I have a 29 gal
tank that i have had for about 2 months. The first month I let the tank cycle and over the course of this last month I have added its current inhabitants:
2 Ocellaris Clowns
3 Cateye snails
2 Emerald crabs
1 Hermit crab
1 Chocolate Chip Star
There are 13 lbs live rock, a couple pieces of base rock, and 16 lbs of live sand.
During the first month while the tank was cycling, I watched as the ammonia and nitrite levels went up and came back down and I haven't seen a trace of either since. In this last month everything has been fantastic. Everybody in the tank seems very happy and enthusiastic about their new home & they get a 20% PWC
every two weeks.
So what I have been wondering about is that I have never seen any amount of nitrates. Ideally you want to keep the nitrates as low as possible but to never see any amount seems strange.
What do you guys think?
