Images are only for color reference. I don't have all the pictures of the kits completed yet. You will receive the full kit as seen in the black and pink pictures with all items included, but in the color you select. 

PLEASE NOTE: 
You will need a stronger return pump than stock for the chamber 2 basket. It simply isn't powerful enough to move the water up and over the flow director. I recommend something rated at least 185/700 gph/lph flow rate. The Sycce Syncra Silent 0.5 or 1.0 are great drop in options, but the Jebao DCS-1200 and 2000 are far better options, but do require modifications to fit the chamber.

3DOcean in-house designed and printed upgrade kit made specifically for the Fluval Evo 13.5g nano reef aquarium. This kit includes both media baskets for chambers 1 & 2 as well as the chamber 2 backwall plug, 2 1/4" rfg nozzles for stock the dual output lines and all 3 chamber covers. Everything you need to get that Evo or Spec flowing and filtering to it's best potential. 

These designs came from my personal desire to improve the flow and filtration in my 2 Fluval Evo reef aquariums. Finding the shortcomings of the stock setup and other aftermarket options available, I made modifications to each and every area that needed attention. The results were far better direction of the water flow, snug fit to not have those rogue jumper fish wind up in an area you can't reach them, and ease of maintaining your media. The baskets have 4 removable and interchangeable shelves each that you can utilize in ways the others don't allow. They too fit more snugly and help seal off the chambers, combined with the flow director built right into the top of the baskets, you now have water that flows over all media in a tiered fashion. Still allows the lowest area of the chamber to be utilized for ceramic bio media or rubble rock. You have the option for a wider output opening for use with either a protein skimmer in chamber 2 or media like the stock sponge block or open flow chamber 2 baskets. The second chamber basket allows for use as a refugium, media basket as well as other configurations. The chamber 2 backwall plug is also included in this bundle, no need to purchase a separate item. Please note, you need to maintain slightly higher water levels in the rear chambers to create the loop to push water up and over the director in the chamber 2 basket. Instructions and suggestions are included with the package. Also fit the Fluval Spec 16 aquarium as the chambers are the same. 

These items are typically printed to order, which is reflected in the ship by date. I run several machines to ensure they are made prompt and have little to no delay.
