## Description

This set is for 20 gallon standard aquarium. 3 pieces of acrylic dividers will be included for each order.

Review: Almost perfect... - Perfect cuts, packaging, clean and no scratches... however.. measurements were off by 3mm for my standard 10 gallon seapora glass tank. I had to use a saw and trim it... but overall good.
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.

## Questions & Answers

**Q: do the dividers come out?**
A: They need to be silicone in or something silicon then so these can ride in and out.

**Q: does it matter what order the baffles r in?**
A: I would assume not, you really want to have your sump flowing in one direction and this helps that. I think common sense plays a big role here.

**Q: I would like to know the measurements of the tank that are not very obvious to me. There are more non-tank divisions**
A: This kit is designed to be used with the standard 10 and 20 Gallon tanks. They should be measured with the Aqueon Tanks. 10 Gallon tanks measures "LxWxH" (20"x10"x12"). Other size options are for the 20 Gallon Tall/High (24"x12"x16") and the 20 Gallon Long (30"x12"x12").

**Q: I just received my kit for the 20 gallon long. Are there any instructions or guidelines?**
A: No.  Just follow the pictures.  Wait!  Can't really see them, huh?  Getting a one-star review for lack of simple instructions.  Nice clean cuts on the acrylic though.  I bought one off of Ebay that had very clear and detailed instructions.  It' on a piece of paper, and they just make copies.

### ⭐ Major let down make your own
*by A***K on 2 May 2021*

Great so you give me 3 crazy expensive plastic panels. I honestly though this was a tank. It shows up and it’s just 3 panels. And they don’t even have parts to hold them in the tank. No instructions no accessories your just on your own. And if I have to diy these into place I might aswell cut them myself for the 5$ of material they are actually worth.
