Hey all...I finally ran out of Spirulina Algae Wafers a couple weeks ago (I dont go through them very fast haha) but when I went back to Petsmart to find some more, they didn't have my nutrafin kind. All they had were two different kinds and they were both in bags. (Hikari and Wardley I believe) SO this is a several part question. #1 What type and/or brand do you prefer and why? (are there other types besides the spirulina?) #2 Does anyone use a brand that comes in a BAG instead of a little airtight container with a screw on lid? If you do, then does it work?? they looked kind of crumbly to me... #3 Which of your fish do you feed the wafers to...and which of your fish actually end up eating them?
