Just an update I got a crash abt 1-2wks+ ago after my rbta dissolve & my tank got infested with red slime(never change water for 3wks) only survivors are the purple/white flower pot, pipe organ(my fav) another green flower pot, my cheatos & my strawberry crab. Since then I've restock my tank again these few days and ordered some 120 degree led lens from deal extreme because I feel that the light is too concentrated at the center of the tank from my par38. I'm looking forward to getting the Jebao wp-25 in SG as I do not think I have enough flow for my new chalice.
