Coral keeps closing and dying.

Thread 'Tin Leaching from Common Plastic Tubing and a Very Inert Tubing that I Found' https://www.reef2reef.com/threads/t...-and-a-very-inert-tubing-that-i-found.793590/

Well we are jumping to conclusions here because all our tanks are the same. We all should see tin then and I show none from ICP results 2 days ago. Do you have flex tube off your pump?

Perhaps it effects some tanks differently?
Water change schedule, cuprisorb usage, ect. Could be a lot of factors.

Cuprisorb will take care of it.
Changing pipe won't help unless you use hose. Maybe silicone?
There is a thread about types and how much different types leach. Let me see if I can find it.

Just seems like reaching at straws but would it be leeching after years? Cause I’ve had the tank since 2019

Hey guys I’ve been in the reef tank hoppy for a while now but I’ve been struggling with 1 thing. Coral every time i purchase a piece of coral it does great! Everything is opening and they look super good. Then what seems to happen is that it closes and stays closed. What could be the problem for that? Why would a coral go into the tank for a few weeks its great then something seems to happen and they close and never open again.
Parameters are linked with an icp test i did.

Salinity 1.026
Ph-8.1
All-9.3
Calcium 350
Magnesium-1300
Nitrates-6
Po4-.1
Ammonia-0

Tin always seems to show up on ICP tests- not sure why, but the calcium needs of SPS and anything skeletal is critical and you should be at 400-440 range.
When you do tests yourself- what tests are you using ?
Your lighting may be part of issue as the Kessil A350/360 offer great shimmer but lack penetration of tank. I believe I see One powerhead only which may suggests inadequate water flow which keeps debris off coral, delivers food and oxygen.

I'm also leaning towards light/flow. To me, if water parameters are in line, which they seem to be more or less, then it comes down to lighting and flow.

There is 5 power heads in total 2 MP40’s on the side and 3 apex wav. And I’m working on getting the eco tech lights.

Ok - my bad, from reflection, I only saw one

Those wav pumps are powerful huh? I got 2 and a mp40 in my 75.
What size tank is this? Sorry if I missed it.
250 par at the top is not horrible. Most sps will do okay but some may need more. It won't kill them but may brown/pale out.
Calcium is a tad low but average ocean is about 350.
Alk is fine, maybe more than some people but also some run it higher.
Are you able to keep alkalinity stable with the magnesium so low? That number should be at least 1350.

Did ICP confirm your salinity?
How are you controlling temperature?

Oh yeah 100% i run them at 35% the tank is a Red Sea 750 xxl

Ok, Salinity, and how are the heaters controlled.

My other question, has alkalinity been stable with magnesium being low? Should be 1350.

 

[MACHO]

Heaters are controlled from there own modules then backup from the apex. Salinity is from milwauke and apex probe.

Magnesium is always a little low. Alan is pretty stable

Have you checked potassium? How often do you do water changes?

Normally i do water changes once a week but haven’t been able to for 3 weeks

Potassium is in the correct position
