in a nano especially a 6 g you should be dosing anything at all
I think you meant "shouldn't" right? lol
WHat people dont seem to understand about PurpleUp is that it is just another form of Ca. If your Ca levels are where they should be, there is no reason to dose this stuff. BTW, there is Iodine in there too which is not a good thing to overdose... there is some evidence that it can be harmful if overdosed actually. Also, there is strontium, magnesium and carbonate. So you arent just dosing ca when you are using this product.
Patience, proper Ca, Alk, and Mg levels, and actinic lighting... that should give you good purple coralline growth.
