Filter concept: Re-purposed 12 gallon bookshelf
Attached is concept I want critique of. I'm not all that attached to it but I do think it could work. Here it goes...
I have a 75 gallon freshwater low tech planted tank. Lots of fish. No filter just circulation and good water. No holes drilled.
Adding a 55 gallon underneath it. At first I wanted to just plumb it as a refugium/sump. Then I remembered...
I have a spare 12 gallon long bookshelf aquarium branded Mr. Aqua at the time and am now considering using as a 3 chamber filter in between these two tanks.
Plumbing between everything would be PVC/hose combo most likely. I'll have HOB overflows taking water from main display tank into the 12 gallon filter tank and then have that drain into the 55 gallon below.
The 55 gallon would be heavily planted. Fish load in this tank would depend on how well the water quality is in the main display above.
I guess I'm thinking that I could possibly achieve:
1) A superfilter capable for improved water clarity and bioload handling
2) A way to use the entire 55 gallon as essentially another display tank rather than partitioned as a traditional staged sump/refuge.
That being said, it will be heavily planted and capable of more nutrient absorption.
3) Another tank to grow my fish into or use for creative purposes
I'm new to the plumbing but have been studying how to do all of it.
This is just a concept right now that I'd like critique of. The 12 gallon in between is another point of failure I know.
The feed into the 12 gallon long tank would be designed to ensure it runs through most of the media and slows down over the UV submerged lights.
The 55 gallon underneath will be filled lower, maybe to 40. I'll have overflow of last resort directed into my kitchen.
Thinking that I can basically do a lot of the maintenance through the 12 gallon filter also. Not expecting this to "get me out of water changes" or anything of the sort. Just trying to expand and use spare equipment. I have a 7.5 gallon cube that I'd put underneath the 12 gallon filter for drips/add'l overflow.

Reason: clarified freshwater
