HI FM team,
I could use some help with some very strange readings...
I restarted my tank due to a majano boom. Bleached the rock for 4 days, washed it several time with freshwater and restarted the tank. I did my first ICP at sept 28 with unmeasurable high manganese and high iron & chrome. I used a not so well known salt so I tought the salt mix was bad... Emptied the tank, filled it with fresh water, washed everything for 2 days then emptied again, refilled with RO water and now I used fauna marin professional sea salt. The oct. 25th ICP is 3 days after filling it up - still shows very high manganese and iron.
I checked every single pump - no rust, no damaged magnet, nothing... Tank is empty, only a skimmer jebao return pump and jebao flow pumps. All magnest clean and free of dmg. For rockwork I used Aquaforest stonefix cement, around a half a bottle.
Any idea what may have caused the high metal? Could it be the bleach (used the most simple one with no additives and washed the stones well - also did several 100% water change since that...)
Is there any recommended method to remove the manganese from the tank?
