Before you put anything in there make sure you test for results. Sometimes if the plants aren't yours or are use to different parameters they wil melt or adjust and not suck up much ammonia. Happened to me. Just do lots of water changes as there is lots of nutrients in the water, algae can take over at this point so be careful.
I've had the plants in QT for a week in my conditioned tap water, so I'm not too worried, the only ones that ever gave me melt issues were the anacharis which have sprouted new healthy growths that I am using in the new tank, the biggest one is roughly 4 inches long.
I'm going to be doing a couple 50-25%s a week until the tank stabilizes more. I'm not too worried about algae, it happens and is natural. If anything the shrimps and snail can feast on it to their heart's delight. The duckweed shipped yesterday so when I get it I'll QT it for a bit and then throw it in, I've heard it out competes algae.
And thank you for the complement :) The columns are one of the most attractive decorations for a tank that I've found, so I'm really excited about it ^^
Yeah, that's the cardamine, I love the way it looks too :D
Just added Nova, I didn't know it was possible for a fish to be so happy! he's swimming every where, looking at absolutely every thing and flaring up a storm!! He even colored up brighter! xD I'm so excited for him <3 love the little guy too much for my own good xD
