No need to dose iodine or strontium, unless you suspect there's a problem. If everything is doing okay, then you don't need to use any extra additives.
Dr. your fox is looking damn good, i saw it on that other thread!!
Hope mine will look like that one day.
So one only add iodine and strot if their is something wrong???Like what?
I added some every week,is that wrong?
If you don't need it, don't add it. Unless you determine that there's a need for iodine or strontium, don't use them. It is possible to overdose a tank just as easily as a tank can be deficient in something. And if you are not testing for it, then you could be adding something you don't need.
