Review: These dividers are great and fits perfectly. - So I decided to take a chance on this since it was pretty cheap for what it was and it turned out great. I don't understand what people are talking about it not fitting the Aqueon 10 gallon tank but it fits mine perfectly. As far as instructions go, no there's no instructions but just look at the pictures. It's really not hard at all, you don't need instructions for this, the pictures show how it's supposed to be. If you're not sure then look at the video I posted with this. I saw there were some people that were surprised or disappointed that it didn't come with the tank? Look guys I'm sorry you didn't read when it clearly says it's the chamber dividers and that the tank nor silicone was included. I'm actually surprised it came with the piece of foam you use to put in between two of the dividers. People were saying that the pieces were thin and flimsy but if you look at the video review they are quite thick and sturdy. There was also people saying it was too pricey but have you seen the prices of already pre-built sumps? Compared to that this was pretty good I got the tank for $15 that was 50% off from Petco and these for 29 bucks so for what 45 bucks I got a sump, you can't beat that anywhere. So at the end of the day I think it's a pretty good deal for what it is especially compared to how expensive equipment can be for a salt water reef tank. I'm actually thinking to buy the 29 gallon kit just for the future whenever I eventually upgrade, just already have it on hand.
Review: Amazing quality - Super high quality and fit like a glove in a 40 breeder. You could put it together in your sleep with one hand tied

### ⭐⭐⭐⭐ Great product, just really short!
*by P***S on May 30, 2026*

If you are looking for a baffle kit that is an exact fit for a 20 gallon standard (NOT 20 gallon long), and you only need 7(ish) inches of water depth, these baffles are perfect! The green/yellow neon color is actually really cool and the vents are very precisely cut. Overall this is a well made product. UNFORTUNATELY for me, I didn’t realize they only provide 7 inches of depth. Part of the reason for using a 20 standard instead of a 20 long for my sump, was to get the extra depth. So I’m back to buying sheets of acrylic and cutting my own baffles. Hopefully this helps someone else!
