### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works Well But. . .
  

*by S***A on Reviewed in the United States 🇺🇸 on April 12, 2013*

I ordered this for my office fish tank. My only complaint is that there wasn't much information about it. It doesn't come with a pump so you do have to buy that separately. In my office we have a small 5 gallon tank containing a gold fish and a betta. I bought the smallest pump I could find and once I put everything in my tank and turned it on the force of the bubbles created a virtual earthquake. I guess my complaint is the air hole, maybe it could be smaller so the bubbles weren't so intense. The bubbles in the picture are nothing compared to the bubbles that actually come out. After that we decided to prop the door open and just leave it in the tank as decor. Two days after we did that our fish ended up with an injury from bumping into the very sharp edge on the inside of the door. We ended up taking it out completely and don't use it at all anymore. But it does work well and do what it's supposed to I just wish I had known it wouldn't work for my small tank and Black moor (they don't see well).

    hard to install
  

*by P***R on Reviewed in the United States 🇺🇸 on September 18, 2011*

I may install this later. The problem is the tiny hose that gets kinked easily in the gravel. Perhaps this was meant to be installed in fine substrate!!!
