inTankChamber Two Media Basket for Fluval Flex 15

I purchased both the Chamber 1 and Chamber 2 baskets for the Fluval Flex 15gallon. The chamber 1 basket had to be modified in order to fit into chamber 1, and even then just barely. I had to file down the edges that were left uneven where the side and front/back pieces join. Still a VERY tight fit that bows out the Flex's black false wall. Water flows freely between the basket and the false wall at the topright side, completely bypassing the media basket. I had to glue in an acrylic piece to force the flow into the basket. The design of the Flex has a plastic piece sticking off the false wall, near the bottom, and this basket has a notch cut into it that slides over this protrusion. This makes adding almost anything into the basket damned near impossible, as it simply gets in the way of alowing the basket to slide into place. I had to cut that piece out of the tank. The little black "Water Direction piece" is completely useless. First it is so thin and brittle that it was broken in the box and had to be glued back together. Secondly, the notches in the "arms" are cut way too wide and it sits so loosly in the vent that it simply floats out and bounces around in the basket top. If it were designed in a way that that would have stayed where it was intended to be it would still make the stock Flex vent cover impossible to reinstall.The Chamber 2 basket is far less flawed, but still could use some revision. There are no sides on this "basket". This allows the Flex's flow path to still enter chamber 2 a little too low, bypassing flow to the top shelf of the chamber 2 basket. The lack of any sides to this basket (and how loose the 2nd shelf is in the basket) also makes the removable 2nd shelf want to fall out when either installing or removing it from the tank. Whatever you put on that shelf will try to fall out with the shelf.For the price of these baskets I was expecting a product that was not only designed far better, but one that had significantly better build quality. I have acrylic and tools on-hand, and will be modding these to work better in the Flex. This was my first purchase from this company, and it will be my last. These baskets should cost $15 to $20 each for the design and build quality received and are in no way worth anything even close to the $113 they are now.

Purchase this two weeks after buying chamber 1 filter box, Chamber cleared up 90% of the water so I opted for the final stage. I used a aquarium bag with 6 different kinds of media, removed the center tray and hung it from the top shelf. What a difference. The water is as clear as glass and the fish colors are starting to pop and stand out way more than before. Fish seem happier and Im 110% sold on intank products

Absolutely amazing product worth every Penny, I always like to “ Pimp” my filtration to maximize all the space. Excellent craftsmanship and easy install

Although I wasn’t happy that the fluval tank didn’t come with these stock. I was super pleased to find this existed. They work great and I was able to put both in my 15gallon.

After struggling for weeks to keep the water in my Flex nice and clear, I bought both of the intake chambers to help with filtration. After I put them in, the next morning the water was crystal clear! I could not recommend this enough for the Fluval Flex!
