I converted my 55g tank from a non-planted to a planted tank on Saturday. I drained all the water, removed the old gravel, add NEW gravel, planted the tank, then filled it back up with new water. Now a new cycle has started!!
I added a new filter to the tank 2 weeks prior. I added some media from my old filter to the new filter, and let the sponge from the old filter sit in the tank until I drained it on saturday to do the change (the sponge from the old filter was huge and didn't nearly fit in the new filter....it was the same size as the new one).
Ammonia was at .5 (I think as I am not at home, but it was 1 color above 0) and nitrite was at .25. Some fish were gasping for air at the surface, so I did an immediate 40% pwc, no gravel vac. This morning Nitrite was near .50!! I did a rush 20% pwc, as it was all I had time for before work. They seemed better after that but I am sure it won't last long.
So my question is, can I do 2 pwc in one day? For exampl;e, since I was only able to do 20% this morning, can I go home and do ~40% 10 hours later? Man, I hope this is a quick cycle and these plants step it into high gear to help me out!!
