Large Glass Bubble Bowl (H-13.5" W-15.25", Approx. 9 Gal.) | Multiple Size Choices Fish Bowl Vase | Glass Round Bowl Terrarium | Globe Flower Vase Centerpiece

I’ve had this bowl for about a year now and it hasn’t cracked or chipped. Holds 9 gallons of water if you fill to the top with nothing else in it. With all my substrate, plants and decor in it the bowl holds 7 gallons of water. I have an aquarium heater inside that keeps the water at 78 degrees, and a filter…the tank is large enough to house all necessary equipment to keep live fish.

I use this as a fish tank. It’s graceful, clear and large enough for a beautiful aquascape and fish.

I bought this CYS EXCEL 13.5"H x 15.25"W to set up as a Low Tech Heavily Planted Walstad Bowl in which I plan to populate with Neocaridina shrimp. OK...that being said...it's a beautiful bowl...really nice size. I just want to point something out to potential buyers that may be a critical factor in decision making. If the volume in gallons is a critical factor in your purchase (which it would be if you are into aquarium tanks, bowls, etc) then I need to point out what I believe is a discrepancy. Using the Height of 13.5" and the Width of 15.25" I did a simple volumetric calculation to determine approximate gallons. The AD here says '9 Gallons' which my calculations do not support. Using inches and the Volume Formula for a sphere I calculated volume as follows: The Volume Formula is [V=2πr³/3 ](where r=radius) I divided the Width of 15.25" (which would actually be the Diameter) by 2 = a 7.6" radius. Now plug it into the V-formula! V=2π(7.6)³ /3 =2756.8/3 = 918.9 in³ volume now to convert to gallons---> multiply that by 0.004329 gal/per in³ Sooooo...we have Gallons= (918.9 in³)(0.004329 gal per in³) the in³ cancel out and you have 3.97 gallons. So it's just about right on for a 4 gallon bowl. What would it take to get to a 9 Gallon (as advertised) bowl? Doing a little reverse math I came up with a 10 inch radius in our formula to get to 9 gallons volume. That would be a bowl that is a good 20" wide across (given the same height 13.5") So...just sayin'....I do love this bowl for what I intend to use it for. But before I bought it I did the math and realized it's just a 4 gallon. Not a 9 gallon. If I am wrong (it's happened many times before!) I would like to see the seller and/or manufacturer's math on the volume calculation. In other words...HOW they arrived at 9 gallons. I'm not trying to be picky or slam the product it's a great bowl but for those of us into aquatics, bettas, shrimp, snails, & other nano fish...the difference between 4 gallons and 9 gallons is substantial in the planning of a living bowl.

Perfect beautiful bowl hard to find a large bowl but Amazon had it Richie V.

Mizu tested, Mizu approved! I wanted to create a maintenance-free ecosystem bowl for my Samurai Betta Mizu, who is sadly going blind due to being a dragon scale variant. This bowl is perfect for what I needed, the glass is thick and sturdy, I see no bubbles in the glass, and I like the smoothness of the cut top (no sharp edges). Mizu enjoys his food staying in one place, and having ample room to roam.
