Trying to plan out filtration chambers of fluval evo, any help would be appreciated.
I’ll refer to them as chambers 1-3, three being top and 1 being the bottom in the photo.
Currently I have return pump in chamber 3 and plan to put an ato there eventually.
Heater in chamber 2.
And 3D printed media basket in chamber 1. Currently running floss at the top, then once my cycle is done chemipure in the middle and then a bag of tidal 35 matrix in the bottom of the first chamber.
I want to try and run a refugium but can’t figure out the spacing for everything to fit it. Also going to eventually get an ai prime and mount it near the back there.
So basically 2 questions, one is a refugium worth it for a nano tank, and two would you lay it out.
Thanks in advance.
