Bro,I only pour in brine shrimps and 5 in 1 coral food weekly,to avoid ammonia spike as nano tank water perimeter is very unstable if care is not taken.I also off the skimmer only during feeding time.as for the wave maker,I will switch on and off every 10 min,so that the food can pass around to reach the corals.
As for fish,still thinking of wat to get!!! I will take Into consideration,that if a fish will to die,there is no way I can take out,because my tank is heavily stock up with corals and rocks.this can also cause ammonina spike too.
