Universal Rocks 48-Inch by 20-Inch Rocky Flexible Aquarium Background

Arrived in record time! Ordered it on a Tuesday, received it on Thursday. Came well packaged and as shown in the advertisement. I had been debating buying one of these for a looong time. I had looked at every company that makes them, DIY versions and pretty much every possible route to go for my 75gal. Universal Rocks stood out for me. They are well made, durable and easy to install. The clips provided may seem low-tech, but the idea is to have this panel rest against the back wall, under the lip of the aquarium. I recommend going to Universal Rock's site as they have a whole section on using the clips, installing and placement. I did this while doing a normal H2O change only I completely emptied the tank of decorations and plants. Gravel vac'd thoroughly and installed with my stock of 20 cichlids still in the tank. Scrubbed it completely first and put it in. Sank right out of the box and bent around the center brace with total ease. At first it was approximately 1/4" too tall for the tank. I removed it and using kitchen sheers (very tough and tedious and I would recommend tin snips for the job) I trimmed the bottom of the background. Fits like a glove! Clips went in place no problem and looks awesome! I would not hesitate to purchase anything with Universal Rock's name on it. I contacted them directly with several questions and received excellent, quick responses every time. If you have a particular question that is holding you back from purchasing, ask them and they will resolve any doubts. This really makes me proud of my tank. Looks awesome, is durable and will make any tank a showpiece. Will definitely be purchasing another for my other 55gal tank as well. 100% SATISFIED!!!!

You cant go wrong with this one. I was thinking a lot to spend the $85 for this, but the compliments I received so far beats the price I had to pay for this. The background looks realistic and since its is made of fiber glass like material, it will last for long, very long. Agree with some of the other people's experience on getting this into the aquarium, it takes a bit of effort and will advice you to take everything out other than the gravel and water if at all you have already setup yours.The size is actually 0.25" shorter on both sides (length and height) which made it very convenient for putting it in and mine fit like a glove. I will give this one 5 stars all the way.

This is stunning and fantastic price. The photo is a 54 gal corner tank. The flexible background slipped in and gave me a sump in the back. I cut a small access hole in the bottom. (To let the fish and snails through) Drill a few holes to let the water flow freely and I'm thrilled.Worth every cent and makes a whole new tank.Edit Update: After two years, the background looks as good as the day I got it. (Even better, there is some algae growth on it now and it looks like a natural rock wall. I'm not sure what the other reviewers are talking about with PH problems. From day one I never got the slightest spike. I was concerned that the coating on the rubber mat would flake off after time, but I have not seen any issues with that. I would recommend that you not silicone in place as I did if possible. I am needed to pull it off for proper glass cleaning and it is going to be a much bigger process than it should have been.I can't say enough about the product and am buying another sheet for a couple other smaller tanks that I have around the house. (Because who says you can't have 8 tanks in the house)

First of all, the "clips" that come with the background are just rings of plastic. They were very difficult to force over the edge of my tank and once there, the rubber background easily slid out from under them. In case it isn't clear from the other descriptions, yes, this product is made of rubber, and another interesting thing about it is that it floats. It is in fact *so* flexible that it bows in the middle from trying to float. The packaging says that it can be siliconed in, what they mean is, it *must* be siliconed in. It says that you can keep it in place using clips and gravel. I have three inches of gravel at the bottom of the tank, but after trying to wrestle this thing against the glass for the better part of half an hour, I'd say that I'd need at least 7-8 inches of gravel and several large, heavy rocks to keep it forced back flush with the glass.So, here's some installation instructions based on real-life use:#1- get some aquarium grade silicone. I don't know how much you're going to need, but guessing by how rippled/pitted the backing is, my guess would be: a lot. I'm also going to need silicone to plug up some holes- mine had about 6 pea-sized holes in it, and I don't want my guppies swimming through them and getting trapped behind the background. Speaking of which-#2- don't buy fish until this thing is installed. If you're thinking of installing it in a tank full of water, I hope you have waterproof flooring because it's gonna be messy. Every time I try to push the background back up against the back of the tank, all the water behind rubber sheet takes the path of least resistance- up, out, and onto the floor. Then, the background falls off the edge again as soon as I let go of it. Right now, it's sitting in a slouched mess in my tank as I try to find 55 gallons worth of clean buckets to-#3- drain the tank. You're going to need to take the tank down, empty the decorations and gravel, thoroughly dry it, and lay it on it's back. I haven't gotten this far yet, but I anticipate trouble. My lid had a bar down the middle, so I will need to bend the background to get it laying in the tank, meaning the silicone will need to go between the background and the glass after the background is already in the tank. Then weight the background down so it doesn't move, wait 48 hours for the silicone to cure, rinse the whole thing out (somehow..... the tank is wider than my shower and it's 20 degrees outside.) Not sure where I'm going to put the fish in the meantime, but I'm sure I'll think of something. Gotta say, tearing down, storing, and rebuilding an entire 55 gallon tank is not what I had in mind when I read that it was "easy to install."In short, if you're sitting in your house with a dry, empty tank, wondering if this would be a good accessory, go for it. It looks pretty good for what it is. If you're looking for a nice background for a tank that already has water and/or fish, I'd give this one a pass.Edit: altered my review up from two to four stars because, after I drained the tank, filled a spare 10 gallon for the fish, cut the background to shape, siliconed it in place, waited two days for the silicone to cure, and refilled the tank, it looks *spectacular.* It looks like real stone and I'm really happy with it. It's a very hard install, though.

This background looks amazing in the tank. fit perfectly in my 75 gallon aquarium. Amazon was almost 1/2 the price as anyone else with free shipping ( I think free shipping because I'm a Prime member ). Highly recommend this to anyone who wants make there tank look more natural .
