Coral growth lab results

[Aries360]

Hello and good day everyone,
I sent my water out to be tested and these are my results. Anyone have any idea why my coral doesn’t grow? There are some things I can’t control because it’s a lot of fish in my 360g so I know my nitrates and phosphate will be a little elevated. I’m running a phosphate remover media to the max. Like by the gallon. Not sure if even dosing will help? Open for suggestions, lights are x30 blues. I can grow some coral better than others, like cabbage leathers and mushrooms. But then I add other leathers and they shrivel up over time and never really open.

 

[Mr. Mojo Rising]

the nitrate and phosphate is very high.
But if your corals are not growing, the first thing I'm looking at are the lights. Do you know the par value's in your tank? Lights are 90% of it, and threads about corals not growing often come down to low lights. Some LFS's rent out par meters, it might be worth it to rent one to know exactly.

 

[Aries360]

The lights are brand new radion xr30. But yes I did borrow my local stores par meter and the readings were perfect but I don’t remember the exact reading. The phosphates I just can’t get down regardless of water changes. Nitrates fluctuate depending on water changes . I feel like something is missing

 

[BryanM]

That phosphate number is sky high. I would start to slowly reduce that.

Nitrates also high, but to me not as worrisome.

Open to suggestions. Tried kolar gfo and rowaphos. Hasn’t made a dent and used over 5gallons total

Are you using RODI water and doing regular water changes?

 

[Aries360]

Yes rodi with meter before and after putting in no nutrients in water and yes regular large NSW water changes

Just throwing out the obvious but the nems aren't stinging the corals and causing them to not grow?

Phosphates inhibit growth for some corals, right?

How are you using the rowaphos? In a bag or a reactor? I saw way better results in a reactor. Took along time though to get po4 to come down as I’m sure the sand and rocks were full and needed time to slowly remove.

The nems aren’t touching any coral for the most part

Both in a reactor and bags . I have bare bottom but lots of rock

Honestly its a bit of an unknown or disputed topic. But generally high nutrients people believe encourage excess algae growth, which can bother/hinder corals.

Following as I am also on a no growth, my ICP is close except barium which is high.

 

[DatReefGuy]

I think you might be lacking trace elements. Your iron is low and iodine is also low. Also, how many circ pumps do you have in there? Temp?

 

[Aries360]

Bags and reactors. Changing reactor and bags frequently

Temp around 78. And three circulation pumps. Does low iodine and iron make that much difference?

I use natural sea water, do you? Or do you use salt mix?
