No3

[reef tan]

Didn't test No2 as no have test kit...but No3 is zero running on bio pellets during cycling. Does it means No2 is within parameter?

Anyone to help with my dummy question...or anyone stay at Toa Payoh that can borrow No2 test kit..

You can skip the N02 test kit but is more important to have the amonia test kit so that you are able to check the start of the cycling and end of the cycling when the amonia fall back to zero.

You need not run your bio pallet during cycling as this might hinder the whole cycling process. Maybe run it after the whole tank cycling process completed, after you do a water change.

Thxs bro Harle...this is a setup by AM, and tap water was used! And bio pellets did great job handling No3
