Dying fish

[nick76lebanon]

I didn’t really know where else to post this but it seems like every single time i dump in phytoplankton to my tank i have fish die. The first time i did it i had a coral beauty angel die, i didnt put any phyto in for a while and everything was fine, the next time i added some my jewel damsel died, didnt add any for a while and everything was fine and then last night i added some and my yellow tang and damsel fish died. Is it possible this is all some big coincidence?

It is very possible that bottle is rancid, toss it if you haven't already.

Was this all the same bottle? For sure toss that. Would be an odd coincidence.

when in doubt throw it out

I went ahead and threw away the bottle. Does anyone know how to check if a bottle is rancid for the future? Just so i dont buy another one and lose more fish. Also thank you everyone for you help!
