With a 4" sand bed and adding the power heads how much did you disturb the sand. When did you do your testing? before the lose or after? If it was before how long before you added the new power heads? My guess is you release a lot of stuff in the sand bed.

Is it possible you had a nitrate spike? you have a reading of 5 is this normal for your tank?

When you changed your power heads did the flow increase disturb the sand bed?

i think i found the problem. i was focusing on the fish and inverts and missed something obvious. my magnificent anemone was missing. found him chewed up in the pump. dont know why the testing didnt show anything wierd though. time for a new test kit im thinking. thanks for all the suggestions im hoping that was the problem. the powerheads dont seem to be disturbing the sandbed noticeably

Anemone chewed in pump, darn. Glad I went closed loop, no powerheads in my tank. I hope thats the cause. Sure is alot of fish$$$ to lose all at once

it was a painful loss but i was way overstocked though now i can work more on my corals without the fish in the way. turns out there are 4 fish left. a percula, a scooter blenny, a yellow spotted tilefish and a citron goby. hopefully they make it to the new tank

Bandit, important to guard your intakes even with a CL.
