Yes very sad indeed :( I'll be heading out to find a blenny and goby this afternoon. I might try a pleco but im not sure how effective they will be.

thanks. Yeah my first instinct is to replace everything but then im alittle gunshy after loosing so much $ and fish. I'm planning to buy a blennnie and goby this afternoon. I'm considering a pleco, but I'm not too sure how effective they will be.

Aren't Plecos freshwater fish?

Sorry for your losses. Restock slowly. As well, before you spend a mint in new livestock, I would invest in an RO/DI unit. That may solve most of your algae issues.

Hmm good point. I'll look into that. how much would a decent set cost?

I've been using this unit for 2 years now, changed the media once and it's still great, plus if you buy a bit more and you get your order to hit $200.00 you get free shipping!:mrgreen:

Thanks! I've tried just about everything else but this.

What did you raise your magnesium up to? What is it at now?

I actually went for 1600 ( I followed the 100/day as the thread described) and left it like that for about a week. The fish didn't have any ill affects. However I lost a coral and my snails seemed to be affected. The Bryopsis turned pale to white and I pulled out as much as I can during the treatment. The Hair algae didn't seem to be affected but I pulled those as much of that out too.

I"ll have to check what it is now but I assume that it would be much lower. The fish also wern't exhibiting deteriorating charachteristics. It was like they were totally fine one day and a few hours into the next day they were dead :(

I am also skeptical that it was oxygen that caused it, which is why I asked about the magnesium. I'm wondering if you caused a big change in magnesium when you did the 30% waterchange which then may have been the culprit...?

You did say that you just changed salt. Is this the first waterchange you've used it on? Maybe it's a dud pail...

Yep I switched from Instant Ocean to Red Sea Salt. This is my second time using the salt. I did a 30% water change with the new salt before the Magnesium treatment. I didn't realize that the salt can be bad. I did exactly what I did the other times I've replaced the water. before the Magnesium treatment I was doing 30% water changes every two weeks.
If its not the oxygen levles, then I'm completely stumped, aside from the salt and the skimmer not powering up right there really isn't much different that I normally do.
