Reef Roids are great, I only feed half level dixi cup spoon twice a week. Increased color and polyp extention of all my corals (SPS, LPS). Many people including myself have been able to keep hard to keep corals like Gonipora with Reef Roids. I actually soak my Cyclops and Roids in RO water for about 6 hrs (Allows the Cyclops to re-hydrate so there is more chance in them sinking rather than floating and going down the weir) and then I feed before bed and turn skimmer off and then turn it back on in the morning (Removal of filter sock/media recommended as Cyclops would just get caught in it) . Cyclop is also great. I don't compare them as they are different food for different purposes. As far as costs go, i know its pricy but you do pay for what you get, I use about 2 tubs a year. Reeflections Aquarium sells Coral Snow, Cyclop Eze, Reef Roids, Baby Brime, Napali, Rotifers , Seafood, ETC, ETC and more recommend you talk to them as you are in Vic. Hope that helps.
