What can I do to improve my tank?

I have had a 30 gallon tank for about two years now. I have just added some soft corals like zoos and mushrooms. I have about 50 or so lbs of live rock and sand and crushed coral for a sand base. I run an Marineland 350 power filter and two power heads. My fish include 2 true percula, 1 damsel, 2 Banggai Cardinals, 1 Firefish, 2 Peppermint shrimp, 2 Camel shrimp, 5 snails and A Bristle Sea Star. Do I need a protien skimmer? All water levels are in the ideal range, except the Nitrate level. I cant get it to drop below 80ppm. Any recommendations would be helpful. Thanks

 

Hey, just a heads up, the more threads you start the more confusing and difficult its gonna be to help. I have replied to one of the other threads. If you can answer some of the questions I'm sure we can help you out.

 

k thanks. new to here.

 

no problem Just people will post different things on different threads and it will get a lot of doubling up and easy to miss things.
