fits snug, tried a few other water diverters and wish I would have got this one first.

I I want to love this but it straight up doesn’t fit. It doesn’t fit snug and has gaps. The quality is fine and the shipping was great, but it doesn’t fit at all like it should no matter what I do.

This topper does it's job perfectly. Only small complaint is that it's pretty sticky to get on and off. I assume that will loosen in time. Other than that, it's great!

Exactly as described. Been using it for a while now and I’m very happy with it.

I had to order the original aquaclears U intake part to fit it on the new version of aquaclear, but once I put that on, will a little precision fitting, it snapped on like it was just another accessory the company offered. Its a tight fit but its not tight in any bad way. Super cool. Awesome product. If you guys can think of pretty much any kind of 3D printed accessory to my aquaclear 50 filter ill buy it. Take my money. Lol.

I gave it 5 stars for a reason, lol

At first I thought I bought the wrong filter cover, because this doesn't fit the Fluval AC50 I own.

I'm guessing that Fluval updated their filter design, the sliding arm that controls the filters flow is too tall and keeps the lid from sitting flush. Since they have a no returns policy, I just have to eat the $25 I spent on a design that doesn't work.

Great quality, snaps right into place!

Great quality item, very snug fit on the filter box. I was not aware that by adding this it would cause the water to curl under the filter and get on the lip of the tank a little, it does however redirect the flow of water from straight out in front to curl under a bit and hit the glass so just be aware of that. My plants that are back there are taking a bit of a beating.

Second item and will be buying two more. Nice fit and function and looks good. Thanks!

Fits perfectly! I bought a stronger filter recently but the flow was a bit too loud and was not disrupting the surface enough. This cut 90% of the noise and, as a plus, its shape helps direct the water in a way that agitates and oxygenates the water more noticeably. Very worth.

Fits good. Really helps with flow.

Perfect fit on the 50!

Excellent product. Perfect fit for Aqua Clear filter.

Perfect! I needed to baffle the flow for my floating plants and Killifish. This doesn’t require extra ‘fall’ space in my lid, doesn’t need suction cups that fail after a couple years, and Does baffle the flow! Fits tightly enough not to rattle.

Perfect. Exactly what I was looking for.

It works as it should. Will buy again if needed.

It fits perfectly, if not overly snug. The shipping was extremely fast (and I live in AK) I was pleased that it did truly snap right onto the filter without a fight. I have a 50 gallon filter and it does not cause any leaking or back up. I plan to purchase more products from this seller thanks to the quality of this item.

My original order never made it to the door likely to factors outside of either of our control but after talking, a replacement was promptly sent that works great!
