Not neccesarily, I used a filter pad out of my established tank which is cramed with de-nitrifying bacteria, and only used cured LR
and and 40 lbs of LS
seeded with some from my tank.
I did see a small spike of trates, but they onlky got up to about 20 ppm
, now they are at zero.....
I agree, it is hard to beleive that it is going this well, I have rechecked it every day for a week and even had the LFS
check it. Strange but true......
I have also done two 10 % water changes.
We will see what happens, I plan on adding 25lbs of LR
today, and as long as nothing spikes I plan to add the pair of black percs in the next week after that.
I will have pleanty of water available for quick changes in case of any apikes.
