CYS EXCEL Large Glass Bubble Bowl (H-13.5" W-15.25", Approx. 9 Gal.) Round Bowl Terrarium Globe Flower Vase Centerpiece for Weddings Events Arrangements

Beautiful bowl and very well packed.

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.

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.

Very beautiful vase! The size was just perfect, but it has couple bubbles and a small chip :(( Hopefully it’ll last long.

This lovely blown glass bowl is made of relatively thick glass and has great clarity! It was very well-packaged and shipped out very quickly. I am using it as a terrarium for some clubmoss in my kitchen. It makes a wonderful focal point and looks fantastic!!

I needed these for arrangements. They cost way too much money, but I had to have them won’t be buying again too expensive.

The media could not be loaded. The glasses is thicker than my other one. This is good quality.

Either an aquarium or vase, this is a gorgeous well made bowl
