Tank is crashing :(

[Craigdillman]

Hey man that really sucks

But from what from I'm reading if your fish are ok and it started with corals and your parameters have been stable the only other thing you Changed that was big was the lights, LEDs are a big change from the T5 specially if you haven't been up on changing the bulbs you could have had a massive par swing from like 300- over 1000 some lights are depending what u got and settings and height , i would start there dial back the lights % if you can or shorten the time they are on

Seems your water is good but with death water changes are never a bad thing maybe try doing a few decent % WCs to see if you can turn the tide

Hope that helps man not sure

Do you do regular small water changes? I just went through a mini crash (tips burning, some coral expelling all polyps) and it turned out my source water was high on chlorine because my RO filter couldn't handle it and it was passing through.

If you don't do changes do you replenish the trace elements?

It could be a lot of things, can you post a picture of the tank and some examples of whats going on?

I hand done a water change in a few months but I do go through a lot of top off water due to evaporation. I was dosing trace elements from aquaforest and didnt have any issues but then I stopped when things started dying.

I'll try to get some pics up for you guys to see

Sorry to hear, iceman86.
A few questions:
Did you measure the PH before and after the addition of the calcium reactor?
Do you have a sandbed?
What light fixtures were you using and which ones are you now using?
What do you have for water circulation?
How much GFO have you been using and how often are you replenishing it?
How long has the tank in it's present state been running for?
Can you post a link to the Walmart nori?

Please post a picture as mentioned above.
I'm not a fan of GFO because it will remove trace elements, so I would recommend a larger (25%) water change sooner than later.

My ph before the reactor is 8.3 and with the reactor it did with it it's about 8.2 and would drop to 8-8.1at night.
I also have a ph probe right in the reactor as well measuring a oh of 6.7
Yes I do have a coarse sandbed.
At first I switched from 2 tek t5 fixtures 8 bulb each to 2 vertex illumina fixtures. My latest set are 5 mars aqua fixtures along with 4 36" t5 bulbs.
For water circulation I have 2 maxpect gyres that will blow the sand around if not turned down.
I run 1000 of gfo and that lasts me about 2-3 months. I have 7 tangs who poop a lot lol
This tank itself has been running for about a year but the live stock has been with me for about 5 years while upgrading tanks .
I tried looking earlier on the Walmart page for a pic of the nori but I couldn't find that exact one sorry.

It's been a while since I posted a pic. Can anyone give me some instructions ?

Have you double checked salinity with another refractometer? I've almost wiped out a tank slowly with a broken refractometer, Just a guess. looks like something is irritating everything as even the trumpet coral looks to be receding.
