Some time ago I stumbled upon Dr Novak videos about anoxic filtration. Couple months ago it inspired me and I decided to reset my 240gal tank and install plenum and no3 reactor.
The effort and work finally paid off. I have my tank now running on auto-pilot so even after 10 days vacation with tank unsupervised, my nitrates are below 5ppm. They used to raise to 40 or so in the same period previously.

I encourage everyone to look into anoxic filtration options and perhaps get something learned from my short video about installing 12 sq.ft plenum in my tank. It's really worth it.

My tank water parameters after 10 days with no wc are solid:
pH 7.2
Ammonia 0
Nitrite 0
Nitrate

Plenum installation in 240gal (900L) aquarium. Special thanks to Dr Kevin Novak, PhD for inspiring videos about alternate filtering options and anoxic filtration tools and methods.This build was inspired ...

A $15 thermostat add-on (upper right) improves the automatic water change system to level water temperature in both tanks before transferring it to main tank. The main system controller recognizes thermostat presence and displays heating action accordingly (lower left). User can leave it unattended and water transfer will begin automatically once temperature is leveled.

Platinum R240 tank+hood+stand set by ATM: post delivery inspection, adaptation for freshwater use and seal testing. It's solid tank made in US, comes with matching stand and canopy equipped with touchpanel, thermometer probe, clock & timer to control built in canopy multicolor LED lights. Tank comes bottom drilled for center 2in drain and two 1in return/emg bulkheads. The internal jewel box type overflow is ready to serve saltwater tank but here I used it to conceal drain and return pipes from two out of three canister filters. See comments under photos. Thanks for looking.
