Fantastic scape and a truly great journal. All your journals are great and I am learning a lot from reading them.
I am starting to plan a 120x50x50 and are of course looking for what you have done. And you have done differently at different times. Do you mind a few questions?
At one scape you used two filters with two sets of in-/out-flow. Another time I think you used two filters, but with only one in-/out-flow. And in this scape you used only one (large) filter.
Do you have a final recommendation? With my limited experience, I have found it difficult to get good flow in all parts of the tank with only one in-/out-flow without adding an extra flow pump like many do – but you do not use that?
At this last scape you used the Chihiros fixtures. They sure look good at you can obviously grow plants with them. Do you think they are as good as the previous fixtures you have used? More importantly, how do they look to your eye? – do the plants and colors look great? Obviously that will be subjective, but it is also obvious that you have great taste
My concern is that they are 8000K – quite cold.
You have tried different dosing regimes at different times.
Do you have a conclusion on your DIY ADA dosing experiment? In you Crystal River journal you are in 2014 very enthusiastic about Aquarebell Makro Spezial N and KramerDrak, but it seems your are now mostly doing more common EI?
