hi All,
I have a 75G tank with a Fluval canister filter. It has been working well for just 4 fish right now. But I want o now add more fish and contemplated using FX6. But I want to go for a SUMP instead, that will be better for regular maintenance. Please see the attached image for the design. I will be using a 29 Gallon Aqueon tank for the sump. The drawing is not to scale. Please suggest if this design looks good.
I think this will work just fine, glad to see you using the anoxic filtration. My sump is set up in a similar way also.
You should place the floss or filter sock above the media as it gets dirty quickly and it will be difficult to replace3 the floss where it sits now.
Also this is not anoxic filtration. There are normal levels of oxygen in this system
The Anoxic part is based on Kevin Novak's videos. The idea is not to have low oxygen levels in the water itself but rather at the core of the Basket. So the idea is that normal aerobic bacteria will populate the exterior of the BCB basket and use up significant oxygen thereby reducing the oxygen levels for bacteria in the core. This in theory creates anoxic (low oxygen) conditions for such bacteria to populate. I don't know if this will work but based on all the videos by Kevin Novak this is how he does it. So I want to try it out. If there is a better way to implement an anoxic filter I would love to try it
With regards to the mechanical, I will be using a lighting diffuser as a base for each foam and probably use long zip ties as easy pulls. using filter floss, in the beginning, will render coarse and medium foam useless.
Got any pics of your sump with anoxic baskets? Would love to learn from tried and tested designsQuote:

ooh yeah, I found this on youtube yesterday. Was not sure if it was your channel. The entry is definitely noisier than I would like. That's the reason I have a thinner chamber in my design so the entry can be fully submerged for quiet operation. Otherwise, my wife will not approve it. The Kitty litter I got is the same as you use but it is a lot dustier and also mushes down easily in water. That's why I have not added it to the tank yet.
The sump is much quieter than in the video. The tank is in the living room and my wife too would say something if it was noisy....
+1 for anoxic filtration! I cut 2 300 micron filter socks and filled them with oil-dri (baked clay) and seachem fluorite red (iron) and dropped in sump.
