Fluval G3 Filter Review

Beautiful Aquarium

I have a huge beautiful aquarium in my dining room that provides a lush view for the sitter. But, there is a problem that the aquarium water creates turbidity in few days and creates a foul smell in my dining room. It also creates a bad impact on our appetite and we can’t enjoy our meals due to its smell So, I decided to clean it by myself but it became a big headache for me. Because cleaning a huge aquarium is a very hectic job if it is done manually, it takes hours to do it. Then, I decided to purchase a filter of good quality because my previous filter was not working properly. Here begins a struggle to search for a good quality automatic filter

The next day I call my friend. She is an expert in aquaculture and does a job at a private organization. She recommended me the FLUVAL G3 FILTER which she was also using at her home. At very first glance I liked that filter due to its following features.

A hard brush that is provided helps to clean the cartridge and again filled by media of your own choice. The neat and cleaned cartridge again reinstalled, locked back into place, low the lever and restart the filter. There is no need to prime the filter again and if the air is entered into the filter it can be released after some time. There is no other filter of any company which provides the killing feature.

One of its best features is the outer shiny layer around the canister flexes. Although priming works efficiently and needs a few pushes for water to flow into the filter. It would be useful if you mention the inlet and outlet pipes with an arrow. This would be helpful to avoid the wrong connection of pipes. The pipes of the filter are opaque and it is very difficult to see whether it needs cleaning or not. In this case, the monitor of the filter will show the issue. The attachments between hoses and tanks are greatly improved but do not work with all kinds of filters.
