there is a lot of algae for them, the turbo is full size already too
but what about the fluval clearmax?
Still, return the snails. I have no idea how to use the clearmax.

IM AT 0.5-1PPM PHOSPHATES, MY MONTI IS NEARLY DEAD!!!! HOW DO I LOWER QUICKLY??? I dont have any phosphate removers :((((

Lowering quickly won't help. The damage (whatever it is) is done. Nothing you are going to do will have your tank bounce back overnight. You have to be patient and accept that you will suffer losses.

41 snails?
Clearmax is some kinda “hard” GFO, it’s cleaner, less dusty, comes in small bags made by Fluval I think…I have it somewhere
Yes, OP has 1 turbo and 40 astreas in an 11g.

I know I'm late to the party in terms of giving suggestions, but I'll throw out the solution I would've started with.

The spawn looks a little rough, but not terrible. The monti is likely a loss.

My initial assessment would be the alkalinity. At 12dKh, I'm sure that is a contributing factor.

I would mix salt water, about 5 gallons (50%) with the temperature matched. Use a salt with a lower alkalinity like tropic marine (ref: https://reefstable.com/blog/salt-mix). Then I would wait 24-48 hours before making ANY other changes.

Additionally you should not be dosing ANYTHING during this time.

Additional questions to narrow things down:
  • What is your Salinity?
  • How are you measuring Salinity?
  • What is your temperature?
  • How are you measuring temperature?
  • Have you checked ammonia (usually cloudiness indicates this or bacteria bloom)?
  • How are you measuring alkalinity?

I match temp and everything, if im correct, salinity is 1.026, with a refractometer, temp is 80 :(very hard for me to get it down, my corals have gotten used to it, trust me :(, its also cuz I have 3 windows in my room, and its infront of 2) with a clip on mercury thingy
no
with salifert

Okay...

Followup questions:
What do you use to calibrate the refractometer?
How often do you recalibrate?

I would invest in a hanna temp checker.

Your current problem though is almost certainly temperature. No offense, but while some may have adjusted, it's hard to accept that answer when you have multiple coral dying and that is a common cause.

To bring down temperature, you can set up a fan to blow across the top of the tank. Another way is to freeze SMALL bags of RO water and place them in the sump as needed.

When you don't have a chiller, both of these are effective. I personally use gallon bags of ice for over 500g system and it does the trick.

when should I calibrate? I got it not long ago, and it was pre calibrated(I checked) isn't 80* good though for a tank? isn't the temp range 74- ~82?
