The Riddler Mycedium will bring a good contrast to any reef aquarium as it encrusts over the rock. Mycedium Corals have sweeper tentacles that come out at night so leave several inches between them and surrounding corals. Mycedium are close relatives of Chalice and Echinophyllia but should not be placed directly next to them as they can sting each other.
Lighting & Flow Requirements:
The Riddler Mycedium requires moderate water flow and low to moderate lighting (PAR 80-200) to maintain its color. T5's, Metal Halides, or LED's can all grow Echinophyllia & Chalice Corals when the proper PAR levels are provided. We recommend a 14-20K color spectrum for best coloration.
It is important that proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are maintained. Raising magnesium levels gradually up to 1400-1600 ppm can help to combat algae outbreaks, just keep CA and Alk in line as you raise the Mg. Nitrates should be below 10 ppm and phosphates should be below .10 ppm. We recommend doing a water change when Nitrate levels rise to 10 ppm. It is important to replace your phosphate media when phosphates rise to .10 ppm. Media Reactors make the most efficient use of your phosphate media by fluidizing it.
Vivid Aquariums uses and recommends dosing pumps to automate the dosing of additives and keep your levels more constant. A dosing pump can alleviate the chore of manually dosing your aquarium with Ca, Alk, & Mg 2,3, or 4 times per week and will benefit your aquarium by keeping your levels constant through frequent small additions of Ca, Alk, & Mg. Our tanks all progressed when we switched from 3 manual dosings per week to 70 automatic dosings per week and we got a lot more work done.
Mount the Riddler Mycedium using IC gel glue, or putty, on an exposed rock in the lower half of the aquarium where it will receive moderate flow and indirect light.
Vivid Aquariums recommends feeding Mycedium, Echinophyllia and Chalice Corals with Oyster-Feast, Roti-Feast, and/or cyclopeeze. Target feeding gets the corals fed using less food while keeping your nitrates and phosphates lower.
