Hi All,
I would like to hear your thoughts on the results of a recent ICP test. I have a SPS dominant redsea reefer 250 (~65 gal total volume). The tank is looking reall good (see video link at the bottom), but the result revealed a two elements are off the charts...
Sulphur is a 2287 mg/l (vs. 900 mg/l setpoint)
Iodine is 147 ug/l (vs 60 ug/l setpoint)
Po4 is higher than expected too, but that is on purpose, so not a concern here!
Ok, i am currently using the regular instant ocean for salt; and i try to maintain salinity at 35 ppt. I was trying out the new seachem vibrant sea salt; i used up a full big container (220 gal?) before switching back to Instant Ocean in December. I do 15 L water changes every week. I run seachem matrix carbon (a small amount in a phosban reactor). I have 50X waterflow in the tank and i use radion xr15 lights.
I dose:
kalkwasser in the ATO, which is sufficient for maintaining calcium in my system
a little redsea foundation buffer B for alkalinity (around 9.9 dkh)
Redsea foundation buffer c for Magnesium.
Seachem flourish phosphorus
Several months ago, i played around with dosing redsea coral colors and potassium nitrate to improve SPS colors, but i discontinued that after getting a major Dino bloom. I managed to get over my dino issues by dosing seachem flourish phosphorous to maintain po4 levels above 0.1 ppm, along with 5 to 10 ppm nitrates.
I feed 2 or 3 times a day, either frozen mysis, NLS pellets, or a homemade mix of shrimps/fish/squid/oysters ground up in the food processor, then frozen. I also a bit of nori twice a week; the nori i use is from my sushi kit... not from the LFS.
ok, so for iodine, perhaps the high levels are from dosing a bit too much a few month ago, or feeding fresh seafood?
The elevated sulphur is perplexing however. Could it be some preservative in the nori i use from my sushi kit ? Should i be concerned about the high levels ? My tank is looking really good right now so i am hesitant to change, but if high sulphur can have some negative long term consequences, then perhaps i need to do something to keep it down.
