Hi aquaforest

First I would like to say I love your products, my tank has been running for 10 months with no water changes ( I know u recommend water change)
I dose components 123 and abve and used reef salt, I use marin lab icp tests every 4 months my results are good the only element that has been going up is lithium. It is now 1.6 mgl what af salt is best use to bring this down?
Does any comments bring lithium up?
Is this a dangerous level?
Any help is much appreciated.
Po4 0.05
Nitrate 0.5
Calcium 470
Mag 1400
DKH 7.2
500l tank
Dosing 35ml day 123
All sps/corals look great.

Your Lithum level is 0,160 mg/l (ppm), right?
This level looks perfect.

Aquaforest Sea Salt has low levels of Lithum but We don't recommend to use this salt when you have corals in aquarium.
