This is the outside tank which some of you might remember, as of today. I am going to keep it going, with insulation and cover. It needs some new lights now, its been going on sunlight since late April but has slowed with the fading light. Its 250l, diy Co2, soil, sand and gravel, I give it some trace fert every 2 weeks and a few root tabs sometimes. Some algae but nothing that the algae crew cant cope with. I give it a big trim when I cant see the fish. Its been pretty heavily planted from the start with hornwort and egeria densa, but I have replaced them over the months, Its more of a plant collection than a design, but I think it looks nice.
