High Silicon, problem?

[Zoajohn]

I have been having issues with LPS, mainly euphyllia and Acans dying slow deaths out of the blue. It coincided with a Dino outbreak. The Dino’s are pretty much gone now though. I got my ICP test results back and it showed rather high silicon levels. The reference value at Fiji is zero. Is this a big issue? How would I have this level when using RODI?

There is silicone in seawater. I dont know why they are saying 0. Its one of the most abundant chemicals on the surface.
~1ppm should not cause issues with your corals. In new tanks Silicone can lead to diatoms but many tanks dose silicates for some creatures.

Any more information on your tank?
Alkalinity?
Nitrate?
Age?
Any changes?
Etc.

Glad it’s not a big issue. It just seems higher by a decent margin than most other people’s ICP tests I’ve seen posted.

I checked all on Tuesday:
-8 months old
-8.3dkh
- NO3 5ppm
-magnesium 1300
-most of these issues came about after changing RODI filters to smaller micron sizes. However my TDS is 0 so don’t see how this would’ve caused anything.

Flow or lighting changes?

Added and fish inverts lately?

The only problem that elevated silicate seems able to cause is excessive diatoms. If you do not have a diatom problem, I would not worry about silicate.

Lighting was turned down a good bit while fighting Dino’s. Could sps tolerate low light for an extended period of time better than lps?

Do any of those other results look bad? I’m at my wit’s end figuring out why my LPS are slowly receding

Lps like more nutrients than sps in general.

Also dinos can produce a myriad of other issues: toxins, nutrient uptake is faster than corals so can use before the coral can.

I have detectable nitrate and PO4 so I don’t think nutrients should be the issue. I’m noticing some brown patches coming back on the sand since raising my light intensity, afraid the Dino’s might be coming back
