Hi all.
Making several ICPs of different brands, always high levels in potassium and lithium appear. Potassium always around 600-700 mg / l (correct value: 390-410) and lithium about 500-550 mg / lg (correct over 175).
It is a 1000-liter system, with osmosis water and a lot of water changes almost daily (salt tropic marin pro reef and Aquavitro salinity, alternating), since it belongs to a store, about 12 years working, no major problems are seen, all corals work well, soft, lps, sps, acroporas etc. Filtration is simple, only live rock and skimmer, rollermat, recirculation, no sand, nutrient levels are kept rather low, no3 1-2ppm and po4: 0.01-0.04.
For alkalinity I use Seachem Fusion 1 and Fusion 2, stable levels of it by Kh Keeper and peristaltic. I have been using Red Sea No3-po4-x in a small amount to maintain nitrates for a few months, but the K-Li levels were already high before, so I do not attribute it to that product. I do not use other chemical additives, only very sporadically some test product. I only use food for corals twice a week, classic and not in much quantity (Aquaforest, Fauna marin, Reef roids, easy booster (phyto), but nothing stable, continuous or over-added.
Could these two elements be being added in excess by Seachem's Fusion 1 and 2?
What other sources of those elements could be adding it?
How bad is this excess for corals and / or the system in general?
Thank you.
