Review on Koller Products 1-Gallon Fish Bowl 🐠 with LED Lights (Available in Various Colors) by Michael Tegan

Revainrating 5 out of 5

It works well if you add the right filtering.

I have been keeping various species of fish for about 50 years and have several aquariums ranging from 55 gallon to this large little globe which I love. Recently, while searching the web for some smaller nanotanks, I saw some online comments about bowls like this one. I was amazed to see that many people mistake them for death traps, but the truth is that any tank, big or small, can become a death trap if you're not careful. Lee Round Bottom Filter. Instead, I could (and probably should have) used a very small sponge filter like the Small World filter, since it's easier to maintain. The bacteria on which aquarium filtration depends were automatically introduced into the sphere. The underbody filter is powered by a $5.00 10-gallon Whisper air pump that is easily lowered with an included valve. The lightweight hood lid of this bowl has a slot for air ducts or heating cables and is therefore designed for this accessory - a big plus! The lid is approximately 5-3/4 inches in diameter so it will fit other larger globes as well. I powered the light with a mini USB cable left over from an old cellphone. I always use a combination of living materials and plastic. plants in my aquarium. Live plants are a very important aspect of aquarium filtration, especially in such small tanks. They help absorb nitrates left behind by bacteria. This aquarium contains Marimo Moss, Hornwort and Baby Tears. All three look great with the lights on. I also found a lovely decoration made from fallen logs here at Revain that curves slightly and blends perfectly with the curved side of the bowl creating a lovely cave. VERY SMALL GOLDFISH. Yes goldfish! This is one of a series of feeders I hatched recently. Back then it was not even a centimeter long and ideal for the globe. She lived happily in this tank for several weeks with no visible stress and then I put him in my goldfish pond where he is still alive - and growing. I realize this aquarium cycling method is now considered old fashioned, but it has always worked for me. Finally, after all this, I stick my fancy fluffy crescent tail in the bowl. There it is active and thriving. It has plenty of swimming space, hiding spots, and structures to explore. The bowl is on my computer desk right next to my elbow, so I talk to it a lot. This allows me to monitor him and the water quality closely. So far I haven't had any problems with this aquarium or with its lighting. The plastic (I hesitate to call it "acrylic") is thin but very clean, with some minor imperfections that don't bother me but may bother people used to the polished perfection of large acrylic tanks. The colorful lights are beautiful and even suitable for growing plants in low light. The lid has a recess for the heating cable and the air duct. All in all, this is a wonderful nano aquarium. This 1 gallon bowl is perfect for chicken and some small snails like the two ram horns I carry with me. Many different types of nanofish fry, such as Guppies, such as guppy fry, would also make a great home in this bowl, as would a couple of cherry shrimp. A tiny goldfish can be kept here for a while like me, but not permanently. In all aquariums it is important to carry out a partial water change once a week. Bottom line: add a filter and don't oversaturate, and this little nano shell will work just fine and look really pretty.
