That feeding pic was of LIVE brine shrimp lol. It looks to be alot because they are moving, but within 3 mins, all of them are gone. The corals, crabs, shrimp, fish eat them all up and what ever is left gets sucked up by the filter.
I just have the regular fine green algae growing on the glass. I think the trates are back down, because not much algae has been growing again. I have to check again, but when I did a water change I took out more this time and I've been feeding every other day with smaller amounts of frozen.
