75 gallon stocking list

[JoeJawz]

Hello I am JoeJawz and im new to Manhattan Reefs. I am a later beginer to fishkeeping. I have had freshwater tanks for about 7 years now and they have been doing fine. I got a 75 gallon saltwater tank a year ago, keeping in mind that bigger tanks are better. I cycled it for about a month. It has about a 1-1 1/2 inch deep sandbed and about 50 pounds of live rock. I have a Current USA Orbit Marine LED Saltwater Reef Lighting System. For filtration I have a Remora Pro Protien Skimmer, an Emperor 400 HOB , a UV Sterilizer, and NO SUMP (gasps). i do weekly 15- 20% water changes. I plan to get an RO DI soon. Im just getting corals. Here's the list of fish and coral I have:

Coral:
2 Green Ricordea ( one is actually grey/ blue but was sold as green)
1 Candy Cane Trumpet
1 Finger Leather Coral

Fish:
2 Blue/ Green Chromis
2 Pajama Cardinalfish
1 False Percela Clownfish (used to have 2 but one killed the other:shocked1
1 Bicolor Blenny
1 Sailfin Tang (it is only 3'' long and plan to sell it at 6'')

So I have 2 questions. First, could i get more fish and is so what? Second, I have had a little Nitrate problem. Only 20 ppm but even with water changes and it is getting annoying. Thanks

welcome to mr.
buy an rodi it should help with nitrates and more.
personally i would add more rock, the bacteria that lowers nitrate is in the rock.

Ok thanks. It will look better with more live rock anyway. Now assuming I do get the RO DI system and more Live rock, could I get any more fish, or is this enough?

I also would like to know if i could get any inverts. I already have a pistol shrimp but it bides all the time
