I have a Nuvo 30L, the 36" tank.
Tank has been up for 7 months.
Added pair cardinals at 2 months
Added fire shrimp at 4 months
Added pair percula clowns at 5 months
Tank has around 20lbs live rock and sand bed.
CUC - Nassairus, nerites and hermit crabs
Here's what happened:
Thursday 3/12 - weekly 4 gallon water change check parameters - okay
Sunday afternoon 3/15 - All fish accounted for.
Sunday night -female clown not seen
Monday night - go looking for clown. I have egg crate on the top with some cutouts; found clown swimming with the pump. Must have jumped and luckily landed in the sump. Removed the pump to put her back in the tank. Noticed that the pump had some junk on the input grill on the bottom. Cleaned pump. After cleaning, noticed that the pump was shutting off and on. Removed pump again and noticed a nylon thread (from bag of sand) in bottom of impeller. Removed it, now pump blows breaker. Just run power heads overnight.
Tuesday: Go to LFS for new pump. They don't have anything suitable. Tuesday night put in my MJ1200 used for mixing saltwater in the tank.
Wednesday: order pump online Sicce 1.5.
Thursday: Leave on a trip; wife has feeding instructions and she's done this before. I have auto feeder which will drop minimum food twice a day and then feed 1/4 cube frozen mysis.
Monday Night: wife picks up at airport; bad news. Sunday morning clowns were swimming at the bottom not looking good. Monday morning found 1 dead clown and 1 dead cardinal and no one else is seen.
Tuesday: Found the other dead clown. One nassarius is on top of the sand not moving. Think he's dead but he isn't. His snorkel seems shorter than normal. Two nerites on the sand; also not normal. Check parameters; ammonia, nitrates and nitrates all zero. Kh around 7. Did water change;
Fire shrimp is still alive; two nerites on the sand bed were dead. Still see hermits moving around.
LFS points me to measuring voltage in tank. MJ1200 pump puts on 30 VAC skimmer puts out 16 VAC. New Sicce pump puts out 16 VAC. There are other threads on here about voltage and ground probes. Sounded like most people don't think that's a problem. Not sure what the AC current is in the water.
So any thoughts on what happened? The biggest change was the pump. Going from the 450 gph Nuvo stock pump to the MJ1200 rated 250. (Power heads were running.)
