any updates here on copper?
On my last triton test my copper was 7 ppb and I am not sure where it is coming from. I do not run any GFO, no metal corruding in any pumps, etc. I do have a lot of copper piping in my house as my house was built in the 50s but I run a RO/DI. Could some copper still get through the RO/DI?
Other high heavy metals:
Tin (Sn at 4.3)
Copper (Cu at 6.97)
Aluminum (Al 8.5)
Silicon (Si 273)
Lithium (Li 453)
I am just trying to figure out what is affecting my corals. It is causing very very slow stn till they completely die usually. Snails and fish look fine. SPS look great in my tank till about 2-3 weeks then they slowly get stn and look bad. My alk is very very stable at 7.7, I check everyday. Calc is 420, p04 is .02-0.05 and nitrate is between 4-8, salinity is 1.025-1.026. I dose flatworm stop, coral booster and 2 part. TDS was showing 002 but I changed all the filters on my 90 gpd spectrapure and I am also adding another carbon block and another DI canister. Will that help with making sure I am getting all copper out of the tap? My salt is instant ocean.
I was thinking of adding a polyfilter but it sure seems like that will do nothing, if anything could raise my copper level?
