Voted for tank No.1 although i do agree with a lot of the people here that no.3 could have had a good chance of winning this month if only the water was clearer... then again, maybe he/she has fish in there that prefer those sort of murky type conditions???
I don't see why everyone is freaking about #3.. I would assume nobody would take a picture of their tank for a competition if it wasn't supposed to look like that.. I have seen plenty of P and natural tanks with that look, and numerous tanks with high tanin levels as well. Even if it was clear, I still would've voted #1...
