My 2 year old son threw a container of fish food pellets in my tank as he was being baby sat, I didnt know of this until I returned home 2 hours later and my yellow tang and damsel have died and my corals seem to be ok for now. I have a 125 gallon tank and I did a 40% water change and removed 85-95% of pellets. Im waiting for water to clear, Im runnung 2 canisters and 1 uv light, protein skimmer and 2 pumps. WHAT ELSE CAN I DO? THANKS......
