lol DIY Test Tube Holder is badass
I think i'm going to have to add that to my list of things to do. Tank is looking quite well and you seem to be doing pretty darn well on budget too. Another piece of driftwood or some rock might fit in too if you like that look. Are you using peat to try and lower the ph or darken water, or? Plan to add any fish?
The tall plant in the middle (can't make out quite what it is) sticks out like it is now. maybe try moving it back (if there is room), and add stuff on its sides that are closer in height?
Please keep posting pics! I wanna see what ya end up with.
