I have tinkered with several setups in 2 different Biocube setups... From both intank media baskets, tunze skimmer and everything inbetween.
I finally have a setup that I am happy with completely. It enables me to do zero water changes and very little maintenance.
This pic is slightly outdated, the skimmer has been moved into chamber 2 next to return wall. Also, I added my dosing unit and return line into chamber 3 since this pic. And return has been updated since this.
Soon to be updated is the biocube skimmer to a lee's counter current air powered skimmer - I really like the air driven skimmers on these tanks... they are plenty strong, much smaller space consumption, and oh so much quieter. I had to modify the biocube one to get it to perform the way I like it is in my build thread.
chamber 1: heater, ph probe, marinepure balls in the bottom
chamber 2: custom removable filter pad, refugium with kessil H80 lighting from back side, modified biocube skimmer
chamber 3: ATO, dosing lines, temp probe, sicce 1.5 return slip in Y locline into 2 random flow nozzles
Dosing Aquaforest component 1,2,3 and my nitrates are running from 1-3ppm and phosphates are undetectable on hanna checker ULR.
So that means why water change? And I love it!
I will be doing a detailed update soon to my build thread to further explain how it all is working and some lessons learned. But after being told it wasn't possible to run a Triton style system in a Biocube I took the challenge and quickly realized you can acheive this leaning more towards the Balling method...
