So i had bought a long tentacle anemone which was doin fine in my tank and after like 3 or 4 days of buying it i had a algae bloom which i had no idea how fix until yesterday and i open my tank to put a peppermint shrimp in and i saw white chunks floating and i got worried and i still can see anything so i do a small water change like 5 gallons once i do a dead/shredded anemone snd dead clownfish floats by so scooped everything up and for sum reason my watchmen goby is fine but how do i clean this tank now since i guess my anemone nuked it i have activated carbon in it already
