Purple and Green Frogspawn have sweeper tentacles that can extend 2″-4″ at night and sting nearby corals. Hammer Corals may be placed next to other Euphyllia species such as Hammer Coral and Torch Coral as they do not sting other Euphyllia. Mount the Purple and Green Hammer Coral using IC gel glue, or putty, on an exposed rock or ledge in the lower two-thirds of the aquarium where they will receive moderate currents and low to moderate lighting. Leave 2-3″ around this coral as it has tentacles that can sting nearby corals at night. Although symbiotic algae called zooxanthellae hosted within them supply some of their nutritional requirements through photosynthesis they do benefit from supplemental feedings of reef roids, and mysis shrimp. The Purple and Green HamFrogspawnmer Coral require moderate water flow and moderate lighting (PAR 150-250). T5’s, Metal Halides, or LED’s can all grow Hammer Corals when the proper PAR levels are provided. We recommend a 14-20K colour spectrum for the best colouration.
Care Level: Easy
Lighting Requirements: Moderate (PAR 150-250)
Water Flow: Moderate
Range: Fiji, Indo Pacific, Australia, Solomon Islands
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppmIt 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.Fraggle Reef 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. Acclimatising your new corals is an important method to make sure they survive and thrive in your system.
