Just a minor change. I have extra HC so I am trying that in the "front". It really doesn't have a front but my viewing angle will be what I call front and photograph as the front. It may or may not carpet, I doubt it but I have done it before. I am putting plants in back that you cannot see that I like the emmersed growth. However, I may put some bog plants in instead, just not familiar with them.
The only problem I am having is evaporation. I need to drain it to get an idea of how many gallons, or how many fractions of a gallon it is. I get about 50% evaporation in less than a week. That is not problematic for anything totally under water or above water, just the emmersed stuff as it keeps transitioning from one to another.
Not so different pics:
I also made this for wifey, very low light plants, will probably get a small LED and move it elsewhere.
