Found some on Ebay and so far only place that will ship to canada. Stuff is so damn concentrated so I think a small 8oz bottle will last me until it expires (it does expire right? is there a date on the bottles?) 16oz is only 10 buks more but no sense in getting it if I wont be able to use it.
0.5ml for a 60 gal system should do? Maybe I should rebottle and sell it locally so it not such a waste.
