My biggest fear came through today,I found my new sebae sucked up into the intake for that cursed canister filter(using it for water flow)
I turned the pwr off,but it was beyond saving

What was once a big beautiful creature was reduced to a shredded mass.
I have no carbon left to run,so I'm doing a water change.Anything else I should do?I have 3 pwr heads and a skimmer running,havent tested the levels yet.
