Sick Maroon Clownfish, Dead Yellow Tang

[erdoclovefish]

Set up a 90 gallon tank about 5 weeks ago. Cycled w 90 lbs of cured live rock from an established tank. Used Coralife salt, Carib alive sand (80lbs, 4 inch base) have a Megaflow 3 sump w a Rio 2500 watt pump (594 gallons/hr) and a Coralife Needle Wheel Protein skimmer (125 Gallons/hr). Also have a second powerhead in the tank cycling about 294 gallons/hr. Used tap water initially and used Prime Day #1 and Stability daily for 7 days. Also have Chempure and Chempure elite filter pads in my Sump. Bioballs removed. After my cycle, I added a Dwarf Lionfish, Maroon Clownfish and a Yellow Tang. OK, I didn't Quarantine . Diatoms came out about 1 week ago (About the same time I added a 9W Uv filter to my sump). Since purchased 10 Black snails, 10 blue leg hermits, 1 Red Leg Hermit, 4 Turbo Snails and 1 Nassarius snail. Tested SG, pH, Ammonia, Nitrites and nitrates almost daily for 1 month. Temp 78 degrees, pH 8.3, SG 1.020, 0ppm Ammonia/Nitrite and Nitrate. Three days ago I went to a local aquarium to pick up the blueleg hermits and was told I should also be testing alkilinity and Calcium and use a buffer daily. Day 1 I tested both (DK 7, Calcium460. I added the buffer and ......My Yellow Tang died the following day. Now the Maroon Clown has white spots on his side that look swollen. Retested all my parameters and they're all the same. Performed a 25 gallon water change today. Any suggestions? Is this Ich. Tried adding decent photos but don't know how to.

Lets start with more water flow first. The sump pump after head pressure losses is probably around 400gph. Combine that with what I would assume is a maxijet 1200 with a probably partially gummed up inlet strainer working at maybe 200gph and you've got a measely 600gph in a 90 gallon tank. That's not a lot of turnover at all and if your surface agitation is poor or even non existant, you could be suffocating your fish. Are any of them breathing laboredly or acting lethargic?

For pics, most people choose to host at www.photobucket.com and then link pics from there. Underneath your thumbnails in photobucket will be a tag starting with IMG in big brackets. You copy that code into the forums and the pic opens up here

I'm gonna chime in with SkiFletch here. Another possibility is that you just ended up with bad stock, or that they died of shipping stress.
