Ok, I'll stop posting but just can't resist one question @ Primous
Which bottled bacs have you tried?
snazy yup, pretty much most of us start out by taking advice from our lfs who are there to sell us something which is a huge mark up to them. So in short yes, I used 3-4 of these bottled bacs repeatedly. Unfortunately I didn't document it, I just wasted my money blindy

But I am going to get a lot of nasty responses when I document this here, as I don't change the water during the Tetra Safe start cycle, otherwise it's a waste of money
