My corals are dying

[rock_lobster]

YOur coral are actively dying one water change isnt going to do much. You need to do them repeatedly until you test low nitrites.

Impossible for such low alkalinity level. Just test some fresh saltwater for nitrite ammonia and alkalinity.....

 

[New2dareef]

Ammonia is 0.01 according to seneye

Tank also has rbta a cleaner shrimp, a dozen hermits and a very small clown

Yea try to get them nitrite under control sorry to hear I'm also learning this is a hobby that takes a lot of care and really watching the lvls that was my first lesson also but it will work out there are a lot of good helpful people on here that will take the time and help

 

[New2dareef]

So rock lobster, you recommend more water changes and if so what's safe

 

[rock_lobster]

Yes the nitrite level must be low or zero it is very toxic molecule. I recommend continuing waterchanges until the level is lowered as well as using any water conditioner to neutralize the ammonia/nitrites.

If your coral look to far gone then you may need to remove them or else the process with take a lot longer.

May be you should get a second opinion; have a local fish store, a good one, or a local reef buddy test your water. I don't see how you can keep corals with nitrite AND ammonia in the water....Something is a bit off here. Did you test the water before putting corals in????? I mean how did you cycle your tank in the beginning?

 

[New2dareef]

I installed a mini oxydator to try and help combat the algae problem. Could that be poisoning my tank

Ammonia is 0.01 according to seneye

My doubt is because your salt is Coral pro which has some vitamins and organic which possibly went bad and giving you high nitrite.....I will suggest dissolve fresh salt in RODI and take reading if it comes out like tank water then you need to throw your salt and get a new one. Water change will not help with the same salt. Also read alkalinity of fresh saltwater to make sure your reagent is bad.

In your original post you listed Salinity at 16..then it's converted to ppt...which would give you a specific gravity reading 1.012 which is low salinity. Should have reading of 1.024. Hope your corals make it!

 

[New2dareef]

Tank ran with live rock an live sand for 6 weeks. I used shrimp and pure ammonia. I followed what I've read here so many times until my ammonia read 0

 

[New2dareef]

Sorry I went back and realized in my panic I wrote that wrong. Salinity is 1.024

You said you are combatting an algae problem, also showing ammonia and nitrite which should be zero...are you feeding to heavy possibly..your bacteria colony should be converting ammonia and nitrites to nitrates once you've cycled and shouldn't go back up unless they're overloaded or have died off for some reason...

I have two large rocks in display tank and some rubble in the back refugium. Four weeks ago I got tired of pulling of algae so I pored some peroxide on part of it. It killed off the algae but also bleached part of the rock. I assume killing some of the coralline and good bacteria.
I've taken out the mini oxydator and will do another water change this afternoon with new salt. Clown fish, anemone and cuc all seem to be doing fine. I have a go reactor but not running. Would running carbon in there help detoxify the water?

Killed the biological filter.

Algae can get frustrating. If you do not find the root cause and address that issue then you might see return of the algae.

If you do, start a thread, post an image and get some assist. It could be that you just need to add to the cuc.

Peroxide is an oxidizer also used as an antibacterial treatment, it could've reduced your bacteria colony. If your ammonia or nitrites climb you'll know that's true and you'll need to cycle again or add more live rock (that is what I would do).
