Melafix plant safe?

its pretty safe in all regards imo ...

I've never seen it do much of anything but provide peace of mind. It doesnt effect my plants or bio-filter in anyway whenever I dose it.
 
I've never had a problem when using it with plants in my tanks. It has never hurt my tanks in any way that I have seen.
 
btw i heard a great tip that using pond dosages of Melafix can save you money as its the same price but more concentrated. You'd have to do the math to adjust the dosage however.
