Corals dying :(

What’s your test kit saying for nitrate ? Does it matches 37 ppm?

 

[VintageReefer]

What model tester

Larger lps like the former Trachy, and the donut coral on the sandbed will do fine on mysis. Smaller mouth coral like favia, will do well on small pellets, crushed up flake food soaked in water, or powder food like benereef or reef roids

At this point I don’t know what’s right or wrong as for your values. Icp is only as asccurate as the date of the sample. And your results are not close to the icp results

Your test kits reagents could be expired, fouled (water got in them) who knows.

Can you take a water sample to a LFS to get a third opinion and have them check salinity, nitrate, alkalinity, calcium, phosphate, magnesium

Yes, and besides that, you need to learn to interpret correctly the readings from an ICP... Your ICP value for nitrate is close to 37ppm, not 0,2 as you stated on your first post. its hard to make any adjustments if you don't really know what reading you are getting...

As @VintageReefer said, Get your water tested today and lets work from there.

And no Petco is not a LFS lol. Please don’t come back tomorrow and say you had petco test the water. Go to a real LFS

I would first make this solution and check it against your refractometer.

Looking at the lps all closed up it could be something this simple.

Nutrients look fine to me.

No i haven't calibrated the refractometer …my source water i wale water but passes trough 7 stage reverse osmosis …. Yes filters replace regularly every week…

Well calibrate it and recheck your salinity.

I mean it’s good you’re replacing your filters but THAT often? Why? Is your main supply fouling your filters THAT quickly? Every week is excessive unless you’re generating hundreds of gallons weekly and you can’t keep your TDS down. Doesn’t seem right.

No im sorry i thought u meant aquarium filters…
Reverse osmosis only when i see some TDS readings

0.2 was with hanna yesterday… that icp testing was done like 2 month ago

I think thats a good idea going to take it to LFS and check! That way like you said ill get a third opinion

If your corals were doing okay 2 months ago with high nitrates, and now are doing poorly with low nitrates... I think you have your answer. You're starving your corals of Nitrates.

Calibrating the refractometer is a good idea, especially if you use a 2 part dosing solution. They can raise your salinity.

At the least 3 or 4 of those pieces are clearly suffering from bacterial infections. What triggered it could be all of the above or something completely different. First step is to treat the infection as finding the reason will help in the future but not save what's already taking place. I would give every piece in the tank whether it's showing decline or not a lugols bath. That will clean them up and buy you some time to fix what needs fixing.

Thats the thing they where not doing fine 2 months ago issue started before that…

Im going yo check the salt in LFS store just to have a third opinion
