I started up my 28g Nano-Cube back in November of 2009. Overall I’m very happy with my decision to purchase the Nano-Cube. When I was making the decision between tanks, I had a couple of concerns. One was heat and the other was cost. While I use to have several fish only tanks and owned an aquarium maintenance business, I had left the hobby more than 15 years ago. This would be my first ever reef tank I wanted to keep the cost at a minimum while I determined if my schedule and life would support a reef tank long term. As I mentioned my considerations were heat and cost, I did not give filtration much of a thought.
After getting the tank setup, one of my first observations was that the stock media basket did not handle the entire water column as it hit the media basket. While my first instinct told me this was a flaw, I figured that it must be good enough. As the tank ran, I just could not get the floating particles in the water to go away. Filter floss, sponges, etc, were added to the media basket, rinsed and replaced a couple times a week. After 2 months with filter floss, still not much improvement to the floating particles. While I kept coming back to the undersized media basket I could not find a product on line that would replace the stock media basket.
That is when I made the decision to make this a DIY project. I did as much reading as possible. Stevie T’s DIY thread was very helpful. It was here that I discovered the evolution in glues that he used for his media baskets. I finally found a plastic supply company close to my home that sold the acrylic and plastic weld needed to get started.

After several proto types, I quickly learned what a pain in the butt this project was really going to be. Because of the lip on the back of the tank as well as the overhang on the overflow the amount of room to work with in the back chamber is very limited. I made 3 different baskets before I found one that would handle the volume of water entering the middle chamber. That was the birth of the Pure-Nano, named after my pursuit to have the purest water possible in my reef tank.

The Pure-Nano
I’ve been running the Pure-Nano in my tank for 2 weeks now. I am running Filter Floss in the top, Phosban in the middle and Chemi-Pure Elite in the bottom. My tank has never looked better and finally, no more particles floating around the tank!!! Since the original post, I've made a new basket for my 12g Nano Cube as well. This allows you to use a media basket in chamber 1 vs. using the stock sponges.
To Build or To Buy - That is the Question?
After completing this project my first instinct was immediately to start building and selling them. After all, if the improvement was good for me why wouldn’t everyone want one in their Nano-Cube. After thinking twice, I felt that I needed to share this as I would not have been able to build it if it weren’t for the open sharing that has been created on Nano-Reef.com. Below you will find my build notes and process. If you decide that you want to build one yourself you should be equipped with the knowledge to do so.
Key Build Notes
For those of you that want to build your own media basket it is key to have a table saw with a very fine saw blade. I attempted to cut the acrylic by scoring the plastic and snapping the pieces. Because the back chamber is so tight, your cuts must be perfect in order to have a basket that slides directly down the rear chamber. A saw blade with at least 60 teeth is necessary to cut the acrylic without splintering the edges.
The plastic weld used to adhere the pieces together can be difficult to work with. The IPS Weldon 4 is water thin which makes applying it difficult. Imagine applying water to the edges of acrylic without it running over the edges and melting the areas of plastic that you don’t want to glue. An applicator which is pictured in the first photo is an absolute must for doing this project. This allows you to apply very small amounts so that the weld does not run. The weld does not work like most glues, this actually melts a small layer of each piece of acrylic which forms a very strong bond.
I chose to use 1/8” acrylic. Anything thicker than this will cut down on the allowable area to pull water into the media basket. Anything thinner would be to flimsy and make for an inferior product.
The egg crate is nothing special; I bought mine a Home Depot. It can be found in the lighting section. Unfortunately, they only sell a huge sheet of it. The cost is about $12 which will give you enough egg crate to make about 50 media baskets.
Summary of Costs
Sheet of 1/8” Acrylic - $11
Can of IPS Weldon 4 - $15
Sheet of Egg Crate - $12
The Build Process
Step 1 – Glue the first 2 out of 3 pieces that make up the basket clips. These will be what holds your media basket in place and prevent it from falling down into the middle chamber.

Step 2 – Glue the 3rd and final piece that will make up the media basket clips. When completed you will have 2 clips. Set these aside until they are used later in the build process.

Step 3 – Glue the egg crate to the back wall of the media basket. These will serve as your media shelves.

Step 4 – Glue the front wall of the media basket in place.

Step 5 – Glue the Media Basket Clips into place. At this point you have a finished media basket. Not pictured here but I have added a handle across the top which makes pulling the media basket out of the chamber easier.
