Hi,

I had a 20 gal tank in my office that had beautiful plants in it. I let it go and the plants began to died. I cleaned it out and replanted what was left and things began to grow again. I ran out of dechlorinator, so I bought a different brand. Suddenly my floating plants died and my vallisneria stopped growing.

I got a larger tank, put it in the same place, bought some new plants, yet they are not growing, but slowly dieing. I bought a different brand of dechlorinator, but still I have slowly dieing plants. Any ideas? (The light if it is not the same is slightly more than before.)
