Review on Enhance Your Mini and Nano Tank with MagTool Aquarium Mini Set and Skimmer Lily Pipe by Angelina Collins

I use mine on a "high tech" UNS 5N (4.6 gallon) (pressurized CO2) tank. I also use the built in diffuser. Some of my comments don't apply to those using large tanks or not using CO2. The quality and design of both are very good. There are no visible defects, bubbles, waves, etc. on the glass. The cleaning kit is a nice touch. The suction cups work very well and are almost invisible from the inside of the tank. Drainage is very good. The size is great for my UNS 5N which is only 4.6 gallons. Nano size is ideal for small aquariums. It has enough room at the bend so that the glass tube doesn't touch the walls of the tank. However, it is also very small and does not protrude too much into the tank. A small minus is that the edge of the lily has a small pearl on the edge. This allows the CO2 bubbles from my built-in diffuser to collect there. In the end, a large CO2 bubble is created. I assume it doesn't negatively affect the tank, but I'd rather it wasn't there. At least that draws attention to the water lily. I tested the ADA lily tube on my LFS and they don't have an inner bead at the top to allow those bubbles to come out. This is a minor issue as few people will ever use a built in diffuser or CO2. I would not use a skimmer inlet in my smallest aquarium. That's too much for my 5g. It takes up too much space and affects how you get out of a tank of this size. It looks/fits better when used with a larger tank, but some evaporation will occur without the cap. This lowers the water level and sucks air into the skimmer. This has nothing to do with the skimmer, but is worth mentioning for those who use tanks without a lid. I went back to using the standard inlet that came with the filter. For smaller tanks I would like another nanokit with a standard inlet tube. If you don't need a skimmer just look for a nano sized exhaust pipe (not sure if they sell it). All in all they are very good for the price.
