A little background. Been doing this 35 years. My tank is 60% sps, mostly acros and all are thriving. Color isn't the best but I'd put my tank up against any other in terms of growth and polyp extension. Tank is 220g . Led/T5 combo. Algae scrubber, skimmer. Dose 2 part. Tropic Marin Pro Salt.
This tank has been up a year but was transferred from a smaller tank which was up for about 3 years.

I have been using KZ Coral 1-4 weekly with my 10% water changes.
I also dose KZ Amino Acid Concentrate LPS, Acroglow, Pohl's Coral Vitalizer. Supposed to use these every day but I probably do it 2-3 times a week.

Almost never feed but when I do I use RS Coral AB+ or reefroids.

Sent in ICP because I had a few laying around.

Results came back with 3 elements high

FE 7.00 µg/l
Mn 11.00 µg/l
Li 388.00 µg/l (setpoint 200)

The curious one to me is the Manganese. This is in KZ Coral #1. I dose the exact amount they recommend.

Are any of these anything to worry about???

Should I stop coral#1 with the manganese in it??

Have no idea where the Iron is coming from. Have 5 stage RODI and always comes out 0. Checked a million times. Almost all equipment is less then a year old, no rust and no metal has been dropped into tank. Copper pipes in house.

Should I run a poly pad???

It also said to dose Mg, I, and K. Should I do this?? I did dose iodine because I had some.

Thanks for any suggestions.

Randy, looking for you.

I would not change anything because of those readings. I don’t think any of them are an issue.

While it is overkill, IMO, Red Sea recommends iron to be 14 times your level.
