Review on Underwater River Air Pump Small by Michelle Ortiz

So I saw this and thought it was going to be cool. I wanted to upgrade my 5.5 to 10 gallons. So that looked like a good chunk to add. So when I got it everything was there. So if you have trouble with the suction cups, gravel them first. There are almost no instructions, but it's easy to understand. So I had problems with blisters, they were so big. So I read the review and someone said they put holes in this rubber air stone like thing. I did this but I still had problems and the review said it worked after a few days. That's what I thought, and I had already installed a tank. I already had an air pump and an air stone. So I used the little 1" air stone I had instead. It looked better straight away and when I woke up it was perfect. 4 stars for that bad "air stone". But that's my solution: USE ONE OTHER AIR STONE IF BUBBLES ARE LARGE.
