High tin, Help.

[ReeferSurf]

Tin levels:
13.04.17 - 4.733 µg/l (water change 2 weeks)
15.05.17 - 7.263 µg/l (water change 2 weeks, replaced cheap pump in case tin coming from it with ecotech pump and wave makers)
13.08.17 - 6.063 µg/l (water change 2 weeks, remove pvp/taps in, no dossing of anything in case tin in it)
(All sps from cutoff were going good, all wild were going good too.)

21.11.17 - 13 µg/l (disaster, water change got less, night time torch finding its pest maybe and not tin)
27.03.18 - 13 µg/l (disaster 2 month water change, algae galore)


Hey guys, Getting around to trying to fix my tank up, all sps and some other corals lost, only left with few remaining lps and zoas.

Im about to do a full reboot, redesign rock work, remove all sand in case of a screw or something hiding beneath it. Will start off bare bottom until i find the root of this tin problem.

Im guessing the other metal thing near my tank would be ecotech led stands which clamps on the back wall and is in the water but would have many complaints now if it was a problem.

Any thing else i should check? Or how to go about this. Would Love to get my tank alive again.

Do you use RODI water?

Hey, Yeah I use rodi water from the start, have replaced all cartilages at once a while back as well to be sure.

Metal parts, but tin can also possibly come from PVC and even glass.

FWIW, I'm not sure the problems relate to the tin.
