Nitrates of 80 is definitely a concern. Though it may be perking up, with nitrates that high, I don't expect the BTA will thrive, and may not even survive.

Just did a 20% wather change a few days ago no skimmer at present time. I am using carbon I have a aquaclear 70 filter
I want to get a skimmer but right now things are tight just bought a new house and well you know how that is. Still looking for a cheap but nice one. I fed the nem a small piece of raw shrimp 2 nights in a row how often should it be fed?
