Review on 🐠 Hygger Small Betta Fish Tank with LED Lighting: 4 Gallon Desktop Aquarium Starter Kit with Lid, Filter Pump & Cartridges - Ideal for Snail & Tropical Fish by Mary Walters

It can be seen that this aquarium is beautiful. The lights/top are integrated into the whole setup. However, there are many problems: Heating: There is no heating in this configuration. There is a temperature gauge but no heater. Therefore, you need to buy a heater. In addition, this heater differs from the indicators by 2-4 degrees. Filters: I think the filters/cartridges are not good. I tested the water and found high levels of contaminants many times. At the moment I do water changes 2 times a week and I change the cartridge almost less than 2 weeks at a time because it doesn't really filter properly compared to traditional filters. I also bought plants and these "organic" cubes to try and help the chemicals in the water. For now I will create/modify their filter and see if that helps. Cleaning: Tank components are not easy to clean. There are little tubes and bits in the filter that I use a ton of cotton swabs to get in and they come out with obviously algae. (Given that I clean weekly. That seems silly). I have the tank at the moment but I wouldn't buy/recommend it to anyone else based on the sheer service I find.
