Query: Ultimate Acrylic Bowl

I bought this for my niece and nephew (3 and 6 years) and they loved it! However, I warn future owner(s) not to use the filter pad provided as it is of an inferior quality and will cause bubbles/foam to form thickly on the interior from the top to mid-way down the bowl and limit visbility. I found that when I changed the filter to a HBH Pure-Clear Ammonia (perfect for my fancy goldfish, etc) cut-to-fit pads the water became crystal cleaar and clearer in appearance. Also, if you can, purchase the natural Driftwood replica with life-like aquarium plants directly from www.fantasybowls.com as its the perfect center piece for your aquarium as its built just for the fantasy fish bowl specs(H: 16" W: 10"). Enjoy!
