Need help what am I doing wrong?

[Willy43]

My tank is seven mouths old every thing was going great all corals was growing and seemed happy. Now it looks like there starting to die. I have one that doubled it size then it died.



Phosphate undetectable with my test kit

Nitrite undetectable with my test kit

Alkalinity 8 tested with Hanna Checker

Calcium 410 to 420 tested with Red Sea

PH 8.4



I use BRS two part and dose every day I have a very low bio load so I dose Red Sea Coral Colors ABCD ones a week at 4 ml and Red Sea Reef Energy A&B ones a week at 4ml. I use SB Reef Lights they come on a 7 am with low blue and I ramp up to 12 with the lights set at 85% blue 32% white that runs till 5pm and then ramps down.

What am I doing wrong? I have some green hair algae.

What test kit do you have?

You corals look like the are starving. Were you feeding the lps?

Nitrates should/could be around 2 to 5 ppm
Phosphates around .05 to
.20 ppm.

Ther phosphate number is the one I was having problems with. It also the most debated. But you do need phosphates.

I feed around twice a week with BRS reef chili I feed the fish every day with marine S twice a day

I was wondering if that is what I was doing wrong.

I run gfo and bio pellets should I stop running them for a while and see what happens?

Tank may be starving with no Po4 or No3. You need some of both for corals to flourish, especially LPS corals

 

[saltyfilmfolks]

Check your alkalinity. From your ph I'd say it's likely high.
Also your nutrients are crazy low it seems. Are you running gfo? Or chem media with gfo?

Yes. If you find you need to add back, do so very slowly and test as you go.

Thanks for the help

 

[Willy43]

Should I add any thing or let the phosphates and nitrite come up by them self by feeding like I have been?

This exact thing happened to my son's tank almost 2 years ago.
Diesel helped me through it.

Yes take gfo off line, reduce flow through bio-pellet reactor and feed. You may need to add nitrates (spectricide stump remover) and phosphates (phytofeast ). Those are what I add.

Keep testing. Since you don't really have anything else in you tank you can afford to go slow.

Thanks for the help I removed bio pellets I left a small amount of GFO I have problems with green hear algae I left carbon. I have Chaeto in the sump.

Gha and most algaes will grow with even less nutrints than corals need. While your numbers are low it's a good time to scrub and add CUC so it has a hard time growing back.

I reread my thread you pull gfo off line completely but bio-pellet need to be stepped down. Reduce the flow through your reactor.

Diesel explains it on second page.

I have a CUC

Thank you

I just did a water change. I do around 20gl a week it is a 120 tank

Thank you

I will read the post

Thank you

Check your magnesium levels

 

[Willy43]

heck your magnesium levels

I was about to do that. I dose BRS two part and have almost used a gl of each.

 

[Willy43]

Here are some pictures of what I have pleas over look the wiring I a working on trimming every thing out.

Magnesium is separate from the two. Part with low magnesium your calcium can't be absorbed by corals coralline algae ex.
