3G-DM048PNP Medium Artificial Coral Inserts Decor, Fake Coral Reef Decorations for Colorful Freshwater Fish Aquariums, Marine and Saltwater Fish Tanks

Very nice product!! Simple to use and looks excellent in the tank! Make sure to soak it for several hours and change the water frequently. This will make it easier on your skimmers.

First day water was a little cloudy but after a 15% water change everything appears to be ok. Arrived with several small pieces broken off but Instant reef shipped a tube of "aquarium safe" silicon. Packaging could be a little more friendly. Still finding little pieces of foam swimming around even after a very thorough initial cleaning. Could be packaged a little better.

I purchased this product and it poisoned my tank. I’m a veterinarian trained in fish medicine and I have over 30 years of experience with marine tanks. I followed the instructions on pre-soaking the “corals” and added only one at a time. I’ve tried to contact the company over email with zero response. I warn everyone to stay away. Toxic products and horrible customer service.

It looked as advertised but it was, and is, a big headache for me. It came well packaged in foam squares BUT lots and lots of small foam pieces were stuck in the coral. I used my air compressor to try to blow them out. Would have been nice if they just wrapped it in plastic first. I rinsed it well and then put it in my tank and thats when the next headache occurred. The water turned milky and nothing I do cleans it up. I called instareef and they recommended a 50% water change and said "sorry" but if I had read more carefully I would have known this was going to occur. WHAT? That suggests you would never want to buy one of these unless you are just setting up a NEW tank which I was not. So, its nice looking but I definitely wouldnt purchase for an existing tank. Its been a headache that quite frankly I didnt need.

Super cool looking under the lights and more impressive than the pictures show. I bought more.
