Nice tank! I started a dirted 1 gallon last year and now my betta is swimming in it. I have no filter but change the water every 3 days. I tried adding some liquid ferts but I think it's too strong for the 1 G and burned my plants. The are only now recovering.
thanks, wow it looks really nice! what plants are those? how did you dose the liquid ferts? I just set mine up two days ago. so I used an eye dropper and drop two drops of flourish into the bowl. -shrug-
also, im thinking of making a diy pvc air filter.
I like it, great job
