I didn't find anyone using 1 osmolator (Tunze) to work with 2 independent tanks, any thoughts on this would be great. I guess evaporation will be similar in both tanks as water surface, lighting and pumps (same heat produced) would be the same.
I'm now setting up a Calcium reactor (Aquamedic Calcium Reactor 1000) for better calcium and alkalinity.
The upper tank is working just with LR, I'm planning to add some live sand too.
