Hi, I have got a small clam last Tuesday and read it requires Iodine and Strondium, so I bought Salifert test kits. The kits arrived today and test result comes back at 0 for both. And my calcium level has dropped dramatically from 440 to 400 since last Friday (i dose calcium chloride daily and calcium has been consistent at ~440 before the clam arrived). I'm using Red Sea Coral Pro salt and the myBatch result doesnt have a iodine figure and no where on their website has they mentioned iodine concentration........should I treat my salt as iodine free?

At this point, should I start dosing the two? Any clam keepers notice a decline in iodine and strondium?

I have never tested them but I dose 4 drops of iodine once a week everything I think benefits from that. Strondium never tested or worried about. And I have had my big clam I have had probably 3 years or longer. And I picked up a maxi couple months ago. I got pics in my build thread. I manly worry bout alk and cal. But I am no expert.

I do not think there's any evidence that clams need iodine or strontium, but it's a fine experiment to dose them to NSW levels.

It's unlikely you have 0 strontium. Try the kit on some new salt water.

ALL salt mixes contain iodine, but algae can deplete it fairly fast. I'd get a kit before dosing anything but very small doses that may not be useful anyway.

Thanks I'll try them out on fresh fix. I do have some nuisance algae and macroalgae that might be why iodine got wiped out, but im also very surprised strontium tested 0. the test is quite complicated, so I might have just messed it up lolll

I thought dosing iodine was a waste, that it had to be iodide?

I presume he means dosing iodide.

Iodine is an ambiguous term. It correctly describes the atom I in all forms: molecular iodine (I2), iodide (I-), iodate (IO3-), Lugols (mix of I2 and I-) etc.

It isn't worthless to dose I2, but it is much more complicated than many folks recognize since it is dosing a reactive and largely unnatural form. It will become iodide and iodate eventually, but along the way has other effects, including potentially impacting trace element bioavailability by oxidizing some of them.
