I have noticed this starting to grown in my aquarium the past few months and was just wondering what the best way to get rid of or manage this?

That is red slime algae. It's most commonly seen if you are using tap water, are overstocked or are overfeeding. Overstocking is a problem in your tank. The trigger needs a 180 gallon tank:

Undulate Triggerfish

The lion requires a 120 gallon tank:

Saltwater Aquarium Fish for Marine Aquariums: Volitan Lionfish, Colored

Those fish are way too large and eat way too much for a 55 gallon tank. Your water quality may be suffering from the inordinate amount of waste they produce and the amount of food you are required to feed them.

Red slime algae is also commonly seen in tanks that don't have enough flow. Do you have enough powerheads?
