Cannot keep inverts alive...

[Markster]

No metal in the tank or near it that could interfere. I have copper in the utility room cabinet for a hospital tank but have not used/opened it in over a year. Measured the pH last night so was not in the morning.

75 gal RR oceanic, 30 gal sump with refug (need to restock the macro), two 175w 14K MH, two 65 W PC actinic, and two 65W PC 10k. Use Red Sea salt (white bucket with orange lid), Remora skimmer, Knoblin CO2 reactor, UV sterializer 15w bulb, 65 lbs live rock, two inch fine sand, use a RO/DI for top off and water changes, feed daily with frozen food mix, use algae sheets for the herbivore fish (one 4" orange shoulder tang, one 3" sebae clown, one 2 1/2" coral beauty, one 3" foxface and just added a 2" clown fairy wrasse. Mostly soft corals with a very large frogspawn and red bubble tip for the clown.

any chance aluminum foil has come into contact w/ the tank?

[Markster]

negative - only use that on the toaster oven.

I had over 100ppm nitrates and kept many inverts alive for over 4 yrs. Including cleaner shrimp.

Agree w/Don. I've had high nitrates and no problems w/any inverts. I'd bet the culprit is some kind of contaminate.

I had powerhead burn up in my tank. It killed every snail, hermit crab, clam, and every other invert in the tank. Fish and corals were ok. The problem persisted for weeks, until I did a major h2o change and ran carbon continuously.
