How big is the tank? You said you had a 50w heater, so I can't imagine it is big. 50 or so snails, and not sure how many are left? All those inverts are nutrient batteries just waiting to release when they die. I'd be damned sure to know within a few how many were left. Most likely they starved and your nitrates shot up. I'd tend to believe the high number from the salifert nitrate test, though I would try and confirm it with another type of test, or LFS store test. 

Ive got a 40 breeder with 10gallon sump with skimmer. Wow yeah i feel foolish to let the snails go unchecked. May do some damage control and pick out empty shells. I will ask the lfs but doubt theyre open today so ill go in tuesday

I have absolutely zero algae of ANY kind

It still looks from your photo like you have very little or no algae growth.  Scraping the glass is a good sign, but not quite the same as the presence of green algae growth.

 

Why did you add the monster-sized batch of snails you mentioned if you had no nutrients and close to zero algae?  Did you have a bloom of a non-green algae?  (tan, red, etc)

 

I'm starting to believe that the current "high" nutrient levels may be caused by snail die off as someone else mentioned....so a new phenomena for the tank.

 

If so, that would seem to confirm the earlier hypothesis that the coral problems you were seeing were related to starvation of phosphate (and maybe nitrate).

 

This also means that any of those symptoms should begin to clear up for your corals and you should start to see some green algae growth. 

 

Stay on top of phosphate and nitrate testing for a while (weeks at least) to make sure what the norms and trends for these nutrients really are.

Well i went with a 20 gallon sized clean up crew from the internet ( forget the site name)... Rookie mistakes lol. So ill keep on monitoring my levels for a few weeks. Ive been doing small 10% water changes to get them down to 10ppm gradually... Hopefully that helps some too.

 

Ill report back in a couple weeks with water test records and all... I appreciate your help!

At least you didn't go with a 40 Gallon size!!  🙂

 

Now you know to match your cleanup crew with your algae growth.

 

(I'm not sure what they base those CUC package sizes on, but I assume that it is a tank of the size named that has a totally out of control green algae bloom. It's definitely not a general recommendation for all tanks that size, even though you can't really tell that from the marketing.)

No joke! At the time i did have a diatom algae bloom so i thought it may still work out... I had no idea how efficient 40 tiny snails would be!

It was partly their efficiency and partly the fact that diatoms

 are a self-limiting kind of bloom.  Once they exhaust available silicates in the water, the bloom is over.

 

So I think if there is/was a problem with your corals it's that the tank was nutrient starved up to the point that the cleanup crew died off.

 

The nutrient spike from the die off may have caused some minor issues, but the main issue that is caused by that is usually an algae bloom not coral problems.

 

I bet if you just keep things stable from here and don't let nutrients crash back to zero that everything will turn around within a few months.
